FAQ for Other Repair Info

Q: How to remove the valve lifter?
A:
You will need to remove the lower intake manifold, the valve rocker arms, and pushrods, loosen the Valve Lifter guide bolts then remove the valve lifter guides, remove the valve lifters from the valve lifter guides and clean all gasket surfaces with a degreaser.
Q: What's the proper way to remove the valve stem oil seal and valve spring?
A:
The proper way is to remove the spark plug, and the rocker arm, install the J 22794 into the spark plug port, using caution so as not to damage the Valve Spring or valve spring dampener, compress the valve spring using the J 5892-D and the EN-47823, then remove the valve spring cap keys, the valve cap, the valve spring, and the valve stem oil seal.
Q: What tools should be used when tightening the valve rocker cover bolts?
A:
You should use an alternating criss-cross pattern when tightening the valve rocker cover bolts. Failure to do so may result in oil leakage from the Valve Cover due to improper seating of the gasket.
