Chevrolet Cruze severe engine oil spills

         Mileage of about 14,000 km, 1.8L engine configuration Chevrolet Cruze sedan. Reflects the owner: a serious car engine oil spills, engine compartment everywhere greasy. 
         Troubleshooting: Check the engine valve chamber cover was found around the obvious signs of oil spills, indicating failure of the valve chamber cover mat oil spills, and in the replacement of the valve chamberrenault can clip diagnostic interface cover pad and clean up traces of oil found during the injector plugs, ignition coil plugs, oxygen sensor plug also has oil, that is a long oil spills valve chamber cover pad, so do not care about the oil penetrated inside the plug, washing with detergent and dry with compressed air after reassembly. 
         However, after traveling more than 2,000 kilometers, the owner found the engine compartment has shown a significant oil spills dirt phenomenon, after examination found no oil spills around the valve chamber cover again, but the engine wiring harness and the last treated injection plugs, ignition coil plug, plug in the oxygen sensor, again appeared oil, engine harness those where oil is escaping from it? 
         To find out the reasons, expanding the scope of the inspection, it was found relatively far away from the valve chamber cover engine control module plugs are also oil, which excludes oil spills flow valve chamber cover pad harness and plug may, in examination rear of engine oil pressure sensor is found, plug all the oil, not the sensor internal oil spills is suspected, then start the engine observation, that is indeed a constant outward from the sensor connector terminals permeability, which is the cause of the failure analysis pressure oil through the engine lubrication system, oil pressuredigimaster 3 update sensor within the internal infiltration through the engine wiring harness, and the role of capillarity of infiltration along the various electrical components of the engine wiring harness connector, the formation of the oil spills dirty phenomenon. Troubleshooting: Troubleshooting After replacing the damaged oil pressure sensor. 

         Fault Summary: When checking the engine oil spills failure, in addition to checking seals and gaskets around, also check the oil channel plug and oil pressure sensor for leaks; if you find the harness and electrical plugs appear antifreeze, then it To check the internal temperature sensor is not leaking.
