A head gasket repair requires significant labor to remove and reinstall the cylinder head. While the head is off, replacing a few related parts can help avoid doing the job twice.
Head Bolts
Many modern engines use torque-to-yield head bolts, which stretch during installation and are specified by the manufacturer for one-time use. Check the service information for your engine; if the bolts are torque-to-yield, replace them with a new head bolt set.
The Complete Head Gasket Set
A head gasket set typically includes more than the head gasket alone. Depending on the part number, it may include intake and exhaust manifold gaskets, a valve cover gasket, valve stem seals, and related seals. Reusing old gaskets that have already been compressed and heat-cycled can lead to leaks after the repair.
Inspect the Head and Block Surfaces
Overheating is a common cause of head gasket failure, and it can also warp the cylinder head. Check the head and block deck surfaces for flatness and have the head serviced by a machine shop if needed. Clean surfaces thoroughly according to the gasket manufacturer’s instructions.
Address the Root Cause
If the original failure was caused by overheating, inspect the cooling system, including the water pump, thermostat, and radiator, before returning the vehicle to service.
