i have just had a reconditioned turbo (t3) put on my st escos because it was smoking before... but it is still smoking, only when i leave it run in gear, no throttle, and mainly when i go down hills. it doesnt smoke when i drive car normaly, or accelerate, just when i leave it run in gear when i shut off, could it be there is oil in my intercooler from before? or could it be a blocked breather because it tends to happen when im doing down hill first.

there is a breather pipe going into my k+n airfilter... is there another pipe going into the inlet manifold...(cant think off top of my head).

any help be great guys

cheers liam
