2007 Chevrolet Corvette Valve Stem Oil Seal Parts Questions & Experts Answers

• Q: What tools are required to service and repair the valve guide seal, replace the valve stem oil seal, and valve spring on 2007 Chevrolet Corvette?

  A: Repairing the Valve Stem Oil Seal alongside valve guide seal and spring work requires two specific tools: j 22794 Spark Plug port adapter (J 22794) and j 38606 valve spring compressor head-on (J 38606). Connect the j 22794 socket tool to the Spark Plug opening and join an air hose to it after unthreading both components. Use a plastic face hammer to tap the valve stem end carefully to remove sticking valve stem keys. Apply the j 38606 valve spring compressor to push down the valve spring. Next take off the valve stem keys. To free the valve spring tension use j 38606 first then ease the spring compressor pressure followed by valve components removal. Before putting the new valve guide seal and shim in place, clean the valve spring seat of the Cylinder Head and adjust the parts to block oil from leaking out and worsening vehicle emissions. Apply engine oil to both the valve stem and valve guide seal before placing the oil seal onto the valve stem until it rests on the valve guide surface. After installing the valve spring onto the j 38606 tool you need to compress it before placing it on the Cylinder Head. Place the valve spring cap and valve stem keys on the head while using grease to hold the keys in position. Set the j 38606 keys back in place at the valve stem groove after you have put the valve spring pressure back. Apply a light tap from a plastic hammer tip onto the valve stem's end if needed to properly place the keys. Take out the air supply from j 22794 and remove it from the Spark Plug hole. Measure the valve spring installed height. Install an extra 0.5 mm (0.02 in) thick valve spring shim if the measurement exceeds 46.25 mm (1.82 in). Place the last components in their correct locations: plugin the Spark Plug followed by fitting the valve rocker arms.
