Valve stem seals, which differ from other seals in the engine, are crucial for lubrication. With the use of valve stem seals, the valve stem may be kept lubricated as it passes through the valve guide. It's crucial to closely regulate the flow of oil beyond the valve stem seal.

By allowing a certain amount of oil to flow within the valve stem as it moves, valve stem seals regulate the amount of lubrication and oil used in an engine. In order to ensure proper lubrication, a controlled amount of oil is essential. In the absence of oil, numerous components may corrode as they rub against one another.
