Problem
OIL LEAK FROM CRANKSHAFT REAR OIL SEAL
Cause
- Ineffective sealing between seal and housing due to machining irregularities.
- Seal lip wear due to lack of lubrication between seal and crankshaft.

A modified oil seal is now available with improved outer sealing capabilities and a re-designed seal lip to improve seal to crankshaft lubrication. Modified seal (part number LUF100560L) must only be fitted using recently introduced sealant STC4171.
