I have a PT 88 on a 402 anyway it's all new. I have really bad smoke problem with turbo. It is putting oil in the DP. I took the DP loose and foun the inside of DP is coated really bad in oil. Smokes like a train. This a brand new unit from Forced Induction. I have a -4 feed line running to the turbo and the drain is a -10 the drain is working fine. I was told by a friend that he new someone with same problem and they were told to restrict the oil feed line. Like with NOS jets until the smoke went away. Is this correct? I have never read anything about this. Any help would be much appreciated.

I had the same problem till I put a scavenge pump on it. No smoke now. Chances are its draining correctly.

How is your turbo mounted, high or low? And like Beasst, some guys run a scavenge to eliminate the problem.

it is mounted in front of the crank pulley alot like the OFI setup. The drain is working fine. I took drain loose and hardly any oil came out of it. If it was a drain back problem than it would go away when jacking up the front of car to check it.draining back.

I am running a gt42 with a 0.060 restrictor, it was the only thing that rid of my smoke (it is mounted very low with scavenge pump). I had the same problem, do a search with my name, alot of people chimed in with suggestions.

edit - did you say the oil does NOT drain from the turbo when you remove the oil downpipe?

??? Well what is that then? Oil should have came out if it wasnt being hung up anywhere.

edit: Was the car running when you tried this?

no the car wasn't running. If there was drain probs it would have had oil backed up in the drain.
