Engine Running, Roller Follower

- Check for plugged oil hole in roller followers or 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 follower 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.
