What is the valve clearance for the Nissan Sylphy?
1 Answers
Nissan Sylphy's intake valve clearance is 0.25mm~0.35mm, and exhaust valve clearance is 0.30mm~0.35mm. Here is more information about valve clearance: 1. Valve clearance: It refers to the gap between the end of the valve stem and the valve transmission components when the valve is fully closed. 2. Necessity of valve clearance: When the engine is running, the valve will expand due to temperature rise. If there is no gap or the gap is too small between the valve and its transmission components in the cold state, the thermal expansion of the valve and its transmission components in the hot state will inevitably cause the valve to not close tightly, resulting in air leakage during the compression and power strokes of the engine.
