bearing cap (Fig. 66). DO NOT over apply sealant or
allow the sealant to contact the rubber seal. Assem-
ble bearing cap to cylinder block immediately after

(8) To align the bearing cap, use cap slot, align-
ment dowel and cap bolts. DO NOT remove excess
material after assembly. DO NOT strike rear cap
more than 2 times for proper engagement.
(9) Clean and oil all cap bolts. Install all main
bearing caps. Install all cap bolts and alternately
tighten to 115 N·m (85 ft. lbs.) torque.
(10) Install oil pump.
(11) Install the timing chain cover.
(12) Install the vibration damper.
(13) Position the connecting rods onto the crank-
shaft and install the rod bearing caps. Tighten the
nuts to 61 N·m (45 ft. lbs.).
(14) Apply Mopart Silicone Rubber Adhesive Seal-
ant, or equivalent, at bearing cap to block joint to
provide cap to block and oil pan sealing (Fig. 67).
Apply enough sealant until a small amount is
squeezed out. Withdraw nozzle and wipe excess seal-
ant off the oil pan seal groove.

INSTALLATION
(1) Install oil pump. During installation slowly
rotate pump body to ensure driveshaft-to-pump rotor
shaft engagement.
(2) Hold the oil pump base flush against mating
surface on No.5 main bearing cap. Finger tighten
pump attaching bolts. Tighten attaching bolts to 41
N·m (30 ft. lbs.) torque.
(3) Install the oil pan.
CRANKSHAFT OIL SEAL—FRONT
The oil seal can be replaced without removing the
timing chain cover provided the cover is not mis-
aligned.
(1) Disconnect the negative cable from the battery.
(2) Remove vibration damper.
(3) If front seal is suspected of leaking, check front
oil seal alignment to crankshaft. The seal installa-
tion/alignment tool 6635, should fit with minimum
