From 1991 to 1999, the UK produced the 2.0-liter Rover 20T4G turbo engine, which was fitted to charged versions of the company’s well-known models with an index of 200, 400, 600, and 800. Because of the PG1 gearbox’s weakness, engineers had to restrict the engine’s torque.
M/T-series engines: 20T4H, 20M4F, and 20T4G.

Disadvantages of the Rover 20T4G engine
The cylinder head gasket frequently breaks here, and this turbo engine is terrified of overheating;
Camshaft and seal oil leaks are also frequent;
The unpredictable MEMS fuel injection system causes the owner numerous issues;
The turbine’s hot part frequently cracks, making it unreliable;
The timing belt must be replaced every 100,000 kilometers in accordance with the regulations; otherwise, the valves will bend.
