Car Oil Leak in Sharjah — Causes, Warning Signs & Fix
An oil leak left unaddressed can lead to catastrophic engine failure. Whether it's a slow seep from an old gasket or a sudden loss of pressure, JAS Auto Workshop in Sharjah accurately diagnoses the source of every oil leak and fixes it properly — not with sealant or a temporary patch.
Common Causes
- Valve cover gasket degradation — the most common oil leak on most cars
- Rear main seal failure — oil drips from between engine and gearbox
- Oil pan gasket leak
- Camshaft and crankshaft seal failure
- Oil filter housing seal or O-ring failure
- Turbocharger oil feed line leak
- PCV (positive crankcase ventilation) system fault causing pressure buildup
- Cracked or corroded oil pan from road debris
Warning Signs
- Dark oily patches or puddle under the car after parking
- Burning oil smell from the engine bay (oil dripping onto hot components)
- Oil level dropping between services
- Blue smoke from the exhaust (oil burning in combustion chamber)
- Low oil pressure warning light (severe leak — stop immediately)
- Visible oil residue around valve cover, engine block, or undercarriage
What to Do Right Now
- 1. Check your oil level immediately — if low, top up with correct grade before driving
- 2. Never ignore a low oil pressure warning light — pull over and switch off the engine
- 3. Note where the leak is coming from (top of engine, bottom, front, or rear)
- 4. Avoid parking over clean surfaces to monitor leak rate
- 5. Book an inspection at JAS Auto Workshop — we identify the exact source before quoting
How We Diagnose & Fix It
- 01 UV dye leak test to pinpoint exact source of oil leak
- 02 Replace faulty gaskets or seals (valve cover, rear main seal, oil pan, camshaft seals)
- 03 Clean surrounding area to verify the repair has stopped the leak
- 04 Check PCV system for pressure faults that cause seals to blow
- 05 Inspect turbocharger oil lines if applicable
- 06 Top up oil to correct level and verify no pressure fault codes
- 07 Road test and re-inspect after running temperature to confirm seal

Frequently Asked Questions
- How much does fixing an oil leak cost in Sharjah?
- A valve cover gasket replacement costs AED 400–900. A rear main seal replacement costs AED 700–2,500 depending on the vehicle (requires gearbox removal on some models). An oil pan gasket costs AED 500–1,200. JAS provides a written quote after inspecting the source.
- Is an oil leak serious?
- Yes. A slow leak becomes a fast leak, and running low on oil causes catastrophic engine damage. Even a small oil leak should be repaired promptly — it's far cheaper than an engine rebuild.
- Can I use an oil stop-leak additive?
- Stop-leak additives swell seals temporarily and can work for very minor weeping gaskets. However, they don't fix damaged or hardened seals and can cause issues in certain engines. JAS recommends a proper mechanical repair over chemical additives.
- How do I know if my car has an oil leak?
- Check for dark stains or puddles under your car after parking overnight. Check the oil level regularly between services. A burning smell when the engine is warm is another sign — oil dripping onto hot exhaust components has a distinctive acrid smell.
