What is an engine overhaul?

Your engine works hard, and over time its parts wear out. An engine overhaul replaces those worn parts and gives the engine a new lease of life, so your car runs like new again. It is a way to save the engine you already have rather than swap in an unknown second-hand one.

Signs you may need an engine overhaul

Watch out for these warning signs:

  • White or blue smoke from the exhaust
  • The engine overheating
  • Loud knocking noises
  • The car burning through oil
  • A clear loss of power when driving

If your car shows these signs, it is worth acting early. Waiting usually turns a manageable repair into a bigger, more expensive one.

Why overhaul instead of replace?

A full engine swap can seem like the easy option, but it is costly and you lose the original engine that came with your car. An overhaul usually costs less, keeps your own engine, and avoids the risk of a second-hand unit failing down the road.

The benefits of a proper overhaul

A well-done overhaul means better mileage, smoother running, lower fuel use and cleaner emissions. Your engine lasts longer, your running costs drop, and the car holds more value when you sell it.

How much does an engine overhaul cost in Singapore?

Prices start from around S$3,500 for smaller engines and rise for larger or high-end models, some past S$10,000. The final figure depends on the engine and how worn it is. We check the engine first, then give you a clear, itemised quote and explain every cost before any work begins. Every engine overhaul is backed by our 3-year or 60,000km warranty, the longest engine warranty in Singapore.

Our engine overhaul process

  1. A full engine check and diagnosis
  2. Stripping the engine down
  3. Deep cleaning the parts
  4. Replacing what is worn or damaged
  5. Reassembling to specification
  6. Road testing to confirm a smooth drive

We keep you updated throughout, so there are no surprises.

How long does it take?

Most engine overhauls take 5 to 7 days, a little longer for some premium models. We will not rush the job. We focus on getting it right, so you drive off with peace of mind.

Talk to us before it gets worse

If your engine is showing the signs above, do not wait for a breakdown. See our full engine overhaul service page for details, or message us on WhatsApp with your car and the symptoms for an honest read and a clear quote. Acting early could save you thousands.
