Remove Valve Cover and Cylinder Head

1. Remove the remaining hex. flange mounting
screws and any loose spacers (stamped steel
covers) from the valve cover. Note their placement/
orientation. Remove the valve cover from the
cylinder head assembly. See Figure 9-23 and 9-24.
NOTE: The valve cover is sealed to the cylinder
head using RTV silicone sealant. When
removing valve cover, use care not to
damage the gasket surfaces of cover and
cylinder head. To break the RTV seal,
hold a block of wood against one of the
flat faces of the valve cover. Strike the
wood firmly with a mallet. If the seal
doesn't break loose after 1 or 2 attempts,
repeat procedure on other side.

Disassemble Cylinder Head

Two basic styles of heads are used. The first style
utilizes a rocker bridge configuration as shown in Figure
9-26. The second style contains separate rocker arm
assemblies (with or without a guide plate), and either a
non-adjustable or adjustable valve lash configuration.
Variations of this style are shown in Figure 9-27.
Components are unique to each head configuration.
Follow the appropriate procedure based upon the
configuration involved.
NOTE: Before disassembly, determine the specific
head configuration involved, and mark all valve
train components to assure they are
reassembled on same side.
1. Remove the spark plug. See Figure 9-26.
