What is the purpose of a valve stem seal?

Valve stem seals are crucial for preventing oil from leaking down the valve stem and into the combustion chamber. This helps reduce oil consumption and blue smoke, especially noticeable on startup.

What do the dimensions of these seals mean?

The dimensions refer to the specific fitment points. The .265in is the inner diameter that fits the valve stem, .500in is the outer diameter that fits the valve guide, and the .635in is the overall height, with 1.126in being the spring height.

Why are these called 'Metal Jacket' seals?

The 'Metal Jacket' refers to a metal casing integrated into the seal's construction. This design helps provide a more robust and stable seal around the valve stem, contributing to its durability and effectiveness.
