Valve Stem Seals for Nissan engines. 6mm valve stem seals provide excellent lubrication and prevent oil from entering the combustion chamber. The seals are equipped with stiffer retaining springs for a secure fit, resulting in a durable and heat-resistant seal that is resistant to oil additives and abrasion. Properly functioning valve stem seals are crucial for the engine’s performance and longevity, as they ensure that each valve stem is sufficiently lubricated without introducing oil into the combustion chamber.
