This means that water is passing through your exhaust system which usually means that either a head gasket went bad or crack or warped head.

AnswerDid you repair the car first? Because if not your engine is probably hurtin' (blown head gasket or warped head). The most common leak in a blown head gasket is the anti-freeze.

White smoke is anti-freeze burning (or boiling) and you probably noticed you're losing anti-freeze from the reservoir. Also check your oil for overfilling and a greenish additive that YOU didn't put in. You can try STOP-LEAK but be aware this DOES NOT provide a permanent fix.

If you have the money have a professional look at your car and fix the head gasket and/ or the possibly warped head.

AnswerI had this problem with a 1975 Honda civic......turns out a cylinder burned a hole and the water mixed with the oil making white smoke come out of the exhaust.

Reason: Improper maintenance. I never got oil changes or added oil. or checked the water or checked for leaks.....Etc...

Repair: Change the cylinder. Very expensive $?

New Engine $500.00 rebuilt (already more than the car was worth) plus Labor$?
