As fuel and air get squeezed in the cylinder, some of the mixture leaks past the piston rings and carries oil from the cylinder walls with it. This mixture is known as blow-by. To prevent crankcase pressure from building up, the blow-by is then vented into the intake to be reburned. Blow-by becomes an issue with direct-injected engines when it passes the intake valves.

That carbon buildup prevents valves from closing fully and disr
