Kibblewhite Valve Guide Seals are built to deliver long-lasting sealing performance in demanding engines. Made from 100% solid Viton®, they help control oil at the valve guide, supporting cleaner running and reliable valvetrain operation over time. Designed to meet or exceed OEM specifications, they’re a dependable choice for maintenance, rebuilds, and performance-focused engine work.
If you’re refreshing your top end or addressing oil control issues, these seals provide a precise fit for the valve stem and guide area—helping reduce unwanted oil migration while maintaining consistent valvetrain function. Important: when using Kibblewhite spring kits, Kibblewhite valve seals must be used due to spring clearances.
