FAQ

1. How do I know if these valve seats will fit my engine?
These valve seats are specifically designed for the Nissan Da640 engine. Please check your engine model number on the engine block data plate. The OEM part numbers 9-12552-150-0 (intake) and 9-12552-150-1 (exhaust) must match your original parts for a direct fit.

2. Do I need to machine the cylinder head to install these seats?
Yes, installation typically requires a machine shop. The old valve seats must be carefully removed, and the cylinder head counterbores should be machined to the correct depth and diameter. These seats are then pressed or shrunk into place. We recommend having a professional engine rebuilder perform this task.

3. What is the difference between the intake and exhaust valve seats?
The intake valve seat (9-12552-150-0) and exhaust valve seat (9-12552-150-1) are made from different materials or have different heat treatments. The exhaust seat must withstand higher temperatures from hot exhaust gases, while the intake seat is designed for cooler intake air. Using the correct seat for each position is critical for engine longevity.
