I am experiencing white smoke/vapor emanating from the exhaust on my 1996 VW Jetta GL 2.0. It seems light at first, then gets worse as the car heats up to temperature.

I had problems starting the car last week (cold and rainy) and had to crank the engine 10-15 times over 2 days to finally start it.

I had the spark plugs, cap and rotor replaced and the car starts fine but emits white smoke/vapor from the exhaust. It does not smell of gas or oil.

I took the car to a dealer and they ran a diagnostic (compression and leak check) and the cylinders tested normal. The dealer service dept. told me the smoke/vapor could be due the catalytic converter being soaked with gas from cranking the motor and would eventually go away. They also told me the amount of smoke/vapor was not abnormal.

There are no MIL codes in the computer and I have no further way to troubleshoot except to drive it and see if it gets better. I am not sure if I risk damaging the engine by driving it.

Any suggestions would be appreciated.

Try changing the motor oil, excessive gas while cranking can wash the cylinder wall and then gas gets into the crankcase...
