Great video, mate. i have a hpd catch can in my crd zd30 patrol ... watching this very well explained video has me looking at swapping out my hpd unit for a provent unit. thanks mate
Nathan, I did a oil change last weekend on my 2018 Holden Colorado, 5,100km since previous, and had about 80mL drain out of my Provent 200 can. So that's oil and other muck that didn't have to find it's way back through the intercooler, turbo, inlet manifold, and through the cylinder, and what doesn't get burnt up, into the DPF. Prior to fitting the catch can at about the frist 9,000km the DPF had come on three times. It's now got over 25,000km on the clock and the DPF has never come on again.
Good results. It's interesting to hear the changes in the DPF burns (something I can't comment on with my model). At least it provides that confidence and peace of mind that you are getting the cleanest air back into the intake. Cheers.
@@chasp_0784 That was 25,000km less 9,000km, so 16,000km without a DPF burn. It gets even better(!). Since I posted that I'm on 36,000km, so now 24,000km and it still hasn't done one, or it hasn't told me it's done one. It use to come on and I'd have to drive about 30km at highway speeds for it to complete. Anyway, if it's not possible it's not possible. I change the oil and drain the catch can regularly, keep driving it, and never get any DPF messages, but maybe it's doing something in the background and not telling me.
@@Michael_Mears yeah fair bump mate, I think it’s doing it in the background but no dpf issues is a good thing, people think Toyota owners got screwed, I worked for Mercedes in England and every single day there was multiple diesel emission jobs going on, sensors, regens, replacing whole catalysts, injectors. Rubbish product.
@@chasp_0784 Hey, reading that, you've given me something to think about. I should get the local mechanic with this scan tools and see what the stats are with the DPF, or history, or whatever can be gleaned from the ECU records. It might give me an insight into what it's doing. Point taken about the work that goes on. If this Provent unit can help prevent or significantly delay some of that type of work, that would be fine by me. Cheers.
How RU-vid knows that I am on the hunt for a good catch can system is a mystery but this video was extremely useful on swaying my choice towards the Provent 200.
I have been running a provent 200 for a year on an ecodiesel. It helps a ton. I drain it every month. Your test is really accurate on how effective a catch can is.
Nathan, Great video. With the new Provent 200 filter element, the vent valve is in the bottom of it as shown clearly in your video. This means that if the pressure is high and it opens the inlet fumes are vented directly to the outlet. Normally this is fine but if the outlet hose to the air intake is kinked or has collapsed, serious damage to the engine could occur. No doubt Mann and Hummel have done this change to meet emission requirements. I think there is merit in leaving the original vent valve in the top of the canister intact.
Excellent comprehensive test mate. Had the Provent on my previous Navara which worked really well, and have ordered the same passenger side kit you are running, and also a pre fuel filter kit for a 200 series VX due next month. Will be nice to have installed from the get go.
I don’t own a forby but I do own a vw polo diesel as my daily. I learnt about Mann and Hummel provent sometime ago. I did some measurements and quickly discovered that the provent 200 simply was too large to fit under the bonnet of my little front wheel drive. BUT I discovered that the provent 100 would fit perfect in a particular spot! So bought it,installed it. And just for the hell of it I used 19mm clear petrol proof hose from Bunnings. This provent does work. In 20,000 kilometres I have drained it three times and got about 200 mls from each drain. A filter change at 20,000 and we’re good to go again. And as for the clear hose, well the intake hose going from the rocker cover to the catch can is definitely black and oily internally but the hose going from the catch can back to the air intake which is just before the turbo,is still quite clear! Which just goes to show that yes,these genuine ones do work.
Hey mate, thanks for sharing. I'm glad you were able to get the smaller 100 unit to fit! I love the idea of fitting a clear hose to the can, another awesome way to visually observe how effective these catch cans are. I'm glad you are happy with the results from yours, as I am with mine. Cheers, Nathan.
Thanks mate. You’ve convinced me to change from HPD to Provent. I currently have a HPD setup in my Colorado. I’m getting a new V6 Ranger in October & will install one asap 👍👍
Found your channel randomly after searching catch cans, nice clear and concise info! Great video! I'm researching catchcans for my 2006 Mazdaspeed 6 (MPS6) which has a direct injection system similar to diesel motors. Thank again!
This is the best Provent 200 test video on youtube so far. Thank you for your efforts! How much oil have you collected during the next 5000 km intervals?
Hey great video. One correction - EGR has nothing to do with saving fuel it is solely there to reduce NOx emissions. It lowers combustion temp which lowers NOx. No affect on fuel use.
Nice video. I'm in the USA and have a catch can on my Trans Am but need one on my new V8 Saturn Sky (converted from the turbo 4). There are so many brands of cheap home-made stuff for performance cars but nearly all are essentially the same - some metal pot scrubbers and a mesh filter. Only a handful even seem to consider air swirl, actual oil precipitation, or have large enough volume. I've seen 500HP Corvettes have catch cans with 8mm hoses to and from the can, not nearly large enough to handle a lot of air. I found the ProVent and am researching it - seems great. Thanks for mentioning the Curtain University paper, I'm glad to see someone did some real research. And this video you do your own comparison with the cloth, that's great. I'm going to get a PV200 or maybe even a 300 series. Thanks again.
Hi Nathan another great informative vid you are spot on with amount of oil the can catches. A few knockers don't like them possible they have in shares in Toyota , mine is a Flashlube proportionally at 5-6k I caught a similar amount of oil .I drain it around 5k to be sure .cheers Ian.
Cheers mate. Each to their own, I'm not here to sell, promote or push products, simply to display my results, thoughts and opinions on these popular modifications. I believe they assist in prolonging carbon build up and don't have many, if any drawbacks. Cheers, Nathan.
Cool video. You just forgot to mention that if you do an EGR block you’re actually going to speed up the blockage in your DPF. EGR is there for a reason dude! Apart from failing to research EGR and DPF systems properly you did a good job.
Perhaps I forgot to mention this because I don't have a DPF. DPF vehicle's are certainly different and specific considerations need to be taken into account, but I highly doubt I will cause damage to a DPF if I don't have one...
Cheers mate. Good video. I'm buying a new Fortuner and having Toyota fit a ProVent 200 to the car. I had to fight with the dealer principal because he claims that Toyota will not honour any warranty issues in the future because I've had the catch can fitted. I've insisted on the install. I honestly believe that the dealership want engines to have issues so they can make money from the repairs.
Thanks mate. Yes, I hear you. The dealers don’t like to know anything about non-standard equipment. I’m glad they eventually agreed to sort it for you. Enjoy the new vehicle, great choice 👍
Another cracking video mate, well done and thank you. Mine goes in next week, 2020 Lc2000 with nearly 10k now on the clock (already! Only picked it up in November).
Nice video mate. It’s also worth noting that if there is a significant buildup of sludge where the EGR combines with with the CCV system, it’s worth checking that there’s no cracks or anything in the intake system that might cause the sensors to be reading an incorrect amount of air flowing into the engine and thus over-fuelling, causing more particles in the exhaust than is necessary.
Really good informative video. I’m thinking of fitting an oil catch can to my D40 Navara, after doing an inter cooler clean. Thanks for the clear and concise tests and results 👍🏻
Thanks mate, yes this is true, however keep in mind the EGR is a dynamic system, so when under heavy load or full acceleration the EGR is electronically disable by factory computers. The EGR will only provide emission benefit when at idle or slow speed.
Good job mate Don’t forget about the condensation diesels get with the larger oil capacity , mix those two together and unburnt diesel and that solution becomes acidic and start eating at your seals. ☹️
Yeah, I have heard about the condensation issues. The reason I didn't mention in this video is I haven't had any issues with this so far, makes it hard for me to comment. I believe keeping the entire system, the unit and hoses in the warm engine bay would definitely assist in reducing condensation. Cheers.
I bet adding a slow-drip release system to trickle seafoam into the catch-can’s return-to-intercooler hose would steadily keep the entire intake clean and perhaps eliminate the major servicing event
Hi Nathan, As a matter of interest after 11500kms in my 2021 dmax , oil drained including filter amount , 320ml. at least the excess is not finally ending up in the DPF and so far have not had the DPF burn
Best real world before and after test of a catch can I have seen on YT. The Provent 200 is the first mod I fitted to my 200, second was a a secondary fuel filter. Both installed pre delivery from the dealership. Well done Nathan 👍
while i think these are a good idea if it's made from the car markers for that specific engine, as they still allow the engine to breathe the right amount. The issue i have with them also is if they fail, values can get stuck or fail which will cause a lot of pressure to build up and that will cause leaking / blown seals. I know Toyota/Ford can be funny with these things if you have a factory warranty as it can give them an out to fix warranty issues. Another thing is if the motor is old and you're having a decent amount of blow by start at look what might be the cause, (injector rings, can be one major cause) or if you have a rebuilt/modified engine that can cause a lot of blow by as well. Catch cans are a band aid fix in most cases, and most people that are promoting these are the ones who have some vested interest in them.
Hey mate, can definitely see where you are coming from here. Although I can agree to some extent, a unit like this does include fail safe and pressure relief valves that should (theoretically) prevent damage in the event of a pressure build up. Although manufacturers did design there vehicle in a particular way, engines need to breathe, however combustion engine were never designed to recycle that contaminated air back into the cylinder. This was only done for emission standards and a unit like this will help to purify that air prior to re-combustion. Hope this makes sense and by no means discounting the points you have raised. Cheers, Nathan.
one thing has been overlooked here.....WHY is the engine creating that much oil vapour in the first place??.....i myself own a late model common rail turbo diesel 4x4....after reading the owners manual, i discovered the suggested oil grade to use is simply too thin for Australian conditions....Australia has a higher ambient temp that europe/eastern countries year round..higher ambient temps means going to a thicker/heavier grade of oil.......the oil grade suggested in my owners manual was 10w-30 oil......i have changed to 10w-40 oil and have seen a marked difference in oil vapour coming out of my rocker cover breather hose......just my 10 cents worth of hands on research and experience....cheers..
Great vid again Nathan! What I would like to do to my (future) Prado is install both the catch can and a EGR plate with a 7mm hole in it to prevent the engine light coming on.. best of both worlds 😁.. cheers Nathan🤙
I agree with catch cans! I’ve collected heaps of crap! I’m on my 3rd filter and everything is clean! Intercooler and intake manifold! Best money spent!
egr gas will still cause a dirty intake even if you are running an oil catch can. the difference is that the soot is drier and less sludgy. but it still evident.
Yes, this is true. The gases will mix and cause that sludge. The EGR will still produce residue, but it will be drier and less likely to build up in the intake 👍
I actually just watched the video by Auto Expert who thinks they are useless. I went to put a comment about how my intercooler was full of oil before installing one, but comments were turn off 🤔
Each to their own, but I’ll continue to leave this installed on my vehicle. Oil alone won’t do any damage, but it’s the combination of oil and EGR gasses that will slowly block the intake... leaves us wondering sometimes...
@@XploringOz In the video he states that catch cans are just catching the oil vapour before the engine can deal with it through its own ventilation. So my intercooler filled with oil begs to differ.
Always take John Cadogan with a pinch of salt. I notice the very next video of his queued after I watched the catch can rant was about not buying a 2020/21 Honda... which kinda blows a hole in his own "reputable manufacturers know best" approach to avoiding catch cans.
Another thoroughly thought out experiment clearly indicating how important catch cans are and the effectiveness of the provent 200. Thanks heaps Subbed👌
I agree that they are worth fitting to various diesel motors .... fitted one to my V6 Diesel Touareg... 20000k later I’m yet to have to empty mine so i suppose it depends on the amount of blow-by your motor has / does on how necessary it really is and of course how long you intend on keeping the car.
@@nategilmore8941 ... Mines actually the Ryco branded model... Ryco RCC350K... I had a bracket made up to fit it... I have mine living in the front left corner.... easy enough to do once a bracket is made... you cannot buy a bracket for these cars as far as I know.
Catch cans are great if you don't mind spending thousands on having the valves adjusted far more frequently. On this engine type you'll be purchasing different sized buckets to offset the additional valve recession caused from all that oil not being there to lubricate. Ask yourself this basic question. 'Why doesn't Toyota and every other manufacture not install these aftermarket oil catch cans from new? It's because they spend a metric tonne of cash testing and developing an inbuilt baffle to control the amount of oil vapour flowing through the intake. So in short, there's already a system in place controlling these requirements to prolong the life of the upper cylinder and valves. Also, EGR doesn't inject dirt into your engine, it's soot and exhaust gas, nothing else. EGR reduces noxious exhaust emissions, increases fuel economy and lowers the combustion temperature. It does so by recirculation of inert gases from an already depleted oxygen supply, not as much oxygen to compress which reduces pumping loses and less heat is lost through the engines cooling system, less heat energy wasted equals better economy. Having oil coating your intercooler isn't going to change much at all considering it's great at transferring and absorbing heat energy. That's why oil coolers/heat exchangers work so effectively and they are full of it. I find 95% of the 4x4 community has no clue about what really happens, it's all regurgitated horse crap from people who are feeding on the hype such as ram air from a snorkel, catch cans, egr and dpf delete, chip/piggyback ecu tunning whilst all being told none of the above affects the warranty.
I completely understand where you are coming from, however have a different opinion on the matter. I understand the role of the EGR system and am aware that it doesn't inject dirt into the intake system. I further understand that oil residue from the crankcase recirculation system (CRS) doesn't hinder engine performance. However the mixture of these two system in the intakes creates a sludge and restriction on the intake pipes and most definitely do effect engine performance/efficiency over time. Further, yes EGR system do slightly benefit fuel consumption and will help the engine run cooler, however this is nothing the standard variable cooling system can't handle. After all, all engines ran fine before EGR's. EGR's and CRS's are only added to reduce emissions, not to benefit the engines performance or longevity.
Do yourself a favour and go pull off the intake manifold of a recent diesel with a catch can and one without. You tell me which one is the healthier engine you. It seems you are the one that doesn't know what you are talking about.
Hi Nath. You nailed it yet again. Very informative and easy to understand. A question I have for you. My 200 just ticked over 17k and I found some oil that I need to drain from the catch can. How often to I need to change the filter inside ? Toyota wont do it as it is a third party add on. Thanks again
Thanks Jim, so it will depend somewhat on how much the unit is collecting. I believe Mann and Hummel recommend changing the filter every 30-40k kms. I will probably lean towards the 30k mark due to the amount my unit is collecting 👍
Blow-by is not the only gases. Many diesel engines have a vacuum pump for engine controls and brake/clutch assist. These Vac pumps usually dump waste air into the engine block to move through the PCV system. Element on the ProVents are not paper, is polyester weave. Your theory on EGR lowering EGT's is not correct. EGT's raise with any ingestion of spent gases that are already hotter than amibient but less available Oxygen results in higher combusition temps.
I have had a provent 200 installed since truck ticked over 140k, now at 300k and last clean of pipes and intercooler it’s significant cleaner and engine breathing better. Don’t skimp and get provent and don’t look back. “fourbyfour” channel is wrong with his dislike of catch cans.
For sure, I agree with this. Keeping an eye on these units and replacing the filter elements at regular intervals is also important for safety and efficiency. Everyone will have their own opinion, however this video reflects my view on the matter. Cheers, Nathan.
Good work! Regarding the increased crankcase pressure myth - not sure it has been dispelled yet. Do you think it would it be possible to measure crankcase pressure firstly with the catch can and long hoses and secondly with no catch can and just the short factory hose? Second unanswered question for me, is whether the small amount of oil that still gets through is enough to still make black sludge, given that 99% of people who fit catch cans still have a working EGR. If so, will we find the intake is still dirty after say 250,000km despite all the oil removed by the catch can? Might take many years to know the answer to the latter.
Thanks mate, so yes it would be possible to measure those pressure. However saying this I don’t currently have access to this equipment. Personally I wouldn’t be too concerned as the pressure is low to begin with. Secondly, yes this is very true, however the build up would take much longer, given a more efficient intake for a longer period of time.
One more question regarding the Ford focus RS. If I do install the oil catch can and the oil baffle replacement which is not designed correctly, What is the estimated miles before you have to clean the intercooler and the intakes? Also what’s the best way to clean the intakes once they carbon?
Fantastic video. I have Landcruiser 200 GXL and fitted Mann & Hummell Provent 200 from brand new also purchased from Western Filters. Does a great job. Should I upgrade to the Internal Ventilation kit? From what I can tell only diff is internal ventilation on new one versus lid pressure relief valve venting to atmosphere.
Thanks mate, glad you enjoyed the video. To be honest, there's nothing inherently wrong with the original kit (other than the environmental concerns). From what I am aware of, you can just upgrade the kit when you next replace the filter material. These kits come with everything you need. Personally I wouldn't be changing the element out just for the upgrade until the regular service interval (normally around 30000kms)
You think a Provent 200 or 400 is best for a Twin Turbo 5.0 Diesel V10? Thinking a 200 each side, to not lengthen any hoses - or a 400 in the V when I remove the EGR Cooler/Parts to see the Alternator deep under XD (essentially 2x R5cyl 2.5 TDI's from in a 2005 VW Touareg)
Thanks mate, glad you enjoyed it. Installing a catch can will definitely still have an effect on catching some of that oil, however it won't be as important. Without an EGR system, you won't develop the 'sludge' that builds up in the intake and therefore won't have a long term restriction. Saying this, the oil that can flow through the intake pipes without a catch can fitted can also effect the thermodynamics of the intercooler, creating a slight increase in intake temperatures. In conclusion, although it's not quite as important, there are still benefits there to fitting a catch can. Cheers, Nathan.
Nathan I fitted a Provent to my new NX 3.2 Pajero as I had one on my previous MN Triton which did 280k and the intake manifold and intercooler was very clean upon inspection. So one thing I way throwing about is what about doing both a catch can and EGR delete or blank off, any thoughts as i had read so many mixed reviews about doing or not doing the EGR delete, would love your comment, just for info 9200kms has yielded 120ml in my Pajero obviously your 200 being a V8 has yielded near double that. Love your thorough segments, well done mate.
Hey mate, glad to hear you enjoy the channel and have found this video useful. So there are a couple of things to consider. The EGR system is completely seperate and (generally) produces a dry gas which can contain small debris particles. This is no issue by itself and will just pass through the engine as designed. The EGR intake is generally after the intercooler and immediately before injection. However, when the EGR gasses (and small debris) come into contact with that sticky blow by oil this is when it becomes a little bit of an issue. The crankcase ventilation system (CVS) is generally positioned prior to the intercooler and hence why the intercooler can also gum up with oil residue. Anyway, when that oil residue from the CVS meets with the EGR gasses in the last part of the air intake system it creates a thick and sticky sludge over time that can eventually reduce the intake diameter and overall efficiency of the engine. Theoretically, placing in a catch can, this will prevent this build up, however we also know that even the Provent 200 system is not perfect, which means a small amount of oil residue will inevitably get through. This in turn will still mix with the EGR gasses and overtime time (a lot longer time) create that sludge build up. It was take significantly longer though. So yes, blocking the EGR will definitely provide some benefit in that regard, however also keep in mind the legality of this if that is something you consider... Now some people will also say that the engine will suffer somewhat from blocking the EGR, in particular with overheating. The engine is tuned to run with a functioning EGR valve and when in use will result in a cooler running engine, as the intake air is partially burnt gasses and won't be able to re-ignite. Saying this, almost all modern day vehicles will be able to handle this very small increase of heat with a standard alternating thermostat. I hope this can of help. Cheers, Nathan.
Hey mate I have a 2011 model cruiser and instead of the catch can what is actually stopping you from getting a hose from the crank case and just putting it to the ground like older engines and letting is vapour like that and than plugging the hole on the air intake ? Thanks
Hi Nathan. I'm a fresh subscriber to your videos. Loving your methodical and very informative approach on what your doing...just brilliant. I had a big binge tonight. I Come across your catch can vid here and I've paid close attention... I think. You say if the provent filter blocks or has a problem it will vent the crank case gases out through the relief valve that you show in the bottom of the filter, Which is inside tge can, and into the outside atmosphere under the bonnet. How can it possibly do this. Could you check this and maybe do a video. I believe you are wrong. The relief valve in the bottom of the filter just by passes the filter and there for it will just vent it straight into the catch can itself, then to the out let back to the inlet pipe feeding the turbo. Correct me if I'm wrong, but have a closer look at it please. Maybe even simulate a blockage. You'll see what I mean. While your at it check the other relief valve on the bottom side. It gives the catch can and motor as such the ability to suck in unfiltered air. I won't be installing a provent catch can antime soon.
Hey mate, yes I see what you are pointing out here. Without conducting my own test, I would have to agree with you here. The ventilation system would recirculate the gases back into the cooler, just as if the catch can was not there to begin with.
Thanks mate, glad you enjoyed it. So not yet, I haven't done any further testing and to be honest, it probably isn't on my immediate list to complete at the moment. I'm still very happy with the performance of the Provent and will be sticking with it for now. Cheers, Nathan.
Hey mate, it definitely wouldn't hurt. Putting a catch can on will definitely help prevent that build up and the intake clean will just open up the intake pipes. It will just allow the engine to operate as cleanly and efficiently as possible. I had my vehicle cleaned out at about 90k. Cheers, Nathan.
Hi Nathan thanks for the very informative video. Just wondering what Catch can you are using as I went online and there are so many Provent 200 catch can out there. I am assuming they aren't
Thanks mate, glad you enjoyed the video. So this is the updated kit that I've got on my vehicle from Western Filters: www.westernfilters.net.au/toyota-landcruiser-200-series-2008-on-4-5l-td-200vdj-passenger-side-installation-mann-provent-oil-catch-can-kit-os-prov-21p/
Great video. Just bought R51 2010 2.5 TD. 187000KM on the clock. After removing the EGR pipe I can see some build up of oily soot. I presume it would still be beneficial to fit a Provent 200??
Hey mate, so I would still recommend a catch can. It will prolong the continual build up of carbon in the meantime. It could be worth doing a full intake clean as well, just to clear out that existing build up. Cheers, Nathan.
I have 14k on my New LC200 2019 is it too late to install a Proven 200 ? + i live in a Very Hot Country will that be an issue ? Thank you for this great video.
Cheers, thanks mate. So that cap actually came with the Western Filters kit. If you ordered through them, I’m sure they would supply one to you, otherwise I would assume they would sell them as a stand some product. Cheers.
@@jimprovan8866 I reckon hit them up. Another viewer told me that they contacted Western Filters and they sent one out to them. Hopefully they’ll do the same for you 👍
16:03 not 100% effective.., but by the looks of things at least 90%+, so that would suggest a conclusion that instead of ±60000km required clean of the engine intake it would be more like ±500000km engine intake clean required - that would suggest same extension on intercooler cleaning requirement, I think case made.., wonder how effective pro-vent would be on the GDI engines?..
Great informative video thanks for sharing. how many provents does the LC200 need? do both turbos have the vent connected to them? just asking cause my VW has 2 turbos and 2 separate PCV systems one to each turbo. then again its done 265000km so the horse has probably bolted.
Thanks mate, so the 200 series only has one ventilation hose from the crankcase. Making it easy to plumb into a single catch can. The filtered air is then re-circulated into the passenger side air intake, however once that hits the intercooler, the pressures from both turbo's are combined and the gasses mix prior to entering the intake system. I didn't realise the VW had 2 seperate pipes. I'm guessing that a model specific kit would likely combine the two hoses prior to entering into a single catch can... Cheers, Nathan.
Hi mate, I don't if I am missing something but I think it might be good to replace the filter once is completly sought. What I notice is that after is sought air does not flow easily. So one is increasing alot internal pressure on the engine once the filter is drench in oil. I am not sure that one is supposed to extract a bottle of oil from this filter. I also seen this recommendation from other sources. Let me know your thoughts. Thanks for the video also.
Hey mate, so the manufactures themselves recommend changing the filter element every 30-40k km's, depending on how the vehicle is used. The filter material is designed to continue to allow filtering and airflow even when fully soaked. I can't talk too much about the science about it, however it seems to be working thus far. Cheers, Nathan.
@@XploringOz the filter code that you used is the lc5001x I believe correct? I might have gotten a knock off or it can be my oil type causing this or sludge in the motor it self. Just guessing here. What I notice on mine is that is completly black,the oil didn't flow to the bottom of the filter like yours.
@@RafaelCampos91 Hmm, yeah that doesn't sound right at all. I can't offer to much advice here as it's not something I've had experience with. Might pay to take it to a mechanic or a fitter who deals with catch cans to seek their advice?
Thank you for your educational videos!! Just want to ask if the LC200 crankcase ventilation system you mentioned means it also uses a PCV valve (routed to exit through the upper breather box)? or is the system just a plain breather system? Emissions standards aren’t so strict in my country, so i’m thinking to just vent the catchcan from breather to atmosphere and to just block the intake hole. But doing so, if there’s a PCV, i’d be losing vacuum pressure at low RPMs, right? Also, venting out would require an ecu tweak? Thanks in advance!
Cheers mate, glad you enjoy the videos. So as far as I'm aware, the standard Toyota ventilation hose does not have a PCV. If you wanted to vent straight to the atmosphere I don't seeing this being a engine management issue. Because of the low pressure, there wouldn't be any vacuum issues as long at the blanking cap was secured well. My concern would be environmental and road surface. As you would have seen there is a significant amount of oil being captured by this unit, if this was to be released it would 'film' the road with oil, making it a slippery surface for other vehicles, particularly motorbikes. Cheers, Nathan.
@@XploringOz Thanks for your quick reply!! My LC is still quite new so I’m looking at it sometime in the future yet. In case I finally decide I’d probably choose one with an outside filter, and to just collect the oil from time to time, be environmentally friendly. Again thanks!
Could the need for the intercooler being cleaned be the reason that Toyota don't want us to fit a catch can ? Is the catch can taking money away from Toyota service ?
I think it’s just one of those things that bring the expat up too much for consumers by adding these sorts of modifications. I personally don’t believe there is anything sinister here, but you never know 🤷♂️
HI Nathan i can't decide between provent and ryco. Ryco looks well constructed but i believe they had few pressuring issues when first realised old part number Rcc350 now supersede to Rcc351 and I noticed it filters opposite flow direction to provent.Im not keen blew oil seals on our new car.Any thoughts on Ryco unit? Cheers
Hey mate, personally I haven't had any experience with the Ryco units so it would an uneducated opinion, however I can confirm that I still haven't had any issues with my Provent system. Although I will be changing the filter media in the next few thousands kilometres as per the recommendations from Mann&Hummel. Cheers.
Great Video, I just have one question, when you disconnected the hoses for the test, is the flow through the catch can still the same? I thought there was a vacuum applied at the outlet tube so when you disconnected the second line there would be no vacuum to pull the oil vapour through? It looked like you just opened the system.
Hey mate, so I don't believe there is a vacuum on the outlet side of the can, if there is it would be very small. The pressure and direction of the flow is based from the pressure placed from the crankcase toward the catch can. Hope this helps thanks, Nathan.
Hey mate, if you're talking about cleaning the intake components of the engine, I won't be able to comment there. Definitely a job I leave to the experts who also have access to commercial style parts washers. The intake decarb's are a messy and time consuming job on these 200's.
I have a 2010 LC 200 with 226000 klm on the clock . It still runs beautiful and tows my caravan with ease ( loaded weight 2600 kg ) My question is do you think fitting a catchcan will improve the running of my vehicle .
Hey mate, so it probably won't have any effect on the performance of the vehicle. Catch can are primarily designed to prevent the slow blockage within the intake system. The small residue of oil that passes through into your cylinders won't cause any dramas. If you have already, your vehicle could potentially benefit from an intake clean. This will remove any carbon build up and potentially restore any lost efficiency and power from the years. Cheers, Nathan.
@@malmarsden9730 No dramas. If you do a intake clean, let me know how you go and your thoughts on it. I would be interested to hear if its makes a significant difference on a vehicle with this many km's. Cheers, Nathan.
Sure is! Significantly more than the HPD unit caught. At least I'm confident the unit is performing well. Are you also running the Provent 200 on your Prado 150? PS. Great channel by the way mate, been following you for a couple of years now.
@@XploringOz It is. I was impressed cloth test. Great visual. I wondered about mine so pulled the EGR apart. It would only catch 50ml or so in 5K Kms, but the EGR is dry.. I guess different engines create more mist or less.. Thanks for subbing to the channel.. And thank for your content.. I know how much work goes into it..
@@jjsadv For sure, every vehicle and every engine would have specific requirements. Glad to hear that your vehicle is performing so well, definitely a cash saver there in terms of intake cleans. Cheers mate, I'm glad you are enjoying so of my content. Sure is a lot of work behind the scenes, but the appreciation from viewers is well worth it
So blocking the EGR will definitely prevent the build up within the intake. I probably wouldn't go the blanking plate with the 6mm hole, as it won't stop the issue it will only prolong it. You should be able to electronically disable or reduce the EGR and physically block it, which shouldn't cause any electronic codes or issues.
Stephen, mine has two valves. One to regulate crank case pressure in the side, as part of the outlet to air intake line, and one in the lid as a pressure relief valve, which vents to the engine bay. See these links below. Do you have a link to how the new ones work? I might have to get a new one...

@@Michael_Mears no links, but the filter has the pressure valve in the base that opens and let the excess go into the intake. My understanding that this was due to emission requirements not allowing ventilation to the atmosphere, so if a person does not replace or empty the filter, it all goes back into the engine.
Cheers mate, I'll look into that. The changes Wester Filters have made to their new 'IV' system would have to include increase emissions controls. Cheers, Nathan.
I recommend it for most varieties of turbo diesel 4WD's, including Toyota's 2.8L engine in the Fortuner. It will hopefully prevent the build up of carbon and give maximum efficiency for longer. Cheers, Nathan.
Look, you can vent with issue, however it’s going to make a mess, regardless of where you mount it and will deteriorate road conditions, particularly for other vehicles like motorbikes. I would recommend it, it’s fairly quick and easy to empty when required.
I heard that removing all the oil that goes back into the motor isn’t ideal as the motor does require it for lubrication. Not sure if that is true or not.
Jay Lee is correct, the oil would still have some lubrication properties and degrade along with regular engine use. Where the benefit comes from is eliminating the risk of condensation building within the piping and unit (primarily in cold climates). This creates a white 'sludge' in the catch can, which you definitely wouldn't want entering back into the oil feed of the engine.
Hey mate, its an option but given young your vehicle is and the fact that its only done 25k km, I probably wouldn't bother. Installing the catch can alone would assist though. Cheers, Nathan.
How important is pressure in the system? I have a homemade catch can (came with the vehicle) and it pretty much looses all pressure as it's far from air tight. How does that affect engine performance?
Chuck it in the bin, catch cans are preventing the valves and upper cylinder from being lubricated. If it's not sealed you'll be injesting dirt/dust etc into your engine. Throw it out, put it back to standard.
