Condensation/Water leftover in exhaust burning off as it warms up.

Worst case is a coolant leak into one of the chambers. When it is parked the coolant is still under pressure and is forced into the chamber. My old RX-3 developed a leak and while it was off coolant leaked into the chamber and when I started it it smoked like one of those insect fogger trucks for a few minutes until the coolant cleared out.

Hey Gents having problems with my cel-took it to private dealer and computer says bank 1 sensor 2 damaged-anyone knows which lambda sensor that is?

it could be a condensation.. or a leaky valve seals.. White smoke is usually either coolant in the engine, or oil in the exhaust from a turbine seals..

Leaky valve seals?
Could just be a burned valve guide or bad cam timing.
He should check to see if his timing belt has slipped.

Might as well ignore this thread, he hasn't checked back since he started it.
