An engine overhaul is major surgery for your car. The engine is opened up, worn internal parts are machined or replaced, and everything goes back together to factory tolerances. Done properly, it adds years of life to a car you already know and trust — at a fraction of what an engine replacement or a new car would cost.
At Motor & Mechanix, we handle complete engine overhaul and restoration in Noida for all major brands — petrol, diesel and CNG. Every job starts with a proper diagnosis, and you get a written estimate before we touch a single bolt.
Signs Your Car Needs an Engine Overhaul
- White or blue smoke from the exhaust — usually oil burning past worn piston rings or valve seals
- Engine oil level dropping between services, needing frequent top-ups
- Knocking or tapping sounds from inside the engine
- Clear loss of power and pickup, especially uphill or with the AC on
- Repeated overheating even after cooling system repairs
- Milky or sludgy oil on the dipstick — a possible head gasket failure
- Low compression readings across cylinders
One of these alone doesn't always mean an overhaul. Two or three together usually do. Bring the car in — a compression test tells us the truth quickly, and we'll show you the numbers.
Top Overhaul vs Full Engine Overhaul
Top overhaul (half engine work): we work on the cylinder head — valve grinding, valve seals, head gasket, and head skimming if the surface has warped. The right choice when the problem sits in the head and the engine block is still healthy.
Full engine overhaul (full engine work): a complete teardown. Pistons, rings, bearings, crankshaft, cylinder boring and honing — everything inspected and brought back to specification. Needed when wear has reached the block.
Not sure which one your car needs? That's exactly what the diagnosis stage is for. We never recommend a full overhaul when a top overhaul will do the job.
What Our Engine Overhaul Includes
- Complete engine teardown and inspection
- Cylinder boring and honing (rebore) where required
- New piston rings or pistons, depending on wear
- Crankshaft inspection, grinding and new bearings
- Cylinder head work — valve grinding, new valve seals, head skimming
- New gaskets, oil seals and O-rings throughout
- Timing belt or chain and tensioner check, replaced if due
- Oil pump and water pump inspection
- Fresh engine oil, oil filter and coolant
- Post-assembly tuning and road test
How We Do It — Step by Step
- Diagnosis. Compression test, visual inspection and computer scan to confirm the engine actually needs internal work.
- Written estimate. An itemised quote covering parts, machining and labour. Nothing starts until you approve it.
- Teardown and machining. The engine is stripped, measured, and machined to manufacturer specifications.
- Rebuild with genuine parts. Bosch, Hyundai Mobis and OEM-spec components. With 25,000+ parts in stock, your car isn't stuck waiting for weeks.
- Testing and handover. Idle tuning, road test, and a walkthrough of everything we replaced — with simple running-in advice for the first 1,000 km.
Engine Overhaul or Engine Replacement?
An overhaul keeps your original engine, so there's no RTO paperwork for a new engine number, and no gamble on the unknown history of a used replacement engine. A replacement only makes sense when the block itself is cracked or damaged beyond machining. We'll tell you straight which side your car falls on — and if an overhaul isn't worth it for your car's age and value, we'll say that too.
Engine Overhaul Cost in Noida
There's no honest way to put one fixed price on an overhaul — a top overhaul on a Maruti hatchback and a full rebuild on a diesel SUV are very different jobs. The final cost depends on engine size, how far the wear has spread, and which parts need machining versus replacement. What we promise: a clear written estimate after inspection, genuine parts listed on the invoice, and no surprise additions. In most cases a proper overhaul costs a fraction of an engine replacement, and far less than the down payment on a new car. And once the engine is rebuilt, staying regular with periodic car service is what protects that investment.
All Brands. Petrol, Diesel and CNG.
We overhaul engines for Maruti Suzuki, Hyundai, Honda, Toyota, Tata, Mahindra, Kia, Volkswagen, Skoda, Ford, Renault, Nissan, MG, Jeep and more. CNG-driven cars in particular tend to need valve and head work earlier than petrol — if your CNG car has lost pickup or started overheating, don't ignore it.

Frequently Asked Questions
It depends on the engine and the extent of internal wear. A top overhaul (cylinder head work) costs significantly less than a full rebuild with boring and new pistons. We give you an itemised written estimate after inspection, before any work begins — and an overhaul is almost always far cheaper than replacing the engine.
A top overhaul usually takes 2–3 working days. A full engine overhaul typically takes 4–7 working days, depending on machining work and parts. Because we stock 25,000+ parts, most jobs don't get stuck waiting for components.
Usually, yes. An overhaul keeps your original engine, so there's no RTO endorsement for a changed engine number and no risk from a used engine with unknown history. Replacement only makes sense when the block is cracked or damaged beyond repair — and we'll tell you honestly if that's the case.
A properly done overhaul restores compression, power and oil consumption close to original levels. Drive gently for the first 1,000 km or so while the new components bed in. The result depends heavily on part quality and machining precision — which is exactly why we use genuine parts and measure everything to specification.
White or blue exhaust smoke, oil disappearing between services, knocking sounds, loss of power, repeated overheating, or milky oil on the dipstick. If you're seeing two or more of these, get a compression test done before the damage spreads — it's a quick check and it removes the guesswork.
A second opinion costs you nothing
