Valve Train Analysis - Dynamic

Start the engine and, while idling, check for proper operation of all parts. Check the following:

Roller Follower
- Check for plugged off cylinder head.
- Check for proper overhead valve train lubrication.

If insufficient oiling is suspected, accelerate the engine to 1200 rpm + 100 rpm with the transmission in NEUTRAL and the engine at normal operating temperature. Oil should spurt from the roller followers oil holes such that the valve tips and roller followers are well oiled and/or, with the valve covers off, oil splash may overshoot the roller followers. If oiling is insufficient for this to occur, check the oil passages for blockage.
