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

  A:

  Two tools are needed to do this work: j22794 Spark Plug port adapter and j38606 valve spring compressor. Untwist the Spark Plug wire boots 1/2 turn before pulling off the entire boot from the Spark Plug end. Take the spark plugs out from the Cylinder Head when the engine stands at normal indoor temperature but rotate them 1 or 2 turns initially for air or cleaning before pulling them all the way. Use the Spark Plug port adapter j22794 to position the Spark Plug hole while connecting an air hose and passing compressed air to fix the valves in place. The valve spring compressor model j38606 helps you compress the valve spring before you take out the valve stem keys and slowly let go of the valve spring pressure. This step completes the spring compression process. First take off the valve spring cap then the valve spring along with Valve Stem Oil Seal and shim. Apply engine oil to the valve guide and Valve Stem Oil Seal then position the Valve Stem Oil Seal and required shim on top. Fit the valve spring into position and valve spring cap on top. Use the valve spring compressor (J38606) to load the valve spring before installing the valve keys through their grooves on the valve stem. After letting off valve spring tension gently remove the compressor. Then hit the plastic-headed hammer on the valve stem tip to seat the keys when needed. Begin by removing the port adapter j22794 and manually start the Spark Plug using hand torque. Tighten it to 15 nm (11 ft. Lbs.) before connecting Spark Plug Wires to their corresponding locations at the Ignition Coil and Spark Plug. Double-check correctness before installing the Rocker Arm.
