Valve lifter guide springs may be installed on the valve lifters only once. If a valve lifter guide spring is removed from a valve lifter, the valve lifter guide spring must be replaced with a new valve lifter guide spring. If the valve lifter guide spring is not removed from the valve lifter, the valve lifter can be replaced in the original location without replacing the valve lifter guide spring.
Inspect the valve lifter bores in the valve guide (1) for wear.
Ensure that the lubrication passages in the valve lifter guide are not obstructed.
