Turbo stem seals???
I think mine are knackered.
It aint smoking on idle, but i got oil coming out the d/valve and when i put the foot down and the boost starts to kick in, i get a puff of smoke out the exhaust (tho only one)
I was racing my m8 the other day and he said that every time i went over a bump, a puff of smoke came out the exhaust.
I know that there aint too much oil in it, can there be any other explanation??
It could be from the turbo
Triple-check all ventilation pipes, and intake & exhaust path for sneaky leaks
