What is Blow-By? - Diesel blow-by is a term that describes an event of lost compression into the crankcase. Blow-by occurs whenever a burnt or unburnt fuel and air mixture escape from the cylinder and past the piston rings and into the crankcase. In a perfect world, the piston would be sealed tightly in the cylinder, able to move up and down but keeping all the air and fuel and exhaust that enters or exits the cylinder during the combustion process out of the crankcase. As you'll see, this perfect world doesn't exist, but it is important to minimize the amount of blow-by in a diesel engine.
