OIL PAN REMOVAL
Carefully move the pipes to one side so they are to the left of the division between the engine and the transmission. Use tie straps or similar to hold in place.
If there is an oil thermostat, detach the cover with the oil line (the screws can be reached by bending the fender liner in the wheelhousing to one side).
Remove all the oil pan screws except for one at each corner.
Use a suitable tool at the marked points to pry apart the joint so the liquid gasket releases. Remove the remaining screws, work the oil pan sideways, and down to the left.
CLEANING
Wipe off oil and remove any gasket residue from the bottom engine surfaces using gasket solvent P/N 1161440-1. Scrape with a plastic scraper if necessary. Discard O-rings and install new rings
(NOTE: there are two types of O-ring).
If reinstalling the same oil pan, clean off using the same method. In addition, wash the pan in degreasing solvent and hot water internally and externally.
INSTALLATION OF OIL PAN.
Apply liquid gasket P/N 1161059-9 using a short-bristle roller P/N 9511205 on the oil pan.
Install oil pan, guiding the dipstick tube into its hole at the same time Use several of the screws to attach the oil pan loosely in place.
Install all the screws but do not tighten.
Press the oil pan against the transmission and tighten screws (1), (2), (3) and (4) to 2-3 Nm (1.5-2 ft. lbs). Tighten the screws (5) first to 25 Nm (18 ft. lbs) and then to 48 Nm (35 ft. lbs). Tighten the other screws starting from the transmission and working forward in pairs to 17 Nm (13 ft. lbs).
If there is an oil thermostat, reinstall using new gasket.
REINSTALL THE TORQUE ROD
Reinstall the torque rod using new screws and tighten to 35 Nm (26 ft.lbs) +60°, use protractor 951 2050.
Note! Early type M8 screw torque to 18 Nm (13 ft. lbs) +90°
Install nuts and tighten to 65 Nm (48 ft. lbs) +60°
Remarks: The screws can only be reused once, then they must be knocked out of the bracket and replaced with a standard screw with a head. The same tightening torque applies.
ATTACH THE OIL LINE TO THE STEERING SERVO
Remove the tie straps holding the oil lines. First reinstall the front clamp without tightening fully. Reinstall both the others with their brackets and tighten the pipe clamp screws only when the lines are correctly located in position.
Tighten the screw for the first clamp.
Install new oil filter (Older cars: Reinstall engine splashguard, if fitted) and lower car.
Top up engine oil level and reinstall the dipstick.
CHECK FOR LEAKS
Raise car and check for oil leaks from the servo line and oil pan.
