Head Gasket Repair Cost & Warning Signs
A blown head gasket sounds scary — and can be expensive. A Cranbourne West specialist explains the warning signs, what repair involves, and how to catch it before it gets worse.
Warning signs of a head gasket
Classic signs are overheating, white smoke from the exhaust, coolant disappearing with no obvious leak, a creamy “mayonnaise” residue under the oil cap, or bubbles in the coolant. Any of these means stop driving and get it checked.
Driving on a blown gasket usually makes the damage (and the bill) worse.
Why it costs what it does
Head gasket repair is labour-intensive — the top of the engine comes apart, the head is checked for warping (and machined or replaced if needed), and it all goes back together with new gaskets and fluids. The price depends heavily on the engine and what damage is found.
We diagnose properly first — sometimes the symptoms point to a cheaper fix than a gasket — and give a fixed written quote.
Catching it early
Most head gasket failures follow overheating. The best protection is a healthy cooling system and acting the moment the temperature gauge climbs — a $200 cooling repair beats a head gasket every time.
