How To Install A Catch Can 

IT makes life so much easier LOL

Thanks so much Tim 🙏

That's was my question how does the intake side of the turbo provide a good enough vaccum? Or do they even meed vacum to ventilate the pcv. Old cars vented it to atmosphere I believe it only is under vaccum since they had to reroute it back into the combustion chamber for emissions purposes only

HAHA, never thought about it that way, but it sure is

+Luke Edward hahaha I watched The Matrix last night so I feel ya. Lol

Wish he would say.

@@hunter6099 sameeee....

thanks Charles, will be waiting for that other video, maybe you should add an extra question to the list : why cars don't come with catch can from the factory ?

HumbleMechanic never believed in these, plus the ea888 has a built in catch can. That is what the block mounted (under the water pump) oil separation valve is for.

The last Q is easy. COST! but it's a good point to bring up in video

That is the primary oil separator. That gets the big particles. The fine oil separator is built into the PCV valve.

I see.. well.... just thinking load... I guess cost may not be an issue for German manufacturers, they sell expensive cars anyway, at least it should be available as an option for some engines...

+Rob Rice yikes! Do you find t still worth having? I'm in NC so it's not an issue

HumbleMechanic : before two blown seals, each on separate occasions, I thought I was doing my engine good, every time I drained the sludge out of the can. But after the 2nd self inflicted wound, I ended up selling the vehicle. After my experience my take away is this: We all want what's best for our engines,, and want the most longevity out of them. Now in a new vehicle, I have to ask my self, how many more miles will a catch can add to my engine life? My answer: probably negligible and not worth the cost and hassle of draining the can. It's funny, on my past vehicle, I was always looking for reasons to tinker, modify, and make "improvements" with mods. And after burning my self, I reason towards leaving things stock. As long as you can justify the "need" for a catch can and how it applies to your situation. Of course it's worth it, your helping your engine breath healthy 👌

WOW a well written, well thought out comment on RU-vid from someone that has experience and knowledge of the situation??? Can it be?? HAHAHAHH Thank you for the insight Rob! I am doing a video on how catch cans work for next week. I Will be sure to mention that. THANK YOU!

I've thought about blocking off the inlet right at the turbo and just putting a air filter on the "return" pipe of the catch can, do you think that would have solved the problem you are describing here?

Rob Rice in

From all videos about catch cans I've watched, this is the only comment that made me even think about that. Maybe i shouldn't install one living in Boston?...

@@KamotoSam I suppose you can get away with it. But be sure to install it somewhere where safe and keep a lookout for starters for sure. To be honest I'd stay away from it if driven in cold climate. Here in Finland I've heard horror stories of frozen breathers quite many times.

@@jothain yeah thank you for the comment seriously. I'm probably gonna hold off to install one till spring get used to having one before winter

@@KamotoSam Might be better and thank you for nice input yourself 🙂

I was thinking the same thing, that wouldn't it be easier to just come out of the PCV go into the can and then go back into the intake connection then re looking at the video it came to me when looking at replacing the PCV assembly at the same time, it looks like unlike traditional single line PVC systems (SB Chevy off the valve cover into the air cleaner) there is 2 exits for this assembly, the one in the front that goes to the intake manifold and the one in the back that goes in the intake run just before the turbo entrance so its looks like VW is putting crankcase gasses in both areas. I agree that you would have less vacuum at the turbo intake but for the purpose of reducing the material that is gumming up the intake valves you would need to direct both PCV exits to the can. At slower speeds and idle is when the most blow by gasses are produced, the intake vacuum is much higher at idle than the crankcase pressure and it pulls the gasses into the cylinders to be burnt, when the car speeds up and the PCV valve will close as the pressure inside the intake manifold increases to a positive pressure to prevent a reverse flow of pressure into the crankcase, but at higher speeds the combustion process is much more efficient but there may still be some gasses that need to be vented, of course at speed with the high volume of air passing into the intake the velocity increases and the pressure decreases in the big intake tube, effectively creating a decent vacuum that pulls the air thru the system. In fact now that I think about it the high vacuum at idle at slow speeds in the intake manifold may actually cause to much flow thru the can preventing the separation of the oil and gasses. I did notice with this kit it is effectively blocking not only the intake manifold but the 2nd exit of the PVC value that enters and turning it into a traditional single line PCV system, just like the old SB Chevy PCV going from the valve cover to the air cleaner

Sweet!

HumbleMechanic Hello ,sure am learning from you about diesel motors, I just purchased a used 2014 2.0 tdi, really a 2013 comfortline package, has 68000 k local Volkswagen dealer here in Ottawa Canada. Bought certificate , put the Mechanical breakdown protection plan for 3 years or till 147,829 k. Would like to keep it for life ,I’m a back yard mechanic, haven’t done diesel, but I would like to learn tricks and practice at junk yards, and collect parts. About putting a catch can on this,and what the Dealer will say thanks

I agree, this install had me scratching my head, however it 'can' be done this way as the PCV side can be seen as a check valve, in that if there is more pressure in the crankcase than the outlet (in this case the inlet side of the turbo) then it will allow flow. That said this is typically restricted flow to prevent excessive scavenging and low load running quality issues. As such this is not the port you would want to use for a singular crankcase breather... not a good setup black forrest.

You are overlooking the obvious... where does the oil found on the charged comes from? if you say that is the clean side. Did you notice the oil residue on the intake pipe when he was installing the new 90 bend coupler? Yes, you do need an intake side can!

Bro, habla en ingles el chabon, si me vas a contestar que puede usar el traductor, tambien vos ;) y no hay otros catch que no anulan todo.

Hi Charles, i´m stay in argentina, thanks for your videos!! My question is this: our cars with TSI motors 2.0T FSI o TSI 2nd gen, have 2 ways out of blowby vapors??? one way is top end in PCV stock. and the other way? the previous version of TFSI have one PCV in block right? please see that picture and aswer me, sorry my english is too bad :( goo.gl/iJgoPi

But think about it the front pcv outlet had a check valve in it so on factory the front hose running to intake manifold once in boost the check valve stops air from going back into the pcv outlet therefore the front one only works when idling so the main vacuum when driving which u do more comes from the cold air intake side before the turbo where the new hose will hook to an ur right not have as much vaccum like from the intake manifold, but that's all the vaccum it gets when driving anyhow an only when idling does it get the good -21 or -22 vacuum.. hope that makes sense lol.

1) youd be an asshole to do that knowningly polluting everywhere you drive. 2) the system is designed to be sealed and have a vacuum on it, leaving it open would decrease performance.

BoogieDownProduction him and the rest of the older vehicles that have them vent to the atmosphere. If he chooses to do that he can. Just know that yes you will be polluting

@@Wakko0o Like I said modern vehicles are a vacuum setup so if he vents it he will be an asshole for polluting but will also get worst performance. its not the same design as old cars.

BoogieDownProduction makes perfect sense good to know thank you

Tro Rt it is direct injection fuel cleaner does nothing unless you spray it directly in to the manifold via a open hose or port

I will be doing the Seafoam treatment next week. The problem is, these tests are almost impossible to do. You would have to track a car over a period of 50k miles with and 50k with out. Then you still can't be sure the variables are the same. I would love to do it, but I simply don't know how to actually do that

I’m doing this now on my golf R. It’s a longer term test

Yeah, I will top it off at some point LOL

I didn't forget. This is strictly a DIY video. I am going to do that video in the next few days. I have played around a lot with DIY only VS DIY and description. It usually works that the videos both better broken up.

Good day. Can you please advise how much oil are you collecting?

Andreas Andriopoulos around 150ml per 100km (60mi).

Sir, thank you for your your reply. Noted

Did you install it exactly the way Charles did it?

See I'm curious of why some use the back outlet as others use the front outlet as well. An why they dont just tee both into the same hose

If you go to the official Black Forest Industries website and look for the catch can kit from this video, you'll find photos of it already installed showing this same setup. So I guess ECS Tuning's catch can system works differently.

They might. The issue is the oil is highly aerated at this point. You wouldn't want that back in the oil sump

HumbleMechanic I meant draining it back into the oil sump via a valve on a regular basis, such as during an oil change.

That could work. I mean that is how the OEM designed the system LOL.

Austin Allmond you really wouldn't want to do that since it's not just oil you are catching, you are also catching water vapor and fuel vapor.

Thank you. 💙

Hi Michael from England, what.is egr system?

A egr is a exhaust gas recirculation valve, to help with emissions control. Hope this helps?

Only the front pcv outlet has a check valve the back one doesn't. So with it being ran PVC to catch can to air intake side if turbo it will have consistent vaccum. Not much but constant. If he had routed it back to the intake manifold it would have had vaccum under idle but when in boost it would have closed off the check valve like u said it would..

I want to know if better to close it or put breather

That'd be highly illegal and fail inspection in most states, but for 364 days a year, sure, you could.

On this application I was able to(I am 95% sure) Some you can't use the cover

LOL, I don't really see this being a option for the masses. adding costs to production and maintenance are scary for OEMs LOL

HumbleMechanic the masses would ignore the maintenance anyways...got a gal that is wondering why she can't ignore a no oil situation...she can't believe she needs an engine...uggg

One last thought..the oem' s pushed blue def on us. Why not catch cans...just saying 😆

+Javier Rocha The OEMs received the SCR as part of a third party emissions compliance package solution that was approved by multiple national compliance agencies, BlueDEF is just a consumable diesel emissions fluid to get the SCR system to operate properly reducing exhaust emissions. In short, the SCR and DEF was the least cost option for the OEMs to be emissions compliant.

Ha, ha, ha, ha. Never gonna happen. They are in the business of selling cars. Not making them last longer.

Anything is possible, I personally haven't seen one do that

Thanks for the reply and by the way, Love your videos. If I may explain, I’ve had the 034 catchcan in the past, hadn’t had any issues to my knowledge. the catch can I have on now is the newer ECS tuning ones where it works in conjunction with the PCV, if I remember correctly, the hoses route to the turbo cold side and One side of the PCV. (Different to the 034, where it deletes the PCV) The car now is at 77,000mi. Coincidently the rocker cover gasket started leaking oil shortly after install. Which I had fixed. However this white smoke symptom is almost like a faulty valve stem seal (where it only happens sometimes, especially at idle at a long time, but never whilst driving or when the engine is warm) but the only difference is that I heard valve seals happen more frequent between stop and go, deceleration and every start up. I haven’t had it tested but my local mechanic thinks it could perhaps be the pressure of this catchcan that caused the gasket and possibly the smoke, they beleive that this style that routes to the turbo may induce higher crank case pressure than the 034 design. The only way I guess I can find out myself without testing is taking it off and re-plumbing the old PCV hoses back In? (Which is a bit of a hassle and I can’t find two OEM bolts) Or is there an easier way at the mechanics without Taking this off?

I never made a Tiguan play list since I only did a few videos on it

Question, What Engine type is your wife's 2015 Tiguan, as will all Tiguan for the America's, there are made in Mexico. I'm seeing if this Catch Can from Black Forest will work. I would have to import it as shipping here is a bear. Thank you. David with a great 2018 SE Tiguan

Just wondering if you have it a shot with a universal can?
