since i have boosted my truck it seems to be bleeding some oil- there is oil under the truck only after i go and boost it- when i dont boost and just drive normal there is ver y very little residue under the

i beleive its because im boosting the crankcase- so i went and got a check valve from grainger to put into the PCV system to stop boosting the crank case- I just want to make sure this is it- I beleive it is comming out of the breather- on the valve cover all down the side of the block and causing it to burn off in traffic and look like my truck is smoking-

do you guys think that boosting the crank case is the main problem?

Yes, the air/fuel mixture is blowing past the rings right into the crankcase. The crankcase then gets pressurized and blows oil out the path of least resistance. There are crankcase evac kits, catch cans and air/oil separators out there to help combat this issue.

I've had the pleasure of going lean on my number 7 cylinder, so I get a quite a bit of blowby since those rings have seen better days. You're not alone with this issue. I've had oil blow out my dipstick and blow down on the exhaust manifold and onto the block. This proceeded to saturate my crank position sensor and it caused my truck to sputter, shut off and ultimatley not run. Bottom line, don't screw with leaking oil!

oil catch can. I mounted mine by the radiator, with one end going to the inlet side of the turbo(vacuum there) and the other side goes to my passenger side valve cover. since then i havent blown the dipstick out, LOL. I put a drain hose on it too

I miss this part of working for a race team, the crap I could make with the stuff we though away and all the fab tools at my disposal, some times I wonder why I left ... Oh ya, I remember, it was the 70+ hours work weeks and no social life!

Why do I see tranny cooler lines in that pic? I thought you were going with a T56.

You don't have any kind of filter or air/oil separator before the line enters the turbo? Just a catch can?
