What engine codes fit MG Metro models-

MG Metro models use A-Series 998cc (early L variants) or A-Plus 12H 1275cc (most 1300 and trim variants). Turbo models use the A-Plus Turbo code with Garrett T3 turbocharger and mechanical wastegate.

Check your MG Metro engine code compatibility instantly

What causes MG Metro head gasket failure-

Thermal cycling degrades the standard composite head gasket on A-Series/A-Plus engines. Classic cooling system layout exacerbates hot spots, especially in modern stop-start traffic without upgrades.

  • Standard gasket material degrades with repeated heat cycles
  • Cooling system inefficiency creates localised hot spots
  • MLS (multi-layer steel) gasket upgrade recommended during rebuild
  • Overheating damage may require full engine replacement

  • Specialist rebuilds preserve original 93PS output and boost characteristics
