Nice 👍 fun fact for us b6/b7 s4 4.2 owners , unlike the rs4 4.2 with direct fuel injection A.K.A Fsi ,that sprays directly into cylinder head , the s4 4.2 is a multi port injection which makes the fuel injector closer to the valves but still sprays in manifold. A oil catch can has been proven most beneficial for direct injection engines but any modified engine always produce more blow by so this device is a actual component to the pcv and aids in deposits being recycled. The valves closest to the path of pcv are common for the most deposit build up which are the intake valves. Also great job on your “DIY” using the stock Check valve to regulate the flow prevents cold start idle issues and too much crank case vacuum. some people like venting to atmosphere but I prefer to leave the pcv vented back through intake to create a vacuum inside valve cover/crankcase to remove blow by fumes at a consistent rate.
Totally agree. And thanks
Very helpfull.. i changed my pcv valve which i then found out it was bad i have 140k miles in it... i no longer burn a half a quart of oil evry week .. driving about 250 miles weekly.. its been a month and oil level has been same since pcv valve replacement and oil catch can installed..thank you lots for this video.
That's awesome! Happy to hear this video was of help to you
Good write up my guy ;)
Thanks
Niceee.....🤟🏼🤟🏼🤙🤙 Very clear information. 👍👍 I have a 05.5 b7 S4, looking to do this procedure.
Thanks. once you know who the flow goes it makes install a lot easier
Thankyou
Your welcome
I have the same can in my Benz but red to match.
Been thinking of upgrading the can
is 3ft 2x of 5/8 hose enough?
This all depends where you plan on placing the catch can. It's been a very long time since we've done this. I would just a any string and dona rough idea the path you want to take and measure the string and give your self an extra feet for insurance purposes
Mark- are you able to mount the catch can or does it just sit in that area loosely?
So for me the catch can actually fit nice and snug there. It wasn't loose at all moving around. I do believe it has to do with how long/short you cut the hoses. I left my hoses a lil longer just in case. And by them being long the hoses pushed the catch can into the corner, if that makes sense
@@markb6s4 perfect sense. Thanks Mark.
Can you do a video of a catch can on your Q7?
So I should route the hose to the catchcan then pcv then to intake? I had it pcv into catch can into intake manifold is that why I blew some seals?
Yes. You want the pcv valve your last resort of defense if that makes sense. The catch can should be in the front line of defense. As for the blowing of seals. I'm not sure If it was bc of that. Can you elaborate on what seals you are referring to?
@@markb6s4 it was a camshaft position sensor it started leaking and letting puffs of smoke out from the passenger side bank. Something was causing the crank case pressure to build up
My guess the pcv valve needs to be replaced. May have gotten clogged then didn't allow the gasses to pass then that creates pressure. I can be wrong. But from what you mentioned that's my guess.
@@markb6s4 I bought a cheap Amazon pcv valve since I believe my old one went bad.
@@EGEIS9 I've read about cheap pcv valves over OEM. And several have recommended to just go OEM / OE. Ingot my pcv valve from "fcpeuro" and you can beat life time guaranteed. I get alot of my parts from there. My pcv is OE, OE is the literally the same thing as OEM but they scratch off the Audi logo off and sell it for a cheaper price then OEM
Your supercharged now rite ?
Correct it's supercharged
@@markb6s4Can you please provide more information?
@@denniswvwwhat about the installation of the catch can do you need more information on?
Would this work the exact same on the 3.2L FSI v6?
I am not familiar with the V6. But if the layout looks the same as the V8 then i would imagine that it'll work the same way in the set up
what does this accomplish other than not allowing the oil back into intake?
It helps reduce carbon build up on the intake valves
@@markb6s4 Not necessary. It's not a direct injection engine.
B6 S4 wasn't FSI. I thought carbon build up was a FSI issue.
you are correct about the fsi getting carbon build up. but the b6s4 BHF still gets carbon build up but not as bad as a FSI. In the long run it helps all engines no matter what type it is to prevent oil getting into the manifold
@@markb6s4 thanks for the tip
is this s4 with turbo?
No. At the time of doing this video the car was n/a. The same set up will still be the same if you do a turbo or supercharger
