Common questions
What are signs of a bad head gasket?
White smoke, rising coolant loss with no leak, bubbles in the coolant, and milky oil are common signs.
Is it worth repairing an older car?
It is often a large repair, so compare it with the car's value. Some owners choose a used or rebuilt engine instead.
Do additives fix it?
Rarely, and only as a short-term patch. Sealers can clog small coolant passages. A proper repair means taking the engine apart and checking the head for warping.
