Dynamic (Engine Running)

VALVES AND CYLINDER HEAD

NOTE: Static checks (engine OFF) should be made on the engine prior to the dynamic procedure.

1. Remove the valve cover.
2. Start the engine and, while idling, check for proper operation of all parts. Carefully observe and inspect the following:
a. Check for proper valve train lubrication.
b. Check for plugged oil feed in the rocker arm or the cylinder head.
c. Check for proper operation of positive rotator.
d. Check for plugged oil drain back holes in rocker arms (6564) or cylinder head (6049).
e. Check for plugged oil drain back holes.





f. Check for plugged oil metering orifice in cylinder head oil reservoir.

INSUFFICIENT OILING
If a condition of insufficient oiling is suspected accelerate the engine to 1200 rpm, ±100 rpm with the transaxle in Neutral (N) and the engine at normal operating temperature. Oil should spurt from the rocker arms so that the valve tips, and rocker arms are well oiled. If insufficient oiling is still suspected, check engine oil level, check oil passages for blockage, and check for proper engine oil pressure.
