The other day I went out to drive my 95. The car hadn't been driven in a couple of days. On start up I got some smoke out the exhaust. It cleared up within the first minute of running but is the sign of something failing?
Ehh, they'll do that. After sitting awhile, you can get condensation in the exhaust. Or it could be a leaky oil seal somewhere in the turbo. If it just does it every once in awhile, don't worry too much about it.
Smoke is white. It was the first time it was noticed. I'll have to get back with you on WOT as I don't drive the car very hard. It has 140k miles and I know things will fail. Turbo was replaced about 50k miles ago. The amount of smoke wasn't bad like when a turbo goes, but bad enough to notice on start up.
328iC - water/coolant is usually what causes white smoke.
Does your car feel sluggish? Do you notice your turbo spooling up fine? Are you losing coolant? You said the turbo was replaced - you could check the coolant lines to the turbo to make sure nothing came loose.
Do you smell anything sweet (a sign of coolant burning - and a lean towards the head gasket failing and starting to cause the white smoke). If it is the head gasket, sometimes it is a matter of re-torque of the head bolts to tighten down the gasket again.
