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

  A: A complete set of tools needed for valve service repair includes Spark Plug port adapter j 22794, valve spring compressors j 38606 and j 5892-d and valve guide seal installer j 42073. Enter the Spark Plug port adapter (J 22794) into the Spark Plug hole first and connect the air hose to apply compressed air before starting the job. Fasten a flat washer then put bolt and Rocker Arm onto the removed parts for the valve spring to be taken out. Take safety measures when working with compressed valve springs because their high tension presents danger to you. Set the valve spring compressor's (J 5892-D) slotted end under the washer on the Rocker Arm bolt. Apply slow and continuous pressure until access to valve keys is possible. Turn to the valve spring compressor (J 38606) tool when whole valve spring pressing fails. Release valve tension through the valve compressor tool before taking out the valve keys and detecting components. First remove the valve spring cap and valve spring pieces then take off the valve guide seal from its location. Apply clean engine oil to both valve stem and guide before selecting the right seal. Press it onto the valve stem. Put the valve guide seal installer (J 42073) on to position the seal on the valve guide leaving a space of 1 - 2 mm. Reinstall the valve spring components after you compress the valve spring with the valve spring compressor j 5892-d or j 38606 when needed. Press the valve stem keys firmly against the valve stem using grease support and let spring pressure ease down while keeping the keys in place. Examine if the valve stem keys now sit flat inside the spring cap and tap the stem when needed before taking out the Spark Plug port adapter (J 22794). Reinstall the spark plugs and valve rocker arms last.
