Disadvantages of the Rover 20T4H engine
- This is a very reliable motor structurally and its main problem is poor workmanship.
- In second place there are malfunctions in the capricious MEMS fuel injection system.
- The timing belt is designed for approximately 100,000 km of run, and when it breaks, the valves bend.
- Often there are oil leaks from under the valve covers and camshaft seals.
