Where’s the job?

Scope of Works

• Inspect engine, run diagnostics and confirm coolant/oil contamination

• remove and strip the cylinder head if required to access the gasket

• replace head gasket and associated seals, hoses and gaskets

• check head and block for warpage/cracks and arrange head skimming or machining if needed

• fit new head bolts/studs and torque to manufacturer specification

• pressure test cooling system, flush coolant and replace contaminated oil as required; use PPE when handling fluids

Typical Cost

Time on Site

Typical workshop time is 1–3 days, equivalent to about 6–16 hours of labour spread over dismantling, machining (if needed) and reassembly; times extend if the head needs specialist machining, parts are on back order or additional engine damage is found

Questions to Ask Your Tradie

• have you repaired head gaskets on this make and engine before

• will you include head inspection, pressure test and any required machining in the quote

• do you fit new head bolts/studs and provide a parts and labour warranty

• what will you do if you find a cracked block or badly warped head and how will extras be authorised

• are coolant and oil flushes included and do you test for oil contamination (emulsified oil)

• roughly how long will the job take and when can you start

How to Avoid Surprises

• confirm parts availability for your engine before work starts

• arrange parking or vehicle drop-off and tell the garage about immobilisers or alarms

• advise the tradie of previous overheating or timing belt history before quoting

• ask for written estimates for machining or further repairs and agree an authorisation limit

• remove personal items from the car and provide keys and contact details for updates
