What is the purpose of a valve stem seal?

Valve stem seals are designed to prevent engine oil from leaking down the valve stem and into the combustion chamber. This helps maintain proper oil levels, reduce smoke, and ensure efficient engine operation.

Are these seals for intake or exhaust valves?

These specific Cometic valve stem seals are designed for the exhaust valves on the 5.9L ISB Common Rail engine. They are identified by their green color.

What do the dimensions of the valve stem seal mean?

The dimensions (.265in. x .500in. x .635in. x 1.126in.) refer to the inner diameter, outer diameter, height, and overall width of the seal, ensuring it fits correctly onto the valve stem and into the cylinder head.

About this part

Product Details

When you're rebuilding the top end of your 2003-2008 Dodge Ram 2500 or 2003-2007 Ram 3500 with the 5.9L ISB Common Rail engine, replacing the valve stem seals is a critical step. This Cometic Green Metal Jacket Valve Stem Seal is designed specifically for the exhaust valves, helping to keep oil from leaking past the valve guide and into the combustion chamber. This is important for maintaining proper engine compression and preventing excessive smoke.

These seals measure .265 inches on the inside diameter, .500 inches on the outside diameter, .635 inches in height, and 1.126 inches in overall width. The metal jacket construction offers a durable seal, and the green color helps identify them as exhaust seals. Replacing these seals ensures a cleaner burn and can help restore lost engine performance.
