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
