What is the valve clearance adjustment for Yuchai 24-valve engines?

[LeRemington]

Intake valve 0.3mm, exhaust valve 0.35mm. 1. Explanation: The exhaust valve clearance should be larger than the intake valve clearance because the exhaust valve is exposed to much higher temperatures than the intake valve due to exhaust gases, hence requiring approximately 0.05mm greater clearance. 2. Precautions: Improper valve clearance (either too large or too small) in Yuchai generators will cause decreased diesel engine power and reduced fuel efficiency. During diesel engine operation, valve clearance must be regularly inspected and adjusted. For multi-cylinder diesel engines, adjustments should be made sequentially according to the firing order and valve arrangement.
