Hi all, I have a bit of white smoke on my Fiero. It doesn't smoke when idling, but after idling a bit, if i rev it i get a good puff of white smoke. Smaller amount if i rev after not allowing it to build up under idle.

I have done a compression check, and since it only ranges over 4 psi from low to high cylinder, i don't believe it is cracked head or head gasket. My current guess is intake manifold gasket. On the fiero based duke engine, it has a hot water passage next to the #4 runner on the intake manifold. My guess is that the intake gasket is allowing a bit of coolant into the intake.

What do you think...possible?

Thanks, -Scot
