Oil Burning Problems and ?s
i have just recently replaced my turbo with a used VF22. i never had oil smoke coming out of the exhaust for the first 2 or so weeks, now it just blow the smoke out and the car will stall at a stop light and becomes hard to crank.
Mods:
Intake
Gruppe-s Header
HKS uppipe
VF22
HKS downpipe
HKS CF/Ti exhaust
STi injectors
TXS Unichip
i was monitoring EGT and they never got above 700 deg C. it would never reach full boost in first gear it was set at 18psi but in first gear would only hit 14psi.
I have pulled the IC and there was some oil but not a ton of it. the oil i cant see that it is leaking from any where, doesn't seem to be.
the hoses that connect and run along the front of the IC have some brownish looking gunk in them and see that they go back into the block but don't know what there function is and what fluid it is that they carry. i cranked the car while it was cold the with those hoses unconnected just blew and oil like smoke out of them.
I'm thinking i need to do a compression test. I also think the oil seals on the turbo are gone? i have no idea what is wrong or how to fix it, any help is needed and thanks in advance.
Thanks

Ah yes.. yet again I am a grave-digger.. digging up old, dead posts.
First off.. does your 22 spike/boost creep or go over that 18psi setting? What is your boost control? What engine management? Also.. did you use the stock wastegate hoses from the stock turbo or did hoses come on the 22? -- those first questions are to try to help my spiking problem.. the following comments are in response to your problem(s).
Is the oil line torqued down properly? Have you changed your pcv valve recently?
Is it burning oil, a little, or is it consuming it, a lot.
I had the same issue with my p/p td04.. thats why I went with the 22.. I still get oil smells etc.. but I don't see any smoke, I guess all the blowby is goin to the catch can where it belongs.
Also, look right before the turbo inlet (between the inlet pipe and the turbo itself) is there built up gunk/oil/grease? Is there grease in between the two piece of the turbo near the clamp? I know for the fact that the stock turbo inlet hose is junk, mine fell apart on me @ 57,000 miles. A hole literally developed in the top of it and it was spewing oil everywhere. Then again, I did have a ton of blowby for some ungodly reason (the seals were shot on the turbo, when it took it off there was sludge coming out of the exhaust side, pretty "redonkulous"). Anywho, I did a compression test.. it came out alright.. 155 1, 3, 4, 154 cylinder 2..
So err.. yeah.. anyway.. if you can, give your motor a compression test just for sh*ts and giggles. But the turbo seal.. its pretty easy to tell just with the downpipe removed and the heatshield off with a good visual inspection.
Sorry for my rambling and hoped i helped a little bit telling you my scenario.
Good luck!
