Installation of the Oil Pan
Install as follows:
1. If the oil pump was removed, Refer to section "Installation of the Oil Pump, Oil Suction Manifold, and Oil Lines".
2. When a plastic oil pan is used, insert the raised lip portion of the seal into the groove in the oil pan. Press down on the
isolator seal and insert it completely around the oil pan. Be careful not to stretch or bunch the seal. For best results,
install the seal at each corner, then at points half way between the corners. Continue in this manner, halving the
distance and seating the seal.
3. For the aluminum oil pan, place the gasket on the top of the pan.
4. Apply a 5mm (0.2 in.) diameter bead of Loctite® 5970 or equivalent to the four corners circled below on the gasket.
5. Install the eighteen oil pan bolts and sleeve assemblies through the pan rail into the holes in the gasket.
6. Ensure the joint surfaces of the gear case, the cylinder block, and front cover are cleaned and there is no damage that
could prevent sealing.
NOTE: Oil pan (1) is Duraplastic. Oil pan (2) is Thermoplastic.
7. Install the oil pan assembly in position on the cylinder block.

NOTICE: Before torquing, bolt grade must be determined by a marking on the bolt head. Grade 8.8 oil pan bolts
cannot be torqued above 25 N·m (18 lb·ft) or damage to the bolt will occur.
NOTE: The corner bolts on the oil pan will be torqued twice, as each is marked with two numbers in graphic
below.
8. Ensure that the seal has not been disturbed. Torque the eighteen oil pan bolt assemblies using the proper sequence
shown below.
a. For a Duraplastic oil pan, torque bolts to 20 to 25 N·m (15 to 18 lb·ft).
b. For the aluminum and thermoplastic oil pans, torque bolts to 30 to 35 N·m (22 to 26 lb·ft).
9. Install the oil pan drain plug with a new O-ring and torque the plug.
