Disadvantages of the Rover 20K4N engine
- Structurally, this is a motor with wet liners and they can sag when overheated;
- Sagging liners leads to a mixture of oil with antifreeze and a major overhaul awaits you;
- Another well-known engine problem is the ingress of lubricant into the throttle assembly;
- If the three-belt timing belt is incorrectly replaced, it is easy to damage the camshafts here;
- Weaknesses also include a thermostat, pump, cooling fan.
