is sort of like a high altitute contrail one sees behind a jet plane.

Exhaust from the cold engine contains a good bit of water vapour (see OPINIONS re: spelling).

That warm vapour-laden gas hits the cold surrounding air and immediately cools, causing the vapour to condense into droplets. Like fog.

So when the engine reaches operating temperature the water vapour is little or none, and the exhaust is (or should be) clear.

White smoke after engine is at operating temp still means water vapour, and that's a signal for a problem like a bad head gasket.

Good Luck,

Bob
