Fitting tips

1. Clean the groove in the cover and the cylinder head face.
2. Seat the gasket properly in its groove; sealant goes only where the manual calls for it (often the camshaft half-moons).
3. Tighten the screws in a criss-cross pattern to the manufacturer's torque, without crushing the gasket.
4. While it's apart, adjust the valve clearance with valve shims if needed and replace the spark plug.

Frequently asked questions

Should it be replaced at every valve check?
Not necessarily if it is still supple and intact, but a hardened gasket always ends up leaking.
