Disassembly
Stamped Steel Valve Covers with RTV Sealant
1. Remove the four hex flange screws, or Torx
screws securing each valve cover.
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 the 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 the procedure on the other
side.

off the rocker arm adjusting nuts. See Figure 8-27.
3. Mark the location of the push rods as either
intake or exhaust and cylinder 1 or 2. Push rods
should always be installed in the same positions.
