Head gasket
testing & repair

White exhaust smoke, coolant disappearing or milky oil can mean a blown head gasket — or something much simpler. We test at your place first, so you know exactly what you’re dealing with before any big decisions.

About this service

Test first, then decide

The head gasket seals the gap between the engine block and the cylinder head, keeping combustion gases, coolant and oil in their own channels. It usually fails after the engine overheats.

Because the repair is major, an accurate diagnosis matters. We do a combustion-gas (block) test and a cooling-system pressure test on site. If the gasket has failed, we quote the repair — including machining the head — and can transport the car to our Truganina workshop.

FAQ

Head Gasket questions

What are the signs of a blown head gasket?

White exhaust smoke, unexplained coolant loss, milky oil and repeated overheating are the classic signs. A block test confirms it.

Can a head gasket be replaced at home?

Testing, yes — we do that on site. The replacement itself needs the cylinder head machined, so it’s done at our Truganina workshop.

Is it worth fixing a blown head gasket?

It depends on the car’s value and condition. We’ll give you an honest diagnosis and quote so you can decide.
