Head Gasket Trouble: The Early Signs Worth Catching

“Blown head gasket” is the phrase nobody wants — but it announces itself early, if you look.

Small symptoms before the big bill

White sweet-smelling exhaust on startup, coolant that disappears with no visible leak, bubbles in the reservoir with the engine running, milky residue under the oil cap — each is the gasket starting to let go between passages. A chemical block test confirms combustion gases in the coolant in minutes. Early, options exist; after repeated overheats, they mostly do not.

Quick tips

  • Never keep driving an overheating engine “just to get home” — that is how gaskets die
  • A little morning condensation from the tailpipe is normal; billowing sweet smoke is not
  • Track coolant level weekly if you suspect anything — the trend is the evidence
