so let me get this straight, your running oth the krank vent and the PCV valve...? stop that. one is a replacement for the other, not an "ok, we'll run both" thing.

do you have it plumbed inline, or in a "y"?

The PCV valve, and the krank vent are the same thing, just a dumb check valve. one is cheap plastic, and the other is suppose to be a better metal equvilant with precision manufacturing which will hold back more boost for cars running more than 15 - 18 psi.

so if you hook it up:

|intake tube| ------ |PCV valve --->| ------ |krank vent ---->| ------ |valve cover|

It's like running two oil filters. which some poeple would say is good because you getting extra filtration, but others would say is bad because you may be dropping oil pressure to much across both. but back to your thing.

you now have to have BOTH check valves working properly for the system to function. if one or the other is stuck, you car will blow oil on decel.

so first. take one or the other out.

if your running them in a "y", show me how, because I'm not gonna guess.

next.

the puddle. any stains on the back of the engine? Did you re-use/leave the oil return line in the back turbo alone?

could be a leaking oil return line which drips on the exhaust? that should make smoke any time the rpms are up though.

I would also think that the VSS would leak any time the oil pressure is high enough to push oil past the bad seal, or any time the RPM is up.

Your problem sounds like the PCV valve/system is not working, your pressurizing the crankcase/valve covers, and it's blowing oil past the rings, which is running it through the engine, and out the tailpipe...

but the leak adds new dimensions... sooOOoooo

do step one. then check back.

It's coming out the exhaust and inside the engine bay? This is unusual to say the least. And only after you let off from boosting?

I believe the oil all over the valve cover was a horrible stock oil cap, I threw on an aftermarket one with a good oring and it didn't seem to blow like it did before.

So are you saying it leaked but not as bad?

Theres a film around the bottom of the cap, its nothing like before, it could be residual from the other cap. I need to really clean that area and drive it again since I made some changes to the PCV system.

Something else I did was remove that large rear valve cover krank vent and replace that whole tube to the 'bubble' with some clear tubing. I would figure if I was building up so much pressure in the crank case I'd see SOMETHING inside that tube. Pipe is perfectly clear still, no signs of oil, or visible film on the inside walls.

Anyone else confused or is it just me?

That sounds normal.



I'd be careful with that clear tubing. Some of it is crap and won't stand up to the oil itself. It can then breakdown or collapse.

I think I may have had my one directional arrows backwards. I'd have to look at the car to tell you yeah or nay. It's to easy to get it backwards when your just internet-jockeying.

just wanted to say that...

Are you talking about the Krank Vents with the huge red arrows?

Are you talking about the Krank Vents with the huge red arrows?

Both turbos', first two are the front, second two are the rear.

These were taken about 4 day's after its been drivin, I probably need to start it up and get it to smoke and take some pics again to really get some descent results.
