Inspect Push Rod
A.
Place the rocker arm push rod on V blocks that are as
far apart as possible, and set a dial gauge [A] on the
rod at a point halfway between the blocks. Turn the
rod to measure the runout. The difference between
highest and the lowest dial readings is the amount of
runout.
B. If the runout exceeds the service limit, replace the
rod.

Inspect Rocker Arm

Clean and inspect the rocker arm where it touches
the push rod and valve stem.
B. If the contact points [A] are worn or damaged,
replace the rocker arm.
Measure Cylinder Head Warp
A.
Lay a straightedge [A] across the lower surface of the
head at several different points, and measure warp by
inserting a thickness gauge [B] between the straight-
edge and the head.
B. If warp exceeds the service limit, repair the mating
surface. Replace the cylinder head if the mating sur-
face is badly damaged.
