4.4 - INSPECTING THE ENGINE ELEMENTS

CYLINDER HEAD

CHECKING FOR TIGHT VALVE SEATING

- Test both the inlet and the exhaust valves.

- The test should be carried out by filling the manifold with
petrol and checking that petrol does not ooze excessively
past the valves.

Tight valve seating => Refit cylinder head.

Leaking valve seating => Dismantle and grind the valves.

STEPS TO FOLLOW TO DISMANTLE THE VALVES

- Position the cylinder head on a supporting surface.

- Number the valves and the shims to ensure they are
refitted in the correct positions.

- Extract the shims from the valves.

- Use a suitable tool to compress the valve springs.
