Good To Know

Q: Does this gasket require sealant during installation? A: Most valve cover gaskets install dry unless the service manual specifies a sealant at certain points. Always follow the factory torque sequence for best results.

Q: How often should a valve cover gasket be replaced? A: Replace it whenever the valve cover is removed or when oil seepage appears around the cover. A fresh gasket helps prevent leaks and keeps the engine bay clean.
