i've got a gte 16v which at idel is fine but i noticed onces stoped at a traffic that there was a lot of white smoke coming out it must have been as i booted it in 1st and 2nd gears 30 seconds before stoping.
after that i have kept an eye on the rear and notice it only smokes know and then usually when its been booted, anyone have any ideas as i would be greatful.
The white smoke that you mention could actually be steam. It may be an idea to check your cylinder head gasket. Check the condition of your oil, has it went white around the filler cap? Also remove radiator expansion bottle cap, with the engine running look for a stream of air bubbles. The only other thing I can think of is a valve stem oil seal on the way out. I had this with a previous car and cured it by adding stop smoke to the oil.
