FILE IN S.I. Man. VOL. I

SEC. B-2 PG. 15
ISSUE: 01/89-1107
SUBJECT: CORRECTING ENGINE OIL LEAKS

APPLICATION: 1986 TO MID-88 9000 MODELS
Several running changes have taken place during the 1988 model year which help reduce the likelihood of engine oil leaks in 9000 cars. These changes include new components at the engine oil dipstick, the timing cover and the oil level sender. Installing these new parts on 1986 to Mid-88 9000's as described below will be effective in correcting and preventing oil leaks.

FIGURE 1 - THE NEW RUBBER-COATED STEEL TIMING COVER GASKETS.:

Timing Cover Gaskets

Beginning with Engine No. K025250, the fiber gaskets used to seal the timing cover have been replaced by rubbercoated steel gaskets Figure 1.

Timing cover gasket P/N 91 17 847
Timing cover gasket P/N 91 17 839

Use the gaskets listed above for all work required to repair oil leaks at the timing cover.

FIGURE 2 - AN IMPROVED O-RING IS AVAILABLE FOR THE OIL LEVEL SENDER.:

Oil Level Sender

An improved O-ring is available for sealing the oil level sender in the oil sump.

O-ring P/N 80 46 625

After removing the level sending unit, clean off any metal shavings and inspect the sealing surfaces for damage. Apply a light coat of grease to the new O-ring and install the sender in the oil pan.
New Oil Sump-to-Engine Sealant

A new, high-performance silicone sealant, Permatex Ultra Blue, has been introduced into production to seal the joint between the engine and the oil sump.

This sealant is available from jobbers and should be used for repairs any time the oil sump is removed from the engine.

FIGURE 3 - THE IMPROVED NIPPLE FOR THE DIPSTICK TUBE.:

Engine Oil Dipstick Tube

An improved dipstick tube nipple is available (Figure 3).

Dipstick tube nipple P/N 91 12 475

A new dipstick tube (P/N 93 88 794) should be used in conjunction with the new nipple. Attempts to remove the old tube usually result in damage to the tube, making it unusable in any case.

Apply a soft sealer, such as Permatex Ultra Blue, between the dip-stick tube and the nipple, and push the tube over the nipple. Install a new O-ring (P/N 21 96 772) into the groove on the nipple. Apply a light coat of grease to the O-ring and install the nipple into the oil pan.
