FAQ

Q: How do I know if my valve cover gasket is leaking or if it's the valve cover itself?

A: Look for oil pooling around the valve cover gasket. If the valve cover itself is cracked, you'll likely see oil seeping from the crack. A smoke test can also help pinpoint the source of the leak.

Q: Can I drive with a leaking valve cover?

A: It's not recommended. A leaking valve cover can cause oil to drip onto hot engine components, creating a fire hazard. It can also lead to engine damage if the oil level gets too low.

Q: Is it necessary to replace the valve cover bolts when replacing the valve cover?

A: It's a good idea. The valve cover bolts can stretch or become corroded over time. Replacing them ensures proper torque and sealing.

Q: What happens if I over-tighten the valve cover bolts?

A: Over-tightening the bolts can crack the valve cover, especially if it's made of plastic. Always use a torque wrench and follow the manufacturer's specifications.

Q: How often should I check my valve cover for leaks?

A: You should visually inspect your valve cover for leaks during every oil change. This will help you catch any problems early and prevent more serious damage.
