  Q: How to replace the Rocker Shaft Spring Kit and valve stem oil seal on GMC Sierra 1500 Classic?

  A:

  To replace valve-stem oil seal and bring back the vehicle valve spring replace the required value Rocker Arms and Spark Plugs first. Drive the Spark Plug port adapter (J 22794) into the Spark Plug hole; connect a shop air supply hose and apply compressed air to let the valves stay in position. Mount a flat washer on the bolt you uninstalled, then bolt it and Rocker Arm to cylinder head on the valve spring removed. Be careful as compressed valve springs are under high tension with valve spring compressor, which may injure the person due to misuse. Exert steady pressure while compressing the valve spring by hooking its slotted end underneath the washer on the Rocker Arm bolt using the valve spring compressor (J 5892-D) until the valve keys can be reached. If required, valve spring compressor (J 38606) should be used to provide absolute engagement on the valve spring. Disassemble the valve keys and carefully release the valve spring tension, and remove the j 5892-d or j 38606 subsequently and removed valve spring cap and valve spring. Choose the correct Valve Stem Oil Seal, lubricate it along with the valve guide using clean oil from the engine and install it on the valve guide using Valve Stem Oil Seal installer (J 42073). It is necessary that there should be a 1 - 2 mm gap between the base edge of the Valve Stem Oil Seal and the valve guide. Reinstall the valve spring and valve spring cap and then compress the valve spring for the second time using the j 5892-d or j 38606 in those cases. Place the valve stem o-ring seal and valve stem keys with the help of grease to hold the keys on place. Gradually let the pressure off on the valve spring while making sure that the keys do not come off and remove the j 5892-d or j 38606. Finally, verify the valve stem keys are in the upper groove of the valve stem and tap if necessary, then pull out the j 22794, reinstall the spark plugs, and valve rocker arms.
