hey guys i have 5 low comp 5e fitted in mt gt and it smokes only when i have a turbo install on it i have installed 3 turbo to date all of which have caused the car to smoke with the last and latest turbo being brand spanking new .

the smoking happens similar to when u have bad valve seals that is if you going down hill in lets say third gear just coasting no smoke but to the bottom when u get on the gas then it starts to smoke again.

now here is what puzzles me. i put on the stock 5e exhaust Mani and hooked it up to the exhaust with an adapter so no turbo installed and i blocked off all oil line for turbo and water lines drove for 2 Weeks like this and no smoke

can any one help me cause im lost

Could the extra pressure in the cylinders be causing excessive blowby? What's the condition of your oil? What about the pcv valve?

that's a bit strange...kind of unlikely for 3 turbos to be all bad
does it smoke on first start up at all?---valve stem seals?
how's you compression?

what about your turbo set up?...any oil restrictions or steep angles?
do you have a picture of the turbo set up?

yeah...in relation to the general set up
how the manifold and turbo sit relative to each other----are they level
how the oil feed and oil return lines fit

i know sometimes people try all kind of interesting set ups and have the turbo off at less than ideal angles

that's why i was asking for a picture of your set up
