White smoke coming from the tailpipe.
BUBBLING IN THE RADIATOR AND COOLANT RESERVOIR.
unexplained coolant loss with no leaks.
Milky white coloration in the oil.
Engine overheating.
Can a blown head gasket cause multiple misfires? Cylinder misfire is another sign of head gasket failure, especially if the breach is between two cylinders on the same head. Cylinder compression and leakdown tests can localize the leak for scrutiny on disassembly.
What do spark plugs look like with blown head gasket? Inspect each spark plug for failure signs.
