7. Install other valves in the same way. Recheck the height of the springs (photo) and adjust with washers. It is not allowed to install extra support washers if the initial height of the spring in working condition is correct.
10.7 Rechecking the height of the springs
8. Install camshaft, rocker rollers and tappets (on V6 engines).
