How to Change Head Gaskets on a 3000GT

A blown head gasket in a Mitsubishi 3000GT can impact the engine's performance, as well as the vehicle's fuel efficiency. When there is a hole in the gasket or it is overheated, the coolant can mix with the engine oil and damage the block. When a head gasket leak develops, it makes a tapping noise.

Replacing the gasket takes between 4 to 6 hours of complete.

Drain the coolant and oil from the engine. Remove the intake manifold. Unscrew the exhaust manifold.

Remove the camshaft sprocket from the camshaft using the MD998754 torque wrench. Remove the timing belt rear cover. Remove the timing belt. Unscrew the power-steering pump-bracket connection and generator-brace connection.

Disconnect the vacuum-pipe assembly. Remove the rocker-arm cover. Using the MD998051 torque wrench, unscrew the cylinder-head bolts. Take out the cylinder head. Remove the old cylinder head from the engine block.

Lay the cylinder head gasket on the cylinder block with the identification mark at the front top. Follow the operations above to reassemble the removed parts.
