hi all, hoping for some help on this one because im going to start crying soon!on cold start there is not even a hint of smoke.when you drive the car (gently of course because it is a new engine!) when the engine has warmed up it smokes under accelaration, but tries to clear on over-run.then if you park up it will continue to smoke on idle.if you leave the car for a couple of minutes and restart it then there is again no smoke!i have looked at the spark plugs and they aren't really oily at all!i have already sent the turbo back to be inspected and apparently all is ok and within spec.

any help appreciated

thanks matt

 

Valve stem seals???

Very common

 

were replaced as part of the engine rebuild

 

Had similar problem with mine, changed the stem seals and touch wood been ok since

 

how many miles it done, as can use a bit of oil till all bedded in, but smoke on tickover does point to turbo though, hope you get it sorted as things like this are frustrating especially after spending so much money to get it right, best of luck, I would have thought guide seals would smoke on cold start and overrun not under acceleration but maybe wrong.

 

iv only done about 5 miles in the car.don't really want to do any more than that smoking as it does!i want to try another turbo on the car so i can definitely eliminate that.anyone got one i can borrow????pretty please with a cherry on top!
