What Is the Camshaft Seal?
The camshaft seal is a small rubber lip seal that fits in the bore where the end of the camshaft passes through the cylinder head. Its job is to keep engine oil inside the head as the camshaft rotates. Despite being a small and inexpensive part, a failing camshaft seal requires significant disassembly to access: the timing cover must be removed, which means disturbing the timing belt or chain and associated components. In UAE workshops, camshaft seal replacement is almost always combined with a timing belt service for this reason.
Camshaft Seal Replacement Cost in UAE 2026
The table below covers typical prices for camshaft seal replacement across UAE certified garages in 2026, with and without a simultaneous timing belt service.
| Scope of Work | Parts Cost (AED) | Labour (AED) | Total Estimate (AED) |
|---|---|---|---|
| Camshaft seal only (SOHC engine) | 20 to 60 | 300 to 600 | 350 to 700 |
| Camshaft seals only (DOHC engine, both seals) | 40 to 120 | 350 to 700 | 420 to 860 |
| Cam seal + timing belt + tensioner (SOHC) | 150 to 350 | 350 to 650 | 550 to 1050 |
| Cam seal + timing belt + tensioner (DOHC) | 200 to 500 | 400 to 750 | 650 to 1300 |
| European vehicle (BMW, Mercedes, Audi, VW DOHC) | 200 to 600 | 500 to 1000 | 750 to 1700 |
Note: most UAE garages strongly recommend replacing the timing belt and tensioner whenever the timing cover is opened for cam seal work. The additional belt parts cost is modest versus the risk of leaving an aged belt in place, and it saves a second timing cover removal within a few years.
Why Camshaft Seal Replacement Often Includes a Timing Belt Service
The camshaft seal sits directly inside the timing cover, behind or adjacent to the timing belt sprocket. Replacing the seal requires removing the timing cover, which in turn requires removing the timing belt to access the seal bore properly. With the timing belt already off, replacing it costs only the price of the belt and tensioner in additional parts — the labour of removing and reinstalling it is effectively zero because it must be done anyway. On any timing-belt vehicle where the belt is within 10,000 to 20,000 km of its scheduled replacement, a combined camshaft seal and timing belt service is the most cost-effective approach.
What Affects the Cost of Camshaft Seal Replacement?
- Engine type (SOHC vs DOHC): DOHC engines have two camshafts and two seals. Most workshops recommend replacing both at the same time since the labour is shared.
- Timing belt vs timing chain: Timing-chain engines also have cam seals, but the chain itself is not typically replaced at the same time. The cover removal on chain engines can be more complex, increasing labour time.
- Water pump position: Some timing-belt engines have the water pump driven by the timing belt. If the water pump is accessible with the belt off, replacing it at the same visit avoids future timing cover re-entry.
- Vehicle make: European DOHC engines use more expensive OEM seals and carry higher workshop labour rates.
Signs That a Camshaft Seal Needs Replacement
- Oily seep or film on the timing cover or at the front of the engine
- Oil dripping from the bottom of the timing cover area
- Oil-saturated timing belt (urgent — indicates the belt may fail prematurely)
- Burning oil smell from the engine bay
