SYMPTOM/CONDITION

Oil leak at rear crankshaft (rope type) oil seal due to rotated upper oil seal.

DIAGNOSIS

Verify that the leak is at the rear crankshaft seal.

REPAIR PROCEDURE

This procedure insures that the protruded section of the seal is properly formed and has no frayed edges.

1. Remove oil pan.

2. Remove oil pump.

3. Remove rear crankshaft bearing cap.

4. Inspect upper seal half to see if it has rotated. Rotation of the seal will result in a gap at the right side of the main bearing cap and block parting line (Figure 1). If a gap is apparent, DO NOT REMOVE UPPER SEAL HALF. LEAVE IT IN THE BLOCK.

5. Remove the lower seal half from the main bearing cap.

6. Install the new lower seal half in the cap. Cut the right bank side flush with the cap surface. Remove the rope and rotate it so that the cut end protrudes above the surface the same amount it is short in the block half. Re-press the rope and cut the left bank side flush with the cap surface.
7. Lightly oil the lower seal half with engine oil.

8. Install the side seals making sure that the seal identified with yellow paint is installed on the right side.

9. Install the rear bearing cap, being careful not to crimp the long side of the oil seal between the cap and block.

10. Lightly oil, install, and torque the main bearing cap bolts to 85 foot pounds (115 N-m).

11. Reinstall the oil pump.

12. Reinstall the oil pan.

13. Check for oil leaks.
