Default White smoke out of exhaust @ WOT

When I was taking off in WOT, my buddies said that they noticed greyish white smoke coming out.

I've searched and found nothing.

Is this serious? I figure it would be water getting into the cyl., but isn't that bad?

pretty normal as far as i know.

as long as it isn't pouring out.

this is probably due to the fact that when you take off and shift gears when going WOT the car runs rich (which is normal).

that's my semi-educated guess, but someone more knowledgeable can correct me.

As beanolo says, nothing to worry about as long as it's an isolated incident -- probably just "blowing out" some deposits and/or running rich.

If it continues to happen, take note of the circumstances and, uh... call us in the morning.

It's a combination of running rich at WOT, and soot build up in the exhaust system getting blown out. Both are normal.

The baffle in the resonator of my exhaust is messed up, and I noticed that my gas mileage has gone down. Till I could get the exhaust fixed, does it affect my gas mileage?

Yes. Engine performance both power output and economy will drop with restricted exhaust.
