14.1.2 Intake and Exhaust Valves

There are four valves per cylinder; two intake valves and two exhaust valves.

Valves are made of heat-treated alloys, w ith precision-ground heads and stems. Stem ends are

hardened to minimize wear in contact with the valve rocker buttons.

All valves are retained by valve spring caps and two-piece tapered valve locks.

Valve stem oil seals are installed on both intake and exhaust valves to provide controlled valve

stem lubrication while limiting oil consumption.
