- Manufactured in the USA
- High Temperature Silicone
- Hi-Tech Fluoroelastomer (FKM) Materials
This newly engineered solution is part of our complete line of high quality valve cover gaskets. Sinister Diesels valve cover gaskets are constructed of premium synthetic rubber compounds such as high temperature silicone and hi-tech fluoroelastomer materials. Our gaskets are designed to withstand the high temperatures and pressures of the engine, providing a tight seal that prevents oil leaks and other issues.
Comparing our product with off-shore offerings, it becomes clear that their product is being made using inferior rubber compounds consisting of low-cost fillers which result in inconsistent sealing and poor high-temperature resistance. During injector replacement, the valve cover must be removed on most applications, this is a perfect time to replace the valve cover gasket to ensure a professional, leak-free repair.
