Quick answer

A complete engine overhaul at Metre Per Second in Hyderabad costs ₹45,000–₹2,50,000, set by cylinder count, whether the block needs a rebore and oversize pistons, and whether the head is repairable or must be replaced. Every job begins with a free compression and cylinder leak-down test so we can prove what is actually worn before quoting. An overhaul is the right call when you see measurable blow-by, oil consumption above one litre per 1,000 km, coolant in the oil, or a knock under load.

Hyderabad's Engine Overhaul Authority

Metre Per Second — Premium Car Service and Repair is Hyderabad's dedicated engine overhaul workshop. While general garages open an engine and start replacing parts on guesswork, we confirm the real condition first — compression test, cylinder leak-down, oil-sample analysis and an OEM-tool scan (BMW ISTA, Mercedes XENTRY, Audi/VW ODIS, Land Rover IDS5) — so you only pay for the rebuild your engine genuinely needs.

An engine overhaul is precision work. A top-end rebuild (cylinder head, valves, valve seals, head gasket, timing chain) fixes oil burn, white smoke, knocking and head-gasket failure; a bottom-end rebuild (pistons, rings, bearings, crankshaft, oil pump) fixes low compression, blow-by, oil consumption and rod knock. We have rebuilt both on K-series and VTEC petrols, CRDi/Multijet/mHawk/Kryotec diesels and German turbo platforms (B47, N47, OM651, EA288, EA888), so we machine to OEM spec and assemble it right the first time.

Over 15+ years and 25,075+ vehicles in Hyderabad, we have built our name on honest diagnosis, OEM-spec parts and a 1-year warranty covering engine, parts and labour. Free pickup and drop across KPHB, Kukatpally, Madhapur, Gachibowli and Banjara Hills means your car reaches our bay without you losing a working day.

What We Repair

Top-End Overhaul

Cylinder head removal, valve regrind or replacement, new valve stem seals, head gasket and timing chain — the fix for oil burn, white smoke, ticking and head-gasket failure on petrol and diesel engines.

Bottom-End Overhaul

Engine-out rebuild of pistons, rings, main and big-end bearings, crankshaft polish and oil pump — for low compression, blow-by, heavy oil consumption, low oil pressure and rod-knock.

Cylinder Head Reconditioning

Pressure-testing for cracks, crack repair, valve seat regrind, head skimming and new seals on B47/N47, OM651, EA888 and K-series heads — restoring flat sealing faces and compression.

Timing Chain & Belt Kits

Full OEM kits — chain, tensioner, guides, water pump and rollers — fitted with OEM timing tools. Critical on N47/B47 rattle and EA888 stretched-chain failures before they jump and bend valves.

Head Gasket Replacement

Head skim, new head bolts, coolant flush and pressure test to cure coolant loss with no visible leak, white exhaust smoke and oil-coolant mixing.

Carbon Clean & Diagnosis

Compression and leak-down testing, oil analysis, and walnut-blast carbon cleaning on direct-injection engines (TFSI, T-GDi, GDi) — often the cheaper fix we recommend instead of a full overhaul.

Our Repair Process

  1. Free Pickup & Vehicle Intake: We collect your car from anywhere in Hyderabad, log symptoms — smoke, knock, oil use, overheating — and confirm the engine platform before any work begins.
  2. Compression & Leak-Down Testing: A compression test (we act on >15% variance between cylinders) and a cylinder leak-down test (>20% leak indicates ring/valve wear) tell us top-end vs bottom-end before any disassembly.
  3. OEM Scan & Oil Analysis: We scan on the manufacturer's own platform (ISTA / XENTRY / ODIS / IDS5) and analyse oil for fuel and coolant contamination to confirm the real cause.
  4. Disassembly & Precision Measurement: The engine is pulled if needed; block and head are measured against OEM tolerances. We show you the worn parts with photos and video so you see exactly what failed.
  5. Fixed Quote & Your Approval: You get a clear, itemised, fixed quote. No machining or parts are ordered until you approve it — and if we find extra damage during teardown we call you first.
  6. Machining & OE-Spec Rebuild: Head skimmed and pressure-tested, valves reground, block honed where needed, then assembled with OEM or OE-equivalent pistons, rings, bearings, gaskets and seals, torqued to spec.
  7. Run-In, Coding & QC Road Test: Oil primed before first start, a controlled 30-minute run-in, OEM coding/adaptation, then a 50 km road test under load to confirm power, oil pressure and no leaks.
  8. Handover With 1-Year Warranty: Your car is delivered back clean, the job explained, with a 1-year warranty on engine, parts and labour and free re-checks at our KPHB workshop.

Why Metre Per Second

In-House Machining Bay

Head skimming, valve regrind and block honing happen under our roof, so quality, tolerances and timelines stay in our control instead of being outsourced.

Diagnose Before We Open

Compression, leak-down and oil analysis decide top-end vs bottom-end — many cars labelled 'overhaul' by other garages only need a timing chain or carbon clean, and we tell you the truth.

OEM Diagnostic Platforms

ISTA, XENTRY, ODIS and IDS5 — the same tools the dealership uses — so coding, adaptation and fault tracing are dealer-accurate after the rebuild.

OEM / OE-Grade Parts

Pistons, rings, bearings, gaskets, timing kits and seals from OEM suppliers — never the cheap rebuild kits that burn oil again within months.

Free Pickup & Drop

Doorstep collection across KPHB, Kukatpally, Madhapur, Gachibowli, Hi-Tech City, Banjara Hills and Jubilee Hills.

1-Year Warranty

Every overhaul is backed by a 1-year warranty on engine, parts and labour — proof we stand behind the work, often at 35–40% less than dealer cost.

Why Engine Overhaul Is Needed — Common Causes

Skipped Oil Services

The single biggest root cause. Going beyond 8,000 km between fully-synthetic oil changes destroys the cylinder honing, rings and bearings and leads straight to overhaul.

Hyderabad Stop-Start Traffic

Crawl traffic in KPHB, Madhapur and Gachibowli oxidises oil far faster than highway running, accelerating ring and bearing wear by 20–30%.

Summer Heat (45°C+)

Hyderabad's long summer thermally degrades conventional oil, forming sludge that starves the top-end of lubrication and bakes the rings.

Overheating Events

A single overheat from a failed thermostat, water pump or burst hose can warp the cylinder head, forcing a top-end overhaul within months.

Ignored Smoke & Knock

Driving on blue/white smoke or a rod-tap noise turns a top-end repair into a full bottom-end rebuild as the crankshaft journals get destroyed.

Coolant or Fuel in the Oil

A leaking head gasket or injector wash-down contaminates the oil, stripping its film strength and wearing every bearing surface at once.

How To Avoid Engine Overhaul — Prevention

Change Oil On Schedule

Use fully-synthetic OEM-spec oil and stick to a 8,000–10,000 km interval (sooner for hard city use). It is the cheapest insurance against an overhaul.

Act On Smoke & Noise Early

Blue/white smoke or a new ticking/knocking sound means get a compression test now — early top-end work is a fraction of a full rebuild.

Never Ignore Overheating

Stop and call us the moment the temperature gauge climbs. Driving an overheating engine warps heads and cracks blocks.

Replace Timing Chains On Time

On N47/B47 and EA888 engines, renew the timing chain kit at the recommended interval before it stretches, rattles and jumps.

Carbon Clean Direct-Injection Engines

Walnut-blast intake valves around 60,000 km on TFSI, T-GDi and GDi engines to keep compression and power up and avoid misfire-driven damage.

Watch Oil & Coolant Levels

Rising oil consumption or unexplained coolant loss is an early warning of ring or head-gasket wear — get it checked before it becomes a rebuild.

Recent Repairs at Our Workshop

EA888 Oil-Burn Cured Without Engine Swap

Skoda Octavia · 1.8 TSI (EA888)

Problem: Customer reported heavy oil consumption — about a litre every 2,000 km — and a dealer had quoted a long-block replacement.

Work done: A leak-down test confirmed worn piston rings, not a block fault. We removed the head, replaced the pistons and rings with the updated OE-spec parts, renewed valve stem seals and the PCV, and ran the engine in.

Outcome: Oil consumption back to normal at a fraction of the long-block quote, delivered with a 1-year warranty. (₹1,15,000)

N47 Timing Chain Caught Before It Jumped

BMW 320d · N47 diesel

Problem: Loud rattle on cold start and a chain-related fault on ISTA. The rear-mounted N47 chain was stretched and close to jumping — which would have bent valves.

Work done: Engine-out access to the rear timing case, full OEM chain kit fitted — chain, tensioner, guides and sprockets — timed with BMW tools, followed by oil and filter service.

Outcome: Rattle eliminated and a catastrophic valve-to-piston failure avoided, at around 40% less than the dealer estimate. (₹68,000)

OM651 Head Gasket & Top-End Rebuild

Mercedes-Benz E250 CDI · OM651 diesel

Problem: White exhaust smoke and unexplained coolant loss with no external leak — classic internal head-gasket failure.

Work done: Head removed and pressure-tested, skimmed flat, valves reground, new multi-layer head gasket and OEM head bolts fitted, coolant system flushed and the engine pressure-tested before reassembly.

Outcome: Coolant loss and smoke gone, compression restored to spec, road-tested under load and handed over with a 1-year warranty. (₹95,000)

Customer Reviews

★★★★★ Naveen Chandra, KPHB — Skoda Octavia 1.8 TSI

My EA888 was burning a litre of oil every 2,000 km. They proved it was the rings with a leak-down test, did a proper top-end with new piston rings and seals, and the oil burn is gone. Quote matched the invoice exactly.

★★★★★ Sandeep Reddy, Gachibowli — BMW 320d

The N47 timing chain was rattling at cold start. MPS scanned on ISTA, replaced the full chain kit with guides and tensioner, and saved my engine from a jumped chain. Dealer wanted nearly double.

★★★★★ Mohammed Faizan, Banjara Hills — Mercedes-Benz E250 CDI

White smoke and coolant loss on my OM651. They found a failed head gasket, skimmed the head, pressure-tested it and rebuilt the top end. Free pickup from home and a clear written quote. Genuinely dealer-level work.

★★★★★ Praveen Goud, Kukatpally — Maruti Swift K12

Knocking noise and low compression after I missed services. Full bottom-end rebuild with new pistons and bearings. Runs like new with a 1-year warranty. Very honest about what was actually needed.

★★★★★ Anitha Rao, Madhapur — Audi A4 2.0 TFSI

Loss of power and rough idle. Instead of a full overhaul they did a walnut-blast carbon clean and saved me a lot of money. Power is back. Refreshing to find a workshop that doesn't oversell.

★★★★★ Rajesh Varma, Jubilee Hills — Toyota Fortuner 1GD

High oil consumption and blue smoke on my diesel. They did a complete overhaul with OEM parts, primed and ran it in, then road-tested 50 km before handover. Transparent pricing and on time.

Technical terms explained

The engine overhaul terms that appear on our estimates, job cards and diagnostic reports — in plain English, written by the technicians who use them.

Timing chain stretch
Not literal stretching — it is cumulative wear on every chain pin and bush that adds up to extra chain length, so the camshafts fall behind the crankshaft. The ECU sees camshaft-to-crankshaft correlation drift and logs a P0016-family code, usually with a rattle for a second or two on cold start. Left alone the tensioner runs out of travel and the chain can jump a tooth, which on an interference engine bends valves.
Dual mass flywheel (DMF)
A two-piece flywheel with springs and a friction damper between the halves, fitted to absorb the torsional shock of a modern high-torque diesel before it reaches the gearbox. Free play beyond roughly 15 mm of rotational movement, or scorch marks and grease loss, means the damper is finished. A worn DMF rattles at idle with the clutch out, and replacing the clutch without it simply transfers the rattle to a new plate.
Blow-by
Combustion pressure escaping past worn piston rings into the crankcase instead of pushing the piston down. It shows up as oil mist from the filler cap, a pressurised crankcase, rising oil consumption and falling compression on a cylinder leak-down test. Once blow-by is measurable, honing and new rings — an overhaul — is the only real fix; additives do nothing for ring-to-bore clearance.
Rebore and oversize pistons
When cylinder bores are scored or worn oval beyond the service limit, the block is machined out to a larger diameter and fitted with pistons 0.25 mm or 0.50 mm oversize to restore the correct piston-to-wall clearance. The bore is then plateau-honed to a specific crosshatch angle so new rings bed in and hold oil. It is the difference between an engine that stops burning oil for another 150,000 km and one that smokes again within a year.

Frequently Asked Questions

How do I know if my engine needs an overhaul?

Watch for blue or white exhaust smoke, knocking or rod-tap noise, heavy oil consumption (over 1L per 5,000 km), coolant loss with no visible leak, low power under load, or a failed compression test. Any of these means you should get a compression and leak-down test before it worsens.

Do I always need a full overhaul, or can it be a smaller repair?

Not always. We run three tests first — compression (variance over 15% between cylinders), leak-down (over 20% leak), and an oil-consumption check. Many engines labelled 'overhaul' by other garages only need a timing chain, head gasket or a carbon clean. We recommend the cheapest fix that genuinely solves it.

What is the difference between a top-end and bottom-end overhaul?

A top-end overhaul covers the cylinder head, valves, valve seals, head gasket and timing chain — it fixes oil burn, white smoke and head-gasket failure. A bottom-end overhaul covers pistons, rings, bearings, crankshaft and oil pump — it fixes low compression, blow-by and rod knock. A full overhaul combines both.

How much does an engine overhaul cost in Hyderabad?

A compression/leak-down diagnostic is ₹1,500–₹3,500 (refundable against the job). Top-end overhauls run ₹35,000–₹1,80,000, bottom-end and full overhauls ₹65,000–₹3,50,000 depending on the engine and parts. You always get a fixed quote after a free inspection — typically 35–40% less than dealer prices.

Which engines do you specialise in?

Petrol: Maruti K-series, Hyundai Kappa, Honda VTEC, BMW B48/N20, Mercedes M274/M276, Audi EA888 TFSI. Diesel: Toyota 1GD-FTV, Mahindra mHawk, Tata Kryotec, Hyundai CRDi, BMW B47/N47, Mercedes OM651/OM654, Audi EA288 TDI. We also handle CNG (hardened valve seats) and hybrid engines.

Do you use genuine parts and proper tools?

Yes. We use OEM or OE-equivalent pistons, rings, bearings, gaskets and timing kits, and the manufacturer's own diagnostic platforms — ISTA, XENTRY, ODIS and IDS5 — so coding and adaptation after the rebuild are dealer-accurate.

How long does an engine overhaul take?

Top-end overhaul: 3–5 working days. Bottom-end overhaul: 5–8 working days. Full overhaul: 8–12 working days depending on parts availability and machining. We give you a clear timeline at the quote stage and send daily progress photos.

Is there a warranty, and do you offer pickup?

Yes — every overhaul carries a 1-year warranty on engine, parts and labour with free re-checks at our KPHB workshop. We also offer free pickup and drop across KPHB, Kukatpally, Madhapur, Gachibowli, Hi-Tech City, Banjara Hills and Jubilee Hills.
