GSC P-D Nissan VK56 Viton 6mm Valve Stem Seals - Set of 32

This set includes 32 Viton valve stem seals, specifically sized for Nissan VK56 engines with 6mm valve stems. These seals are crucial for preventing oil from entering the combustion chamber through the valve guides. When valve stem seals wear out, you'll often notice blue smoke from the exhaust, especially on startup or deceleration, and oil consumption will increase.

Viton is a high-performance fluoroelastomer known for its excellent resistance to heat, oil, and chemicals. This makes it a great material for valve stem seals, ensuring they maintain their sealing properties under the demanding conditions found in an engine's cylinder head. Installing new seals is a common part of engine rebuilding or top-end maintenance to restore proper engine operation and reduce emissions.
