FAQ

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

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

Q: Is it easy to replace the engine cover myself?
A: It's generally a straightforward repair, but you'll need basic tools and some mechanical knowledge. If you're not comfortable, a professional can do it.

Q: Will a new engine cover improve my car's performance?
A: The engine cover primarily protects the engine. Replacing a damaged cover won't necessarily improve performance, but it will prevent further damage.

Q: What should I do if I still have oil leaks after replacing the engine cover?
A: Double-check the installation and make sure the gasket is properly seated. If the leaks persist, there may be other sources, such as the valve cover gasket or oil filter housing gasket.
