Inspection
NOTE: Do not attempt to straighten push rods.
Check the ends of the push rods for nicks, grooves, roughness or excessive wear. Replace damaged push rods.
The push rods can be visually checked for straightness while they are installed in the engine by rotating them with the valve closed. They also can be checked with a dial indicator.
If the push rod is bent beyond specifications, it should be replaced.
