Okay here's the deal. I start the car when it's cold and get the normal amount smoke, but while it's warming up all of a sudden massive amounts of smoke start pooring out of the exhaust. However, it goes away after a while, and then the car runs fine.

1.) Bad turbo?
2.) Coolant Seals?

What could this be?

 

What color smoke and what mods are you rockin'? White smoke can be condensation (if short lived) or coolant (but coolant is sweet smelling), black is typically fuel, and blue is oil.

 

My car too will run fine, normal or no amount of smoke, then randomly, will billow huge clouds of blue smoke. I've taken it to a shop and they can't figure it out. Had me hold the engine at 4000 for about a minute, then let off, no smoke so they felt the seals were good. Compression is good. The car has new turbos, so it's not turbo seals. It's difficult to figure out because the blue smoke happens very randomly. Sometimes upon startup, sometimes not. Sometimes when your running around town under 3000 rpfm and come to a traffic light stop. Sometimes it won't smoke for a day or so, then will start up again.

If you end up finding anything out, please let me know.

Thanks
