Well I usually can figure most of this shit out but right now I'm clueless. My car has been smoking on start up and after you drive it a while it goes away (mostly) I bought the turbo with known shaft play (little side to side, and little in and out) The valve seals are fine and the compression is 150 across the board, although the valve cover I put on has all the baffling taken out of it and I'm running the hose from the valve cover to the intake manifold...do you think it's possible that because the baffling is taken out the oil vapors are going into my intake manifold causing it to smoke Help me out guys Thanks Travis

There's a very good chance that's whats going on. Without the baffling, the intake manifold could be sucking quite a bit of oil through the PCV valve. Is it worse during high vacuum situations?

Is it worse during high vacuum situations? yeah...only at idle it smokes, or like when i let off...same with just cruising down the road out of boost...they'll be spurts of oil coming out of the exhaust...if i go into boost the smoke goes away, that's why i was leaning towards the turbo not being the problem

That's probably it then. Any time you see full vacuum, you're just sucking oil inbto your intake manifold and burning it in the cylinders. Put the baffling back in and you'll be fine.

Put the baffling back in and you'll be fine. the car is gonna pull a lot of vacuum on startup am i correct? I could just take the line off of the intake manifold and block it off and run the oil vapors into catch can couldn't i?

You could but you really want those baffles to stop as much oil as possible from exiting the engine.

Alright, I have a shitty cracked VC...i'm going to pull the one off of my car and swap out the baffles and cross my fingers that it helps...i'm sure it's going to smoke a little after i do this because of all the oil that's probably in the intake still. Thanks guys
