FAQ

Q: How do I know if my engine cover is cracked?
A: Look for visible cracks, especially around the edges and mounting points. You might also notice oil leaks or hear rattling noises.

Q: Can I drive with a cracked engine cover?
A: It's not recommended. A cracked engine cover can allow oil leaks, debris to enter the engine, and cause other problems.

Q: Will a new engine cover improve my car's performance?
A: A new engine cover primarily prevents oil leaks and protects the engine. If your old cover was damaged and causing problems, replacing it will restore proper function.

Q: Do I need to replace the gasket when I replace the engine cover?
A: Yes, it's highly recommended. The old gasket may be worn or damaged, and replacing it ensures a proper seal.
