RTV silicone sealant is used as a gasket between the
valve cover and cylinder head. Refer to page 2.3 for a
listing of approved sealants.
NOTE: Always use fresh sealant. Using outdated
sealant can result in leakage. Refer to Section
2 Tools & Aids for information on the sealant
dispenser.
1. Prepare the sealing surfaces of the cylinder heads
and valve covers following Service Bulletin 252
(or refer to page 9.1). The flatness of the sealing
surface must be checked prior to reinstallation.
See Section 9.
2. Apply a 1.5 mm (1/16 in.) bead of sealant to the
valve cover as shown in Figure 10-54.
NOTE: To ensure proper adhesion of the sealant
to both sealing surfaces, perform Step 3
immediately (5 minutes maximum) after
application of RTV.
3. Position the covers on the cylinder heads. If a
pulse style fuel pump is used the valve cover
with the pulse fitting hole must be installed on
the #2 side. Install the four hex flange screws in
each cover and finger tighten.
4. Torque the valve cover fasteners to 6.2 N·m
(55 in. lb.), using the sequence shown in Figure
10-55.
