Waukesha Engine Trouble shooting increase crank case pressure

The crankcase pressure in an engine like the Gas Engine Wakisha L5794 can increase due tO several reasons: 1. Blow-by gases: This is the most common reason for increased crankcase pressure. Blow-by occurs when combustion gases escape past the piston rings and enter the crankcase. Worn or damaged piston rings and cylinder walls are often the cause of excessive blow-by. 2. Clogged or malfunctioning crankcase ventilation system: The positive crankcase ventilation (PCV) valve or breather can get clogged, preventing the normal evacuation of gases from e crankcase, causing pressure to puild up. 3. Worn cylinder walls: When cylinder walls wear out, it becomes easier for combustion gases to leak into the crankcase, increasing pressure. 4. Leaking gaskets or seals: Damaged gaskets or seals, particularly in areas like the cylinder head, can allow combustion gases to escape into the crankcase. 5. Engine overheating: Excessive heat can cause increased wear on engine components, leading to more blow-by and higher crankcase pressure. 6. Oil overfilling: Overfilling the engine with oil can cause increased crankcase pressure because the excess oil can create additional resistance for the moving parts. 7. Turbocharger issues: In turbocharged engines, a damaged or leaking turbocharger seal can lead to higher crankcase pressure, as air might be forced into the crankcase.
