Looking for some help here. Just finished up putting together a 2005 Twin Turbo v6. After getting it all together and broke in, it started smoking from the exhaust after start up for a few minutes. After that it is fine.

It is white smoke. It doesnt look like a head gasket is blown as my oil is not contaminated. I think it may be the Valve Stem Seals are done. I think that is my next step but if there are any other ideas out there before I go yanking those out I would appreciate some feedback.

This build has been a long time coming and its getting close to race time and I want to see what she will do but i would prefer not destroying her in the process. Thanks all!:smoke::needahand:

White smoke = water
Blue smoke = oil
black smoke = gas

If it were valve seals, I would suspect blue smoke.

do a compression test of each cylinder. H2O is a natural byproduct of burning gasoline, could it be that its just natural condensation in the exhaust because its cold? do you have catalytic converters anymore?
