SUBJECT:
OIL PAN CRACKING DUE TO INCORRECT ENGINE LIFTING
- USE PROVIDED LIFTING PROCEDURES

MODELS/YEARS:
1987-92 ALL VEHICLES
WITH 2.3L (VIN A, D, 3) ENGINE





Field returned oil pans indicate damage and/or cracks have occurred when supporting or lifting the engine at the oil pan with jacking equipment or when applying pressure to the side of the pan (such as in prying on the pan to align mounts).

The only recommended method to support or lift the engine for front cover or other repairs where the front of the engine needs to be supported or lifted, is to use engine support fixture J 28467-A. Use of any other method is not recommended!

However, if J 28467-A is not available and the engine is being supported or lifted by the oil pan, a 2" x 4" block of wood must be used between the oil pan and the jacking equipment to avoid cracking the oil pan. Be sure the 2" x 4" block of wood extends beyond the edges of the oil pan to provide an even load distribution across the oil pan. Refer to the illustration.

DO NOT LIFT VEHICLE BY THE OIL PAN; this will cause the oil pan to crack. Refer to Section 0A of the applicable service manual for lifting and jacking points and procedures.
