The Best catch can operation video Toyota Hilux Vigo diesel with a catch can after 50,000 km Does a catch can work to stop anything in the EGR system Is a catch can connected to the EGR system Fourby4diesel 
It’s rather simple, block off EGR and install a catch can you get a clean motor, the PCV and EGR recirculate contaminates being oil vapour and exhaust gas, modern day cars with direct injection experience more carbon and crud buildup because the direct injection doesn’t spray fuel past the valves like a carby or port injection, there is nothing to clean them therefore it builds up.. To the people in the comments that have removed their catch can and think their car runs better, it probably does but this is likely from poor maintenance, a blocked PCV or catch can will make the car run poorly because it can’t ventilate the excess pressure, it will also cause oil leaks because the crankcase is pressurised.
Hi mate, thanks for the explanation and providing the right information without messing around. I have a Gu patrol and installed a catch can 40k ago and since I installed I could see that more pressure was added to the valve cover and some oil started to come out from the injectors sealing. I just removed the Catch can and see how it goes now. I am also planning to install n the coming days the plate with 7mm opening to restrict the recirculation exhaust gasses through the EGR. Once again thanks for sharing sash a valuable information.
thankyou, someone in the industry (who I do respect) telling the truth and how it is about catch cans, I get in so many arguments with customers when I wont recommend to install them, but if you really have to have one you supply it and I will fit for you,
You raise a good point about diesel motors maybe not needing one, but on gas engines they are helpful. Many new gas engines don't even have an EGR so the oil vapour comes from the rocker cover and just goes into the throttle body and coats the valves.
I've got a good one for prado 120 1kdf and others, fluid levels and oil levels, the importance of being correct and the bad of either over filled or under filled.
Hm. Currently on the fence for a provent... glad I found this... so yay or nay for a catch can for my Hilux N80 with 24k kms? It costs a bunch to get it shipped from aus to borneo
Thanks for this information. I will definitely check the playlist. I'm glad I haven't put the money down for a Provent catch can. I'm really disappointed in the unfortunate truth that I have discovered.
Yes great. Now disconect the EGR. Now your engine will breath easer the blowby is not messing up the combustion or the air fuel ratio a good clean burn.
I got such a catch can, Provent 200, installed on my 2005 Freelander TD4, with the BMW M47 engine. It seems to work very good, intake of the can is wet and got carbon chunks, output is bone dry. In my opinion top pros are dry intercooler, which makes it more efficient, since oil is reducing its cooling effect, dry deposits on the intake, the less oil, the less deposits. As on the exhaust manifold, a thin layer of carbon that doesn’t thicken. The cons are mostly related to wrong installation. On the other hand you pointed out very good that the oil that gets past the catch can continues to grow deposits. But this is related to the efficiency of the filter inside the can. Lastly, about the abrasive particles from the EGR I don’t think the intake valves nor their seats will suffer damage, as there is no damage on the exhaust valves anyway, which, guess, they are always in contact with those particles. Anyway thank you for the video and I hope you respond with your opinion about my arguments
I own that same engine on my 320d e46 and I was wondering about buying one of those catch can and leave the EGR working. But many things I found about people installing these catch cans is that the seals of the engine gets damaged earlier because of the restriction you add with the catch can and this pressure been released through the seals. If you can give me an opinion about that it would be great. Thanks in advance. Cheers.
@@Adrian-re9fh Thank you for your question! Provent 200 causes little to no restriction as its flow goes up to 200 litres of blow by per minute. Any damage that appears after the catch can installation can only be the cause of a wrong installation or not servicing it. Servicing means draining it whenever drain tube gets full of oil and changing the filter after it gets completely soaked up in oil (perhaps after 25000-30000 km). I’ve had the catch can on my car for 10000 km at least and caught about 200-250 ml of oil ever since
@@04rodeorider75 Thank you! Be aware the Chinese copies can only work as good if you add the genuine Mann filter insert; the steel mesh makes only the impression it works By the way, instead of a reply I was notified about another anti-catch can video with the exact same philosophy😅
catchcan is useless. delete the stupid egr to get rid of soot. the crankcase vent system lubricates the intake valves and turbo. I’ve used this catchcan on my mercedes sprinter v6 and nothing but problems and noxious fumes from it. That filter is another maintenance item that gets trashed quick and is expensive. Plus you loose some energy content for combustion that are wasted via blow by that would be burned otherwise and provide more complete burn off of all emissions. With can catch can you’re mostly burning the light vapor fumes and the heavy oil drops out. The moisture won’t be an issue because it has oil mixed in and won’t cause corrosion on ferrous components. The bigger the crankcase vent hose is to the turbo, the less crankcase pressure and less drag as well as crankcase gases will be reduced which at first glance seems counter intuitive. Emission is just an automotive engineering hypocrisy exercise. There are no solutions for emissions, only trade offs. Making cats and dpfs creates pollution at the factories that make them and mining companies that mine them. It’s not lower emissions just more hidden emissions. The electric car supply chain is even worse with all the copper heavy manufacturing. The green movement is definitely doing the opposite while virtue signaling. More money more money more money is all they want while lying through their teeth. A deleted truck is the greenest when properly tuned. A lot of extra parts will disappear and yes, less pollution because of less manufacturing. Our world is so backwards
As a mechanic I 100%agree with u. If its really necessary why wouldn't those big 4×4 manufacturers put in 1st place. Better to spend money on schedule servicing and better fuel refill
Why don’t manufacturers include them? lol because they don’t give a F&@% about the long term (past warranty) condition of your engine nor your long term maintenance/repair costs, nor your long term efficiency. And they don’t trust the average owner to empty the can even if they (the manufacturer) wanted to spend the extra $ on the device. They want to keep selling vehicles, it’s all about planned obsolescence. Look how much cheap plastic and low quality metal is used in new vehicles. Look how difficult it is to service anything in the engine compartment, the designs favor the dealerships, the mechanics; and the parts suppliers. As consumers we are just the trees that grow the money for the industry.
a catch can is good for some cars and not for others, On cars that do NOT need a catch can, have the Crankcase ventilation pipe going straight to the inlet manifold therefore avoiding all the rest of the intake system.. Cars that need or could benefit from a catch can are the ones that have the crankcase ventilation pipe going straight to the air inlet pipe which then travels through the intake, the turbo, the intercooler and the intake manifold including all piping. The ones that go straight to the intake manifold are basically cleaned because they are so close to the injectors.
Remember the days when crankcase gasses was expelled onto the road and not through the air intake? I don't think engines wore out quicker if regular oil changes were followed. In fact I think most engine problems started when the emission laws required the crankcase gasses to be burnt off through the combustion process.
Cheers for the video mate, makes a lot of sense, and it helped my decision greatly. Have been tossing over getting a Catch Can on my 2020 MU-X for months, { currently only done 35.000 klms } you put forward a good argument. I service my vehicle by the book, and generally trade my vehicles in around 150,000 + Klms, so the engine should be in top shape anyway The more I look into it the more I'm convinced a Catch Can may be futile. Question....my service department suggests having the EGR valve cleaned next service, for about $100...do you think this may be a good idea ?
And what happens if the recirculation intake comimg from pcv to the air intake is before air filter?, would soak the air filter with oil but would not pass further dont you think?
I know a few lads that have had catch cans fitted and they have ended up taking them back off . my next move is a reduced flow EGR plate that's where the problem is .
@@Fourby4Diesel catch cans ended up causing problems for them like increased crank case pressure and it think caused leaks for my mate mark who owns a car breakers business and knows a thing or two about motors like your self ,so catch cans for me are bull shit don't go there 🤣.
Seems that it is a serviceable item that needs to be done as and when required. Maintenance maintenance maintenance is the answer to keeping your investment running nicely. Just do it!!
Great video mate, always love two sides to the argument. And couldn’t agree more with BS out there and bad advice. Couple of questions for you though. Do you think weather plays apart? I’ve got a provent and in winter it’s producing double the amount of oil in the same amount of time with the same driving style. Do you think the hotter weather in summer creates a better burn?
You'll never stop the soot from the egr building up so no point trying just clean the intake every 100k, iv a catch can on my new ranger to protect the turbos and intercooler and a snorkel for clean cool air 😊
I was about to buy a CC, but wait, dont thinks its still such a good ideea. Thanks mate. I have watched most of your videos regarding the injectors, and you really cover all the aspects, but I am still a bit confuse, is the 2014 Hilux 2.5 d4d with craking pistons issue ? Mine is 2014, 220k on the clock, and all the reading ( dead cold/hot ) are 0.4 -0.2 -0.8(cyl nr 3 ) 0.0. Thanks again,
Depends what you drive. Gas engine with direct injection needs a CC. I have removed my EGR as well. A guy can also block it off with a prefab sheet metal like the gasket with no hole in it. I have clean valves and have for over 40k miles. If you are in a emission state/country, you can just remove the block and put back to stock for your inspection
I fitted a catch can to my vehicle at around 20k, when I sold it at around 120k there was nothing more than a thin film of oil in it, I never emptied it once in 100k of driving. I also fitted an EGR blank plate at the same time and when I sold the car the inlet was still clean. My new Prado I have fitted an electronic EGR cutoff module, I won’t waste money and space under the bonnet fitting a catch can.
It's about contaminants being put into your very finely metered air-fuel ratio to give the cleanest most efficient combustion in the combustion chamber. Then you add all that soot and dirty gooie air to increase the carbon in the combustion chamber that goes into the crankcase causing premature wear on all moving parts as well as less HP because of poor combustion in the combustion chamber compounding it with each cycle having some kind of collection system to prevent this must be an overall improvement. But venting directly into the atmosphere or reburning the same contaminants doesn't seem to make sense. It just seems to create more carbon build-up lowering the longevity of the engine
In the 60's/79's we used to go through great pain to polish our intake ports from V8's to my slightly modified MG with 2" twin carb and a light lump in the cam. Fun little car. My V8's were more fun😂❤
Who said to run a 1gd I said stick with the 1KD last of the best No plate needed just sell the car before it runs out of warranty its pre 2020 Then that’s really bad just sell it or take it to the Wreckers
Showing the inside of an EGR valve has nothing to do with with the efficacy of a catch can in PCV system- They are separate circuits. The EGR valve and body has carbon deposits from the exhaust, not the crank case.
Got to admit I also was thinking why on earth is he showing the inside of the EGR valve when would be exactly the same can or no can And to say minimal oil goes through is nonsense. After 10k of pulling a caravan I drained more than a cup full of oil from the catch can on my Prado.
I thought you're only supposed to use a catchcan in high powered applications. For a stock engine theres literally no point in a catch can unless you have insane blowby
Hi Jacob. I have to say that's incorrect. I fitted a catch can to my 2020 Colorado at 6 thousand kms. After being driven sensibly on bitumen for 5 thousand kms I drained it and wad absolutely surprised by the amount of oil and water that had accumulated. A wise investment indeed.
@@Fourby4Diesel , I presume the guy means “oily vapour” that passes down to the crankcase via the piston rings on the combustion stroke, combustion probably creates “soot” too, if you agree, that finds its way with the oily vapour to the crankcase. If a CC collects that combination, good, rather than recirculate back through the turbo and intake. I rather like the idea of cleaner air entering my turbo.
So of you had to pick (and legality wasnt an issue) would you Completely block the EGR system with a plate Partially block with a reduced flow plate Electronically disable EGR Leave stock and clean intakes regularly
why don't car manufacturers just take the exhaust gas after the DPF?, so there is minimal soot feed into the egr and intake to start with...., my view is if they are too lazy to design a clean-ish exhaust gas for EGR, then block it off at early klm's, with optional catch can...DPF diesels been around a long time now and there is zero excuse for lazy car designers who design sh*t systems....
Simple, just delete the whole EGR system and still throw on the catch can as well then right? Or will captain planet come and kick you in the nuts. Iv looked at my 2 TD27's intake manifold/valves side by side, one with EGR delete and one without and the difference was staggering
Do not use any catch cans. What people NEED to do is learn how to measure the crankcase pressure. Its funny they know how to check tire pressure, fuel pressure, boost pressure, coolant pressure, oil pressure, transmission pressure, etc... but nobody is measuring the crankcase pressure. High crankcase pressure causes pressure scalar gradient forcing oil out of the engine and into oil seals including piston rings. I have a DIY Video in my channel how to measure crankcase pressure using 1-bar map sensor and 5-volt source so you can check your engine and adjust as needed. Little bit of thinking to do on the deposits and features of deposits. Blow-by is essentially exhaust and it mixes with some oil if there is oil drawn along with it. High crankcase pressure causes large oil droplets and high oil droplet density to form. It takes energy to drive fluids through hoses and hoses add friction so the PCV system should have short as possible hoses with small enough diameter to enable high velocity high temperature fluids to return to whence they came. Think about that for a minute- The combustion process occurs and some slips out into the crankcase, if we could return it to the cylinder instantly it would not leave any deposits and will not interact with engine oil. Think. Carefully. Imagine the blow-by gas leaving the combustion chamber working its way down through the rings or into the exhaust and being sucked up and returned to the cylinder where it was a moment ago. No harm done. The harm is when the blow-by gas is allowed to cool down, condense, slow down, due to insufficient energy supplied via PCV action (pressure below atmospheric to drive fluid evacuation). This is why we measure the crankcase pressure and design the PCV system and engine modifications to rapidly evacuate the blow-by and return to the cylinder immediately. Do not allow blow-by to circulate into engine oil where it will leave deposits and cause eventual wear and failure.
What's the cost of cleaning out the intake at 100,000km? I'd much rather budget for that and leave the engine as designed than mess around with a catch can. What's the loss in performance? I haven't seen any crazy blockages that would have me too concerned.
I'm on the fence regarding catch cans and even air / oil separators. In my opinion, the solution to all that carbon build up is Walnut Blasting the intake chambers and valves.
There is a way to clean the inside Body of this unit is spray with carburetor or injection cleaner & also you could use longer drill extension & have a wire brush & will clean that up nicely & once you have pretty nicely clean spray inside the intake unit again with carburetor or injection cleaner & that will get rid of a lot broken deposits & then go with a clean rag & that should clean that up nicely & will look like New again & talking about oil catch cans & I'm going to have to get one for the PT Cruiser that my wife owns & it has been a nightmare this car & I do regular oil changers on this 2 liter engine & have changed the coil & leads as the coil came with & also had to change the Champion Spark Plugs & even though they Iridium Spark Plugs they were stuffed & these Bloody Champion Iridium Spark plugs were put in by Bloody Fucken Mechanics Work shop when they did the Cambelt change & I didn't know that they were Champion Iridium Spark plugs & my said to me that they were special spark went into this engine & when noticed that they Champion Spark plugs & that they were Iridium Spark Plugs & they had black rings around the Chinas on all 4 spark plugs & I threw away & bloody good as the engine wouldn't run properly & I brought NGK Iridium Spark Plugs once I installed them the entire engine ran a hell of a lot better & they are the Bloody Best Spark Plugs that you can get & I still did have a slight miss in the engine & I pulled sum of the sensors plug off & sprayed them with WD40 & one of the plugs off from the valve body & before I took it off I noticed the clip that holds the plug on properly was broken bugger & was held on by a cable tie & who the broke that I don't Bloody well know & well anyway when I took that plug off & sprayed that plug connections & inside the connectors where that goes into it put the plug back in place & I then closed the bonnet & went for a drive & put the accelerator hard down no more miss & solved the problem & I'm not a qualified Mechanic & yet I solved the really bad miss it had developed but now I have a blow by problem & yet the motor runs really well to but when I took off the intake manifold off when I did change the coil & leads & later when I changed the spark plugs I noticed a lot of oil it the intake Ports & wipe them up with a clean rag & later on when took the top off the air box off to check the air filter I got a shock the air filter was covered in oil &.I had changed that air filter a long time back & so I had to take the whole air box off to clean the oil out of the air box & what a mission that was & so I checked the engine oil level & that was on the low mark & the breather hose I cut in it half & added a a breather unit to them but what was happening the oil was coming out of the 2 breather units & so now I have to install a oil catch can to solve the oil issue & having it installed by a qualified mechanic the oil catch can is a Ryco Oil Catch Can A RCC351K Crankcase Filter Kit & Tony found that I had a PT Cruiser ignition switch problem & needs a new ignition switch but can't get one in New Zealand & the Chrysler Dealers don't have one in New Zealand at all which is a bugger & Tony is going to see if he can fix the Ignition Switch & hopefully he can fix it & I have been having High AMP drop as well & the battery can go flat over night if I dont lift up the fuse for the interior light system as well as the stereo system & the heater so it must be the Ignition Switch Problem that is causing the massive Amp drop that I have & I don't have money to replace the engine & already spent money on 2 tyres & its going to cost me even more money on a Ryco Oil Catch Can to solve the blow by problem & had been a good realiable car & now its starting to cost money Kind Regards Peter
So I recently removed a catch can, installed at 200k and removed at 350k on a 2010 Prado. So what they don’t tell you, is that the filter in catch can needs to be changed. It’s actually hard to remember or for the mechanic to remember to empty the catch can. Which means it was probably doing more harm than good. After removing it, less smoky exhaust and I swear the car drives smoother and is more responsive. Save your money and install an arb on-board compressor. Much more usefulz
That’s ridiculous! You basically said you are lazy. Of course it’s not going to work if you can’t be bothered maintaining it! Don’t give people bad advice!
So you only change your engine oil filter because someone told you to do it? Of course the filter in the catch can needs to be changed.. any filter in any application will need to be changed at some point… you literally just described having a blocked catch can from poor maintenance.. the car drove smoother and was more responsive because you allowed the engine to breathe again, you are allowing it to ventilate the pressure which will free up a few horse power..
