612630040181 Valve Guide for Weichai WD615/WP10

612630040181 Valve Guide – For Weichai WP12/WP13 Engines 1. Product Overview If you maintain SHACMAN X6000, X3000, or HOWO trucks with Weichai WP12 or WP13 engines, you know this: worn valve guides cause blue smoke on cold start, unexplained oil consumption, and idle instability. The valve guide is a precision bushing pressed into the cylinder head. It keeps the valve stem moving straight and maintains correct stem-to-guide clearance. When the guide wears, the valve wobbles on its seat — causing poor sealing, oil slipping into the combustion chamber, and compression loss.
