2005 Chevrolet Avalanche 1500 Valve Stem Oil Seal Parts and Q&A

• Q: What tools are required to service and repair the valve stem oil seal and valve spring on 2005 Chevrolet Avalanche 1500?

  A: Serviceability of valve guide seal and valve spring needs Spark Plug port adapter (J 22794) and valve spring compressor (J 38606). First detach the Rocker Arm and unscrew the Spark Plug wire at its port. Twist each wire boot half way and pull purely from the boot to disconnect the wire. At normal engine temperature loosen spark plugs 1 or 2 turns before air blowing their dirt away and taking them out. Insert the Spark Plug port adapter part j 22794 into the Spark Plug hole then link an air tube and blow air to retain valve function. Use the valve spring compressor j 38606 to compress the valve spring ahead of removing valve stem keys followed by slowly releasing the spring tension and taking out the compressor. First take off the valve spring cap followed by the valve spring and valve guide seal plus its accompanying shim. Clean inside the Cylinder Head valve seat area while placing the valve guide seal and shim over clean engine oil. Press the valve spring into place with the valve spring compressor (J 38606) while placing the valve keys in position and holding them with grease. Check if the key fits into the valve stem groove and ease valve spring pressure while pulling out the compressor tool. Use the plastic hammer gently to set the keys in place if needed. Complete the job by starting the Spark Plug manually and tightening it to 11 ft. Lbs. Attach ignition coil wires then inspect the connections before fitting the Rocker Arm again.
