Why does the crankshaft seal keep failing?
The crankshaft rear seal fails repeatedly on the same car almost always because of elevated crankcase pressure — from a worn engine blowing past piston rings. If the PCV system cannot handle the blow-by volume, crankcase pressure exceeds the seal's designed holding capacity. GarageNation diagnoses and corrects the crankcase pressure before replacing the seal.
What is the difference between front and rear crankshaft seals?
The front seal is behind the crankshaft pulley/damper and is usually accessible after removing the serpentine belt. The rear seal is between the engine and gearbox and requires gearbox removal for access. Rear seal replacement ₹18,000–₹35,000 (more labour) vs front seal ₹8,000–₹18,000.
