My exhaust spews white smoke, not all that much, but I'm told the only thing coming out should be water. This morning for about 10 secondes as I was backing up into a parking spot, it was really bad because I could see it on my rear mirror, normally I can't see. It's not the coolant because I check that regularly and the level is steady. What else could it be?

 

It's probably condensation. My 3.2 does this sometimes too in the mornings when it's cold outside. As long as it's intermittent and not constant then just live with it. No big deal.

 

When it's cold out, you'll see some steam coming out of the tail pipe. Are you sure it's white smoke and not steam?

 

I'm not quite sure I know the difference between white smoke and steam. But I put the car in P and got out to smell it and it smelled fresh not anything nauseating at all. I guess that could be steam.

Another thing, I have a failed PCS (something solenoid, which triggered code P1459 evap incorrect purge flow) which I did not replace (because as long as I don't fail emissions I'm not paying), can that contribute to white smoke?
