My TII, after boosting and decelerating, smokes quite heavily.
At first I thought it might be because I was running so rich, but now I have leaned it out and it still smokes the same.

It's a bluish/white smoke and it smells like oil.

I was thinking it could be the seals on my turbo, but when my last motor blew up, the turbo didn't smoke at all?

This just started with my current engine and Haltech install.

Anybody have any ideas what would make it smoke so bad on deceleration?

Bad oil control seals...

more likely your turbo is on the way out. If it were oil control rings it would smoke heavily when cold, and very little when warm.

Pop one of your I/C hoses off and take a look in there. That should tell you if the turbos blowing oil or not.

It's not the turbo.
I think it's the O rings.

make sure the crankcase vent is free flowing. had some oil in mine and caused turbo to smoke . cleared line and smoke gone. may need to remove turbo to be sure. pull the plugs and if they are clean oil is coming from exhaust side of turbo. then check vent lines and lastly pull turbo and look for oil residue.

Crank Case Vent?
Never heard of it? Where is it at?
