Service Procedure
1. Remove both valve covers. Refer to Workshop Manual (WSM), Section 303-01C.
CAUTION: Use a shop rag to prevent shavings from the drilling process from going into the
under side of the valve cover. Thoroughly clean the under side of each valve cover after drilling to
remove any shavings which may have entered into the under side of the valve cover. Any
shavings left in the valve cover when it is reinstalled on the engine may enter the engine and
cause damage to it.
2. Using a 10 mm (0.394 in) drill bit and drilling from the underside of the valve covers, drill holes through
the 5 tabs along the perimeter of the valve covers that do not already have holes. This will allow
fasteners to go through them. Use the indented area on each tab as a guide to center the drill bit to
make sure the holes are drilled in proper alignment to allow fasteners to pass through them and thread
into the corresponding holes in the cylinder head when the valve covers are reinstalled on the engine.

3. Reinstall the valve covers onto the engine, adding fasteners through the holes drilled in Step 2. Refer to
WSM, Section 303-01C. Follow the revised tightening sequence in Figure 2 for the left valve cover and
Figure 3 for the right valve cover. Tighten the fasteners to 10 Nm (89 lb-in).
