Default White smoke out of exhaust?

Well in light of this cali summer weather, i washed the S and the went out for a drive on the twisties with two of my friends with bikes. Well about half way through our drive, white smoke starts bellowing out of my exhaust. I am almost positive this was just water from the wash goin in my PRM, but............. does anything else create white smoke? Water going in the intake at that high of temperature i would assume would just evaporate and not do any damage to the piston right? thanks for the insight

If you were doing sustained high-g turns (left turns I think) and your oil level is high or a little overfull, you can get burning oil (white smoke). Happened to me once but now I have oil changes down to a science.

Its normal, especially on my 01 b/c the ECU dumps fuel into the motor during VTEC.. Im not sure about the 03 ECU though. And if it was just a minute amount of water, it would actually clean your engine.

This would create black smoke.

White smoke after a high speed right handed sweeper is from oil being pulled through the PCV valve.

A baffled catch tank on the PCV line that works as a oil seperator keeps the smoke away.

On a previous car, I had a cracked head gasket that was causing coolant to get into the pistons and resulted in white smoke with a faint smell of coolant.

Failed head gaskets on a Stock S2k are very rare.

Those who have head gasket failures are running lots of boost, different head studs, and thicker gaskets.
