When I start my car up, within 30 seconds white exhaust smoke starts bellowing
out the exhaust and continues for a while. After car warms up, it stops. Was told
by one mechanic that it was either a bad head or needs a head gasket replaced.
I personally don't think it's either of the above problems because the car is not overheating at all. But now there seems to be anti-freeze on my front windshield
and back window on the inside. Is that a bad heater core?
I'm not adding coolant on a regular, so for now I can eliminate the heads,
but I will look into the sticking injector or the fuel pressure regulator. Also
the car starts up fine hot or cold (besides the white smoke ). And I know
I will get that heater core replaced.
