What are the common issues to look out for in a BMW M3 engine?

I have recently purchased a used BMW M3 and I want to make sure I am aware of any potential issues with the engine. Can you provide any insight on common engine issues and how to prevent them?

It is always a good idea to do a thorough inspection of the engine before purchasing a used car. Some common issues in BMW M3 engines include oil leaks, high oil consumption, and failed VANOS systems. To prevent these issues, make sure to regularly check for oil leaks and maintain proper levels of oil. It's also important to have the VANOS system serviced at recommended intervals.

Another issue to look out for is the cooling system. The plastic parts of the cooling system are prone to cracking, leading to potential overheating and engine damage. It's recommended to replace these plastic parts with more durable metal alternatives. Regularly checking and replacing the coolant is also crucial in preventing issues.
