Oil blow-by in a Cummins 5.9 engine is typically caused by worn piston rings, which allow combustion gases to escape into the crankcase, leading to increased pressure and oil expulsion. Other contributing factors may include excessive wear in the cylinder walls, poor maintenance, or using the wrong oil type. Additionally, a malfunctioning PCV (positive crankcase ventilation) system can exacerbate blow-by issues by failing to properly vent crankcase pressure. Regular maintenance and proper use of high-quality engine oil can help mitigate these problems.

What causes 1993 Chevrolet 5.7 to smoke oil under load Have changed intake gaskets and checked compresion.?
There are a couple possibilities: Check for "blowby", that's when exhaust gas leaks past the pistons, into the crankcase. If the engine has blowby it will be much worse when the engine is under a load. Check the vacuum lines, especially the lines from the transmission. You're looking for oil in the lines. Sometimes a broken vacuum diaphragm will allow oil to be sucked into the engine. In this case it could be that the diaphragm leaks oil only when the engine is pushing the transmission hard.
