Installation Notes and Tips

Confirm valve stem diameter, seal height, and guide dimensions before installation. This seal is listed for 8 mm valve stems and should be matched to the engine specification, not just the vehicle model. Clean the valve guide area thoroughly, inspect the stem and guide for wear, and install the seal squarely to avoid damage to the sealing lip.

Fitment is listed for multiple positions, including N/A and Exhaust on select applications. Verify the exact cylinder head and valve location before ordering, especially on Nissan Pathfinder, Nissan Frontier, and Nissan 300ZX service jobs.
