The next step depends on what the car is doing now. Our car computer diagnostic service can support faults involving warning lights, sensors and control systems. Tell us the vehicle model and symptom; we will identify the tests that matter.
Do not keep restarting a severely overheated, oil-starved, knocking, or water-ingested engine. Repeated attempts can increase internal damage and the final repair cost.
A free initial inspection at our Al Quoz 4 workshop covers your concern and visible engine condition. A fault-code scan or focused mechanical test is separate when needed; we explain the test and its price before doing it. The ranges below are market-based planning estimates before VAT, not fixed prices for every vehicle. 5% VAT is not included in the displayed prices. They cover the work described in each row. The final written quote identifies parts, labor, any extra testing and the total before paid work begins.
| Engine service | Estimated total before VAT | What the estimate covers | Typical workshop time |
|---|---|---|---|
| Initial workshop inspection | Free | Review of the complaint, visible leaks and fluid condition, warning lights and basic condition. Computer scanning, dismantling and specialist testing are separate. | Confirm when booking |
| Engine fault-code scan and initial checks | AED 145 to 335 | Scan of relevant fault memory, code review and focused basic checks. Compression, leak-down, borescope or extended diagnosis is quoted separately if needed. | 45 to 90 minutes for the stated checks |
| Confirmed ignition or minor running repair | AED 335 to 1,715 | Installation of a confirmed faulty plug, coil, sensor, hose or similar accessible item, with a running check. Additional tests or multiple failed parts change the total. | Often same day if parts are available |
| Oil leak repair | AED 430 to 3,335 | Accessible seal or gasket replacement, cleaning, necessary fluids and a leak recheck. Access and additional leaks can change the work. | 4 hours to 2 days |
| Cooling and overheating repair | AED 525 to 4,285 | Pressure testing and the confirmed radiator, thermostat, pump, hose or related repair, with coolant service and a temperature check as required. Internal engine damage is separate. | Same day to 3 days |
| Head gasket or cylinder-head repair | AED 2,665 to 8,095 | Strip-down, head assessment, gasket set, bolts, machining where required, fluids and reassembly checks. A cracked head or block can change the decision. | 3 to 7 working days |
| Engine rebuild or overhaul | AED 6,190 to 20,950+ | Measured dismantling, required machining and internal parts, seals, reassembly and installed testing. The parts list follows measurement. | 7 to 20 working days |
| Used or remanufactured engine replacement | AED 5,240 to 28,570+ | Compatible engine unit, removal and installation, necessary fluids, supported adaptation and final checks. Engine provenance and availability matter. | 3 to 10 working days after sourcing |
What changes the cost: engine size and access, internal damage, machining, parts specification, supplier availability and related cooling or lubrication faults. We quote any further diagnosis or work found after dismantling before it proceeds.
Best when testing identifies a contained fault and the engine’s core mechanical condition is healthy. Common work includes ignition repairs, injector service, intake leaks, cooling components, oil seals, timing-related repairs and cylinder-head work. This option normally preserves the original engine and avoids unnecessary dismantling.
Choose it when: compression and oil pressure are acceptable, contamination is limited and the repair cost is reasonable compared with the car’s value.
Best when the original engine is valuable, compatible replacements are uncertain, or measured internal wear can be corrected properly. The engine is dismantled, cleaned and measured. Required bearings, rings, seals, gaskets and damaged parts are replaced, while machining is completed only where measurements require it.
Choose it when: the block and main castings are usable and there is a defensible parts and machining plan.
Best when the existing unit is seized, cracked, heavily overheated or uneconomical to rebuild. A replacement may be used, remanufactured or new. Compatibility, engine code, electronics, accessories, condition and supplier terms must be checked before purchase.
Choose it when: a traceable compatible unit offers a better total cost, timeline and risk than rebuilding the damaged engine.
Switch off safely. Do not keep restarting an overheated, oil-starved or water-ingested engine.
Monitor the gauges and fluid levels. Avoid long trips and hard acceleration until the cause is checked.
| What you notice | Possible causes | How serious? | Useful next check |
|---|---|---|---|
| White exhaust smoke and coolant loss | Head gasket, cracked head, coolant entering a cylinder or, on some engines, another coolant-fed component | High | Cooling pressure test, combustion-gas check and compression or leak-down testing |
| Blue smoke or high oil use | Turbo seals, valve-stem seals, piston rings, PCV fault or external leak reaching hot parts | Medium to high | Leak inspection, PCV and turbo checks, spark-plug reading, compression and leak-down tests |
| Knocking or low oil pressure | Low oil level, wrong oil, worn bearings, blocked pickup, oil pump fault or internal damage | Critical | Stop engine, verify oil level, measure mechanical oil pressure and inspect the filter or sump |
| Misfire and rough idle | Plug, coil, injector, air leak, carbon buildup, low compression or timing issue | Varies | Scan live data, isolate the cylinder and test ignition, fueling and compression |
| Overheating | Leak, fan issue, thermostat, water pump, restricted radiator, trapped air or internal sealing fault | High | Pressure test, fan activation check, temperature comparison and coolant-circulation assessment |
| Loss of power | Boost leak, turbo fault, fuel delivery, blocked exhaust, sensor error, timing deviation or low compression | Varies | Scan under load, smoke-test intake, review fuel and boost data, then test mechanical condition |
The same symptom can begin in different areas. These six inspection zones help explain why testing comes before a repair or parts decision.
The free first workshop inspection reviews your description, warning lights, fluids, leaks, belts, hoses and visible damage. We only road test when it is safe; any paid scan or deeper test is explained first.
Depending on the fault, checks may include diagnostic scanning, live data, cooling pressure, smoke testing, fuel pressure, mechanical oil pressure, compression, cylinder leak-down, borescope inspection or oil-filter examination.
We compare the findings with the engine design and explain whether a focused repair, rebuild or replacement is supported. You receive the proposed parts, labor, VAT-inclusive total and any conditional work before approval.
A lean-mixture code can come from an intake leak, weak fuel supply or incorrect sensor reading. A cylinder-misfire code does not automatically mean a coil is defective. Replacing the named part without testing the circuit and mechanical condition can waste money and leave the original problem unresolved.
Replacing only the head gasket can fail if a warped head, cracked casting, blocked radiator, weak fan, damaged water pump or earlier coolant contamination is missed. We check the cooling system and the consequence of the overheat together.
White vapor can be normal condensation, while persistent white smoke with coolant loss points toward internal coolant entry. Blue smoke can come from turbo seals, valve seals, rings or a crankcase-ventilation fault. Testing determines which repair is justified.
A failed pulley, tensioner, compressor or flywheel can sound like internal engine damage. Listening tests, belt isolation and oil-pressure checks help prevent an unnecessary rebuild or replacement.

Call or WhatsApp with the model and a short description. Choose a workshop visit, free pickup and delivery, or ask whether an on-site inspection is suitable.
After the free first inspection, we explain any paid scan or mechanical test. Your written quote separates the intended repair, parts, labor, VAT and work that depends on dismantling.
No major repair begins until you approve the work. If dismantling reveals additional damage, the revised finding and cost are discussed first.
Specified tightening procedures, sealing surfaces, fluids and timing references are followed for the approved work. Related components are checked while access is available.
Final checks may include leak inspection, temperature monitoring, oil-pressure confirmation, fault-code review, adaptation and a controlled road test.
You receive a clear summary of the completed repair, the parts fitted, and practical running-in or follow-up guidance when it applies. Ask any remaining questions before collection or free delivery.
Direct-injection petrol engines can develop injector, high-pressure fuel, carbon, ignition and crankcase-ventilation faults. Turbo engines also need boost-leak, lubrication and charge-air checks. When a turbo fails, the intake, intercooler, oil feed and exhaust side must be assessed so debris or restricted oil supply does not damage the replacement.
Timing-chain noise, variable-valve timing faults and oil-pressure issues should be tested early. A timing code can reflect a sensor or control issue, but it can also warn of mechanical wear that should not be ignored.
Diesel power loss or smoke may involve injectors, boost control, EGR, particulate filtration, compression or fuel pressure. Diagnosis should separate an emissions-system restriction from an internal engine fault before dismantling.
Hybrid vehicles require safe isolation awareness and model-specific procedures because the combustion engine operates with high-voltage systems and may start automatically. Engine-related work must consider cooling loops, electronic controls and hybrid operating conditions.
A targeted diagnosis usually costs far less than replacing multiple parts by guesswork. Ask what the test will prove and how it changes the repair decision.
For rebuild and replacement options, compare the engine unit, machining, labor, fluids, seals, programming, related cooling work and follow-up checks. A low unit price is not the installed total.
Genuine, OEM-quality, aftermarket, used and remanufactured parts have different costs and risks. The suitable choice depends on the component, vehicle value, intended ownership period and supplier support.
DIY checks should be limited to safe basics such as noting warning lights and checking fluid levels when the engine is cold and the owner’s manual permits it. Internal timing, compression diagnosis, overheating teardown and engine lifting require workshop equipment and technical procedures.
A rebuild becomes a serious option when testing confirms internal wear or damage across multiple cylinders, bearings, pistons, rings or sealing surfaces. Compression, leak-down, oil-pressure, borescope and dismantling measurements guide the decision. A single failed external component does not justify an overhaul.
We can give a planning range when you share the model and symptom. All displayed price ranges and example totals exclude 5% VAT. The free first inspection may identify the next step; a computer scan or deeper test is separately priced if needed. The written quote confirms the work and payable total before it begins.
It depends on the condition and traceability of the replacement, compatibility, installed total and the rebuild potential of your original unit. A cheaper used engine can become expensive if its engine code, electronics or condition are not checked. We compare both routes when they are viable.
A typical rebuild may take 7 to 20 working days. The timeline depends on dismantling findings, machining, parts availability and reassembly testing. Simpler cylinder-head work may be faster, while uncommon or performance engines can take longer.
We assess petrol, diesel, turbocharged and selected hybrid vehicle engine concerns across many European, Japanese, American, Korean and other makes. The recommended repair depends on model-specific tooling, information, parts and the engine’s condition.
Yes. Free pickup and delivery are available. Tell us if the engine overheated, lost oil pressure, makes a heavy knock or cannot run, so the vehicle can be handled safely. Do not restart a severely damaged engine simply to move it.
The free initial workshop inspection reviews your complaint, visible leaks, fluid condition, warning lights and basic engine condition. It does not include a computer scan, compression testing, dismantling or specialist tests. If those are needed, we explain the charge and ask for approval first.
Our dedicated inspection van can help assess some problems on-site. Major engine repairs, rebuilds and replacements normally require workshop lifting, measuring, cleaning and testing equipment. The first assessment determines the safe next step.
Send your car model and the symptom. We will help you choose a workshop visit, free pickup and delivery, or a suitable on-site inspection. You do not need to diagnose the fault before contacting us.
