Function of the Rear Crankshaft Seal

The rear crankshaft seal (rear main seal) prevents engine oil from leaking where the crankshaft exits the rear of the engine block to connect with the flywheel and transmission. It must seal against a spinning surface while withstanding heat and oil pressure. A leaking rear main seal causes oil drips, oil on the clutch or flywheel, clutch slippage, and a burning oil smell. Replacement typically requires removing the gearbox, making it a significant but essential repair.
