IMPORTANT: Do not attempt to straighten or reuse the original oil pan. Replace the original oil pan with the new design.






11. When attempting to install the new oil pan P/N 21015428, minimal interference condition is likely to exist between the oil pan rail, flywheel and crankshaft bearing tie plate. To eliminate this condition, use a metal hand file to remove a small amount of material near the rear bolt hole of the oil pan. Refer to illustrations, for specific area of oil pan to modify.

NOTICE: Do not use an air driven grinder or other motorized tool. Removal of too much material may result in an oil pan leak.






12. File oil pan at area indicated in illustrations. Remove approximately 0.5 mm (.020 in.) of material.






IMPORTANT: The final filed edge of the oil pan will appear as shown in the illustration.

13. Make sure the oil pan surface is free of cured RTV and cleaned with a chlorinated solvent, such as carburetor spray cleaner, brake clean, or alcohol Saturn P/N 21007432 (or equivalent).

IMPORTANT: Minimal c]earance exists between the oil pan, crankshaft bearing tie plate and flywheel. Therefore, it is recommended that a trial assembly be performed without RTV prior to final assembly with RTV.

IMPORTANT: Assemble while the RTV is still wet (within three minutes). Do not wait for the RTV to skin over.






14. Apply a 4.0 mm (0.160 in.) bead of RTV in the oil pan groove, routing the RTV bead toward the inside of all bolt holes.
