Why may the engine crankcase pressure increase?

The pressure increase in the crankcase of a diesel engine indicates blow-by of the piston rings. This could be due to worn out cylinder liner or the piston rings are leaking or piston rings are broken. In that case large amount of high-pressure gas will enter into the crankcase and produce high pressure in a crankcase. Hence the substantial increase in the crankcase pressure could be an indication of a worn out cylinder liner.
