Engine Finders connects UK drivers with specialists for reliable, reconditioned MG Metro replacement engines. Whether battling the notorious head gasket failures in early A-Series Plus units or oil consumption issues in later K-Series variants, we provide direct OEM-spec solutions for the entire Metro series.
The MG Metro evolved through two distinct technical eras: the legendary A-Series Plus era (1982–1990) and the advanced K-Series era (1990–1994), often referred to as the Rover Metro/100 phase. Throughout this evolution, the series shared critical engineering DNA with the Mini and Maestro. A series-wide technical concern for A-Plus engines involved the "Sintered" rocker gear wear, addressed in Austin Rover service bulletins to rectify top-end noise. For K-Series models, the shared "sandwich" construction design created a universal vulnerability to head gasket failure (Part LVB101030) due to plastic dowel shifting. Cross-generation failure patterns also include gearbox-in-sump oil contamination in A-Series variants and cooling system air-locks in all 16V K-Series trims. Our reconditioned units address these historical weaknesses by utilizing uprated multi-layer steel gaskets and hardened valve seats across the entire series.
The MG Metro utilized high-output versions of Austin Rover’s most versatile engine families:
All engines in the Metro series require specific attention to the "S" vs "A" grade liners when performing block-level remanufacturing to ensure long-term compression stability.
For MG Metro owners, used engines carry high risk due to the shared age-related degradation of the K-Series cooling seals and A-Series gearbox-in-sump wear. We recommend reconditioned units for several reasons:
Quality assurance is vital as shared components, such as the distributor drive gear, fail identically across both naturally aspirated and turbocharged A-Plus variants.
Our reconditioned MG Metro engines are engineered to withstand modern traffic conditions and superior performance expectations:
All stock undergoes 4-hour dyno tests simulating real-world loads across 1.3L A-Plus and 1.4L GTi power bands, ensuring compression consistency for the entire Metro series.
We provide a 12-month warranty on all rebuilt engines. This standard coverage applies to all engine families in the MG Metro series, including Turbo and GTi variants.

When your engine fails, MG Metro engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.
1. A-Plus Engine Strip & Diagnosis
The engine is disassembled, with focus on common A-Series issues: worn rocker shafts and valve guides causing oil consumption, and crankshaft end-float. On turbo models, the turbocharger is inspected for shaft play and oil contamination.
2. Block & Head Machining for Performance
The block is cleaned, checked for cracks, and the cylinders are bored or honed. The cylinder head is refurbished with new unleaded valve seats, guides, and a 3-angle valve cut. The crankshaft is reground if necessary, and new bearings are fitted.
3. Reassembly with Upgraded Components
The engine is rebuilt with a new oil pump, timing chain, and tensioner. For performance builds, a fast-road camshaft and duplex timing gear are installed. On turbo models, all oil and water lines are replaced, and a rebuilt or new turbo is fitted.
4. Fuel & Ignition System Overhaul
The SU or HIF carburettor is fully rebuilt and tuned. For fuel-injected models, the injectors are cleaned and tested. The distributor is recurved or replaced with electronic ignition. All cooling system components (pump, thermostat) are replaced.
5. Dyno Run-In & Precise Tuning
The engine is run on a dyno with break-in oil. Valve clearances are set. Carburettor mixture and ignition timing are meticulously adjusted to achieve optimal power and smooth idle, crucial for the small-capacity engine's driveability.
6. Final Testing & Road Validation
A full compression and leak-down test confirms rebuild integrity. The engine is installed in a test vehicle or run under load to verify cooling and oil pressure. For turbo models, boost pressure and fuelling are checked to prevent detonation.
