Crankcase Ventilation Mod w/Pics
#241
from this whole thread, this seems to be the most legitimate and easiest way of taking care of this. I think a lot of people are/have read this thread in search for the... should i say, best, or most effective way of taking care of the problem. If there's one thing this thread is lacking, its a general consensus on whats right. In my opinion, this diagram seems effective. anyone want to confirm this for the other users that may be mind boggled by this thread?

ok so you blocked off the plenum port then it sounds like. meaning, (in stock form) the pvc feeds to the plenum port. that one. correct?

Tom, that looks awesome! Work of art!
Chris, with that set up I would get soot on start up - two streaks behind the car. No smoking though. I don't know why but it doesn't happen anymore with my current setup. Perhaps because there is no crankcase ventilation on start up or shut down since no strong vacuum hook up at idle.
Dean, that diagram is a set up is what I found works well after experimenting with many different configurations. I don't know if it's the best way for everybody, but it's worked out well for me.

i cant believe this thread is still goin on... LOL something this simple shouldnt need 245 posts.
Toms is setup exactly like Chris@fsp, except he has both valve covers going to the catch can.. Thats as simple as it gets. No reason to do anything more complicated.

I finally got around to changing my catch can set up. i took some pictures for you all just for the hell of it. I had a HUGE smoking problem after ANY pulls. noticed an immediate fix for the problem with doing it this way. sounds weird but the car runs smoother than before. the blue cylinders are one way valves. i drilled the PCV also.

update.
i sucked a TON of oil into my catch can within a day. it worked at stopping my massive smoking problem after a long WOT pull but now im overfilling my catch can fast. im going to try plugging the manifold vacuum source and intake pipe source and see what happens. so essentially i'll have a drilled pcv and it running to the catch can and a breather on the other port of the catch can. thoughts?

Mine is just vented to atmosphere (2 breathers).
We're guessing on mine that most of my smoking was fixed by putting the vent off the sump tank to the catch can more than the from the valve covers. Before mine would just build up oil pressure in that tank after the turbos...when you let off the oil pressure was still there and pushed oil back through the turbos (gotta go somewhere) and caused the smoking. Now its all clean, no smoke what-so ever.

Put a breather on the driver's side rear port and your oil collection will reduce by an order of magnitude. The vacuum set up you have will preferentially pull in fresh air vs heavy oil saturated vapors. I think this is preferable to just having open breathers with no vacuum, but that works also.

update: i tried venting the drivers side rear port to atmosphere (previously it was still connected to the turbo inlet tube) and im still filling oil into my catch can way too fast. so now im going to try plugging the manifold and removing the suction from my intake pipe. so essentially it'll just be a drilled and vented pcv and breather on the rear drivers side port. lets see if this does the trick.....

final update
i rerouted the lines just like thom000001 has his. no more smoking after a WOT pull and im not sucking tons of oil into my catchcan anymore.
just an fyi for those of you who may be having my same problem.
