  Q: How to Install a Rocker Shaft Spring Kit on a GMC Sierra 1500?

  A:

  You need to take off the Rocker Arm before replacing both valve parts. Loosen each Spark Plug wire boot by turning it halfway while pulling on the boot alone. Loosen spark plugs from the Cylinder Head when engine is at room temperature before cleaning dirt with air or brush. Turn spark plugs one or two turns to detach them before brushing or air blasting them free. Set the j 22794 into the Spark Plug hole and secure an Air Hose while using compressed air to hold the valves stationary. Use tool (J 38606) to tension valve springs before taking out valve stem keys (225) and letting spring tension off slowly. Degas the engine by first taking out the valve spring compressor (J 38606), valve spring cap (224), valve spring (223), Valve Stem Oil Seal (222), and valve (228). Brush oils through the valve spring seat region of the Cylinder Head before applying clean engine oil on both the valve guide and Valve Stem Oil Seal. Put the valves (228) into the right port before setting the Valve Stem Oil Seal (222), valve spring (223), and valve spring cap (224). Use the (J 38606) tool to compress the valve spring before inserting the keys into their grooves on the valve stem and keeping them in place with grease. Lift valve spring pressure while monitoring key position. Then take out the tool and tap the valve stem tip with a soft-headed hammer to better place keys if needed. Apply the (J 22794) into the Spark Plug port and turn the key by hand until the plug fires. Then tighten the plug to 15 nm (11 lb ft). Push the spark plugs directly into their connections at the Ignition Coil and Spark Plug. Check wire installation by pressing each boot from side to side then replace any loose boots. Finally, install the Rocker Arm.
