About This Product
This S&S breather valve seal is a specialized component designed for 1999 to 2006 Touring models and 1999 to 2005 Dyna models equipped with S&S or OEM oil pumps. In the early Twin Cam era, maintaining a proper seal in the breather system is vital for preventing oil carryover and ensuring the crankcase can breathe efficiently. S&S engineered this seal to provide a reliable interface that stands up to the pressures and temperatures found inside the cam chest. If you are servicing the oil pump or upgrading the cam plate on an early Twin Cam, replacing this seal is a smart preventative measure to keep your top end dry.
Manufacturer part number: 31-4086.
