I have an 03, NA with 27k miles. There is white smoke under deceleration, nothing under throttle. Does not smell like coolant and the level is fine, matter of fact it doesn't really have a smell at all. Oil level appears ok as well. Car runs fine, no CEL, would never had known if a few people didn't tell me about it while on track.

I'm stumped at this point.

 

Got test pipes?

 

Yes actually, but I don't recall this happening before.

 

i am experiencing this same thing at the moment, yet i do see some while leaving from a stop sometimes. I don't know what it is yet, many people seem to think it might be a head gasket, but i have yet to perform a compression test.
