Oil at the lower bellhousing area can prompt inspection, but leakage from higher on the engine or another nearby joint must be ruled out before identifying the rear main seal as the source.\u003c\/p\u003e\u003cp\u003eOn a manual-transmission vehicle, oil that reaches the clutch friction surfaces may contribute to clutch contamination or slipping. Inspect affected clutch components separately. Also check crankcase ventilation and operating pressure, because an unresolved ventilation fault can contribute to recurring leakage after seal replacement.\u003c\/p\u003e\u003ch3\u003eInstallation and service notes\u003c\/h3\u003e\u003cp\u003eFollow the engine-specific transmission, flywheel\/flexplate and sealing-flange removal procedure. Support the drivetrain correctly and inspect the crankshaft sealing surface and block mating face before installation.\u003c\/p\u003e\u003cp\u003eUse the prescribed alignment and installation tool to position the seal and flange without folding or damaging the sealing lip. Follow the instructions supplied with the actual seal design for preparation and lubrication; do not apply a generic oiling method to every rear-main-seal type.\u003c\/p\u003e\u003cp\u003eApply only the specified flange-joint sealant where the service procedure requires it, observe the prescribed tightening order and replace companion single-use hardware as directed.
