Performing both valve guide and valve stem oil seals along with valve spring replacement requires these tools:
Spark Plug port adapter (J 22794) and valve spring compressor (J 38606). You should start by taking off the
Rocker Arm and unwinding the Spark Plug wire boot at the Spark Plug one half turn before gently pulling it out. Heat-soak the engine until it touches room temperature then gently turn spark plugs 1 or 2 times before cleaning them with a brush or air compressor. Insert the Spark Plug port adapter (J 22794) into the Spark Plug hole and fit an air hose before pressing compressed air to stabilize the valves in their positions. Our valve spring compressor j 38606 tool lets you compress the spring before using tongs to remove valve stem keys (225) and slowly easing spring tension. Eject the valve spring compressor tool label j 38606 with all valve components. Remove the valve spring cap 224 and both valve spring 223 Valve Stem Oil Seal 222 then extract the valve 228. Place valves (228) into their correct position then install Valve Stem Oil Seal (222), valve spring (223), and valve spring cap (224) after cleaning the valve spring seat area of the Cylinder Head. Use the valve spring compressor j 38606 to press the valve spring then place valve keys in position using grease and validate they enter valve stem grooves correctly. Slowly let valve spring pressure pass through while keeping valve keys positioned and detach the valve spring compressor tool (J 38606). A plastic faced hammer taps helps seat the keys if they do not go into place by hand. After taking off the Spark Plug port adapter (J 22794), push down the Spark Plug by hand before fastening it at 15 n.m (11 lb ft). Check if the
Spark Plug Wires fit correctly on the
Ignition Coil and Spark Plug before putting back the Rocker Arm.
