What is the most common issue with the BMW M1 engine?

I have noticed that my BMW M1 engine has been struggling lately. What is the most common issue that I should look out for and how can I prevent it?

The most common issue with the BMW M1 engine is overheating. This can be caused by a lack of coolant or a malfunctioning cooling system. To prevent this issue, make sure to regularly check and top off your coolant levels and have your cooling system inspected by a mechanic.

Another common issue is oil leaks, which can be caused by worn gaskets or seals. It is important to address any oil leaks immediately to prevent damage to the engine. Regularly scheduled maintenance and inspections can help catch and fix any potential issues before they become bigger problems.

One thing to keep an eye on is the timing chain. If it becomes loose or worn, it can cause major engine damage. It is recommended to replace the timing chain before reaching 100,000 miles. Otherwise, it can lead to costly repairs.
