REPAIR INSTRUCTIONS, PART 1
Make sure that the oil pan flange is flush with the
crankshaft front cover and block flanges in order
to prevent leaking.

Figure 312 — Flywheel Housing-to-Cylinder Block
Mounting Surface
Eighteen flange head screws with pressed-on
springs hold the oil pan to the bottom of the
cylinder block. Seventeen have a common
hexagonal head with integral washer. One screw,
similar to the others, also has a threaded stud on
its head. This screw is located third from the rear
on the left side of the cylinder block. Tighten the
screws in the sequence specified in Figure 313.
1. Install the oil level sensor into the oil pan.
Using a torque wrench, tighten the oil level
sensor to specification.
2. Install the engine oil fill adapter on the oil fill
port fitting of the oil pan and tighten to
specification.
3. Place the oil pan seal in position on the oil
pan flange. The two metal tabs on the inner
edge of the pan seal must always be
positioned at the front of the engine and the
single tab on the outer edge at the left rear
for both the front sump and rear sump
arrangements.
4. Make sure that the 12 locating pins on the
seal are properly seated in the locating
holes in the mounting flange.
Make sure the oil pan seal is properly placed
before tightening the screws.
5. Position the oil pan on the cylinder block.
