VALVE BODY ASSEMBLY
1. Disassemble the main valve body assembly
using Figure 117 as a guide.
2. Lay each valve line-up out in order as you
remove them from the valve body casting.
3. Inspect each valve, valve spring, bore plug
and retainers for any wear and/or damage.
Replace complete valve body as necessary.
4. Clean all valve body parts thoroughly and dry
with compressed air.
5. Install each valve train back into their bores
exactly as shown in Figure 117, lubricating
them with Mercon V® as they are installed.
6. Refer to Figure 118 for the exact placement of
retaining pins and clips, as some of them are
installed inboard in the worm tracks of the
valve body casting.
7. Extra care here will eliminate some of the
troublesome problems encountered later.
