Finding coolant mixed with engine oil in a machine running a Weichai WP12 Engine is a severe failure, often indicated by milky oil (sludge) and pressure loss. The most common causes are a failed Cylinder Head Gasket (part of overhaul gasket kits), or a crack in the Cylinder Head or Cylinder Block.
**Solution:** The engine must be immediately stopped and drained. The Cylinder Head must be removed and pressure-tested for cracks. If the head or block is cracked, replacement is necessary. If only the gasket is failed, a full engine strip-down and rebuild is needed, utilizing a complete overhaul gasket kit and ensuring all components, including the piston and cylinder liner, are clean and within specification to prevent immediate re-failure and ensure reliable heavy machinery overhaul.
