Disadvantages of the Rover 18K4K engine
This engine’s primary issue is its extreme fear of overheating;
As a result, it frequently leads the head in addition to breaking through the cylinder head gasket;
Additionally, remember to replace the costly, long head bolts each time you remove it;
The valves always bend when the timing belt breaks, which is intended to last 100,000 kilometers;
Ignition coils and short-lived supports are two more of the motor’s flaws.
