    Q:
    How to service and repair the Rocker Shaft Spring Kit and replace the Valve Stem Oil Seal on Chevrolet Tahoe? Posted by Customer
    A:
    To repair valve stem components you should first remove the valve rocker arms and spark plugs in the Cylinder Head. You must put the Spark Plug port adapter (J22794) into the Spark Plug hole and seal the valves with compressed air. Start with the valve spring compressor tool j5892-d and add a valve Rocker Arm m8 bolt plus washer to squeeze the valve spring. After that you can switch to the valve spring compressor j38606. Disengage the valve stem keys afterward depress the valve spring pressure then take off both valve spring compressors (J38606) valve spring cap valve spring and valve stem oil seal. In addition you should take out these extra valve spring shims when needed. Start the engine repair by placing the valve spring shim kit if present before adding the valve stem oil seal to the valve guide. Ensure that the seal aligns correctly to block oil leaks. Add engine oil to the valve guide and stem oil seal before attaching the seal to the stem and letting it reach the valve guide. The valve stem oil seal installer tool j42073 must push or gently tap onto the valve spring shim or spring seat to install the valve stem oil seal. After putting in the valve spring components put the valve spring compressor tool over the valve spring to pressurize it again or use valve spring compressor (J38606). Apply grease to hold valve keys steady and low-pressure the valve spring to secure the valve keys in position. Take out both the valve spring compressor j5892-d and Spark Plug port adapter j22794 before inserting spark plugs and returning the valve rocker arms to their proper position.
