Car Crankshaft Oil Seal Replacement Cost in UAE (2026)
The crankshaft has two oil seals — a front seal at the timing cover end and a rear main seal at the gearbox end — that prevent engine oil from leaking past the rotating crankshaft. Crankshaft seal failure in UAE vehicles is accelerated by the extreme heat that causes rubber seals to harden, shrink, and crack faster than in cooler climates. A leaking crankshaft seal leaves an oil trail on the ground or oil accumulation on the underside of the engine, and in severe cases can drip oil onto hot exhaust components, creating a fire risk.
Crankshaft Oil Seal Replacement Costs in UAE (2026)
| Service | Cost (AED) |
|---|---|
| Front crankshaft seal replacement | 200-600 |
| Rear main seal replacement (manual gearbox) | 400-1,500 |
| Rear main seal replacement (automatic) | 600-2,500 |
| Crankshaft seal + timing chain service (combined) | 1,000-3,000 |
Crankshaft Seal Diagnosis in UAE
The front crankshaft seal is accessible when the timing cover is removed — typically done during timing belt or chain replacement. If the timing belt or chain is being replaced on a high-mileage UAE vehicle, replacing the front crankshaft seal at the same time (the seal costs AED 20-80 in parts) is highly cost-effective since the labour is already spent gaining access. The rear main seal requires gearbox removal — a significant labour cost. Confirm the source of an oil leak at the front of the engine (timing cover area) before assuming front seal failure, as the crankshaft position sensor O-ring and cam cover gaskets also leak from this general area.
