Engine Repair
Suitable when:
- Damage is limited to one or several components.
- Engine compression remains acceptable.
- Problems can be resolved without dismantling the entire engine.
For general repairs, visit our ‘Engine Repair’ page.
Engine Overhaul
Recommended when:
- Multiple internal components are worn.

What is an engine overhaul?
An engine overhaul involves dismantling, inspecting, repairing, and rebuilding internal engine components to restore performance and reliability.
How do I know if my engine needs an overhaul?
Signs include low compression, excessive oil consumption, persistent overheating, engine knocking, blue or white exhaust smoke, and repeated engine problems. A professional inspection is needed to determine whether an overhaul is the right solution.
Is an engine overhaul better than replacing the engine?

How long does an engine overhaul take?
The timeframe varies depending on the extent of the work required, parts availability, and your vehicle model. We'll provide an estimated completion timeline after inspecting your engine.
Do you perform engine diagnostics before recommending an overhaul?
Yes. Every engine undergoes comprehensive diagnostics, mechanical inspection, and testing before we recommend an overhaul or any major repair.
Does an engine overhaul include a warranty?
Eligible engine overhauls are covered by a repair warranty. We'll explain the warranty terms applicable to your vehicle before work begins.
