What is the main purpose of valve stem seals?

Valve stem seals are designed to prevent engine oil from entering the combustion chamber through the valve guides. Worn seals can lead to increased oil consumption and blue smoke from the exhaust.

What material are these valve stem seals made from?

These valve stem seals are made from Viton, a material chosen for its excellent resistance to high temperatures and engine oils, ensuring durability in the engine's cylinder head.

How many seals are included in this pack?

This pack contains 16 valve stem seals. This quantity is typically sufficient for most 4-cylinder engines, or for specific applications on engines with more cylinders.

About this part

Product Details

This is a 16-pack of Cometic Gasket Viton valve stem seals. These seals are crucial for keeping oil from getting past your valve guides and into your engine's combustion chambers. When valve stem seals start to wear out, you'll often notice blue smoke coming from your exhaust, especially on startup or when decelerating. Replacing them is a key part of rebuilding or refreshing an engine's top end.

The seals are made from Viton, a material known for its resistance to heat and oil, which means they'll hold up well in the demanding environment of the cylinder head. This particular set features a positive seal with a ring, designed to provide a secure fit and effective sealing. The dimensions are .162 inches for the inner diameter, .288 inches for the outer diameter, and the overall height is .333 inches with a .219-inch seal diameter. This pack includes 16 seals, enough for most 4-cylinder engines or for specific applications on larger engines.
