Is it oil or it it fuel. When they overfuel bad the exhaust joints leak what looks like oil but its the unburned fuel.
Worth cheaking

yeah seems so but as robrs2 states could be unburnt fuel onli thing that sways that from fuel is its usually when engine upto running temp and get a few drips and surely fuel would ignite as it drips on exhaust and is doesnt seem to ignite ????

robrs2

No you will still get fuel liquid out the exhaust joints. Most times it can be seen on the joint between the 2 halfs of a 2wd manifold.

cheers i will have to take turbo off thinking of bringing car off road for a few weeks anyway as i dont like the smoke i am getting i know the bottom end compression is fine. wworried about the head now and turbo.... as when i had bottom end re built i just replaced stem seal and re seated the valve but no harm in stripping it off or at least having the head and cylinder compression done....

cossies eh.... joys of motoring

i would check inside your boost hoses and see if there is any trace of oil, while the intake pipe where it fits compressor housing is off check for any excess play in shaft that should tell you if its your turbo
