Detailed Description
Mahle SS45944 is an engine valve stem oil seal set designed to maintain proper sealing at the valve stem in intake and exhaust locations. The fluoroelastomer construction is selected for demanding engine environments where exposure to heat and oil is constant. With a 0.202-inch inside diameter and 0.59-inch outside diameter, this seal set is built around precise fitment dimensions for the listed Ford, Lincoln, and Mercury vehicles. This part cross-references FEL-PRO SS 72921 and Ford 3L3Z-6571-DA for the same application.

What It Helps Address
- Oil leakage past worn valve stem seals
- Blue exhaust smoke caused by oil entering the combustion chamber
- Oil consumption related to deteriorated stem sealing
- Rough idle or fouled spark plugs from oil contamination
- Loss of sealing performance in intake and exhaust valve areas
Installation Notes and Tips
Verify engine code, valve train configuration, and seal dimensions before installation. Match the seal to the intake and exhaust valve positions listed for your application, and inspect valve stems and guides for wear that could affect sealing performance. Clean mating surfaces thoroughly and follow the service procedure for the specific Ford, Lincoln, or Mercury engine.
Quality Assurance
Mahle gaskets and sealing components are used by OEMs and technicians worldwide, and SS45944 follows that OE-focused approach with application-specific dimensions and fluoroelastomer material selection.
