1994 Honda Civic White Smoke from Tailpipe

Suggested Repair

Check whether the coolant level is dropping. If coolant is disappearing and the white smoke clears quickly without an oil-burning smell, have the head gasket inspected and replaced if needed. Cost depends on the shop and on related problems such as valve seals, seats, or a cracked head; one estimate given was $300 to $500 in the Los Angeles area, so get a local quote in South Carolina from a reputable mechanic.

Conversation Summary

The owner of a 1994 Honda Civic with about 135,530 miles reported white smoke from the tailpipe that increased during acceleration, dispersed quickly, had no burning smell, and occurred without overheating. The expert said the smoke could be oil or water vapor and asked whether radiator coolant was disappearing. If coolant is being lost, the head gasket should be replaced; price depends on the mechanic and on whether valve seals, seats, or a cracked head are also involved, with a rough Los Angeles estimate of $300 to $500. The owner is in South Carolina and stopped driving the car.
