FAQ
Q1: Will these valve seats fit my Nissan TD42 engine without machining? Yes, these seats are precision-ground to OEM specifications and are designed as a direct replacement. However, we recommend a professional cylinder head shop perform a final seat cut (0.5mm max) to ensure perfect concentricity with the valve guide centerline after installation.
Q2: What is the recommended installation procedure to avoid valve seat drop? For optimal retention, use a shrink-fit method: chill the cylinder head to -10°C (14°F) and heat the valve seats to 150°C (302°F) prior to pressing. Ensure the counterbore in the head is clean and free of carbon deposits. After installation, allow the head to cool naturally to room temperature before valve grinding.
Q3: How do I identify intake vs. exhaust valve seats in this set? The intake seats (part number 13214-97000H) have an outer diameter of 44.0 mm, while the exhaust seats (13215-96005H) are 38.0 mm. They are packaged separately with clear labeling. The exhaust seats use a slightly harder RF8 grade to handle higher combustion temperatures.
