What is the main purpose of a valve stem oil seal?

Valve stem oil seals are designed to prevent engine oil from leaking down the valve stem and into the combustion chamber. This helps reduce oil consumption and keeps the combustion process cleaner.

What does the 'SEALS-3/8 STEM' designation mean?

This designation indicates that these specific valve stem oil seals are intended for use with valve stems that have a 3/8 inch diameter. It's important to match the seal size to your valve stem size for a proper fit.

Are these seals sold individually or as a set?

The product listing is for a set of 16 valve stem oil seals, which is typically enough for a standard 8-cylinder engine (4 intake and 4 exhaust valves per cylinder).

About this part

Product Details

If you're rebuilding the top end of your engine, replacing the valve stem oil seals is a crucial step. These Manley seals are designed to fit 3/8 inch valve stems, effectively preventing oil from leaking down the valve guides and into the combustion chamber. Keeping oil out of the combustion area helps maintain proper engine performance and reduces oil consumption.

Manley Performance is known for making well-built engine components, and these seals are no exception. They are made to handle the heat and pressure found in an engine's cylinder head. Proper installation ensures a tight seal, which is key to preventing blue smoke on startup and maintaining a clean burn.
