The crankcase always has pressure in it. If the sump gasket is leaking, the only repair is to replace the gasket, and at same time repair the breather and replace the vent hose, but they are not the cause. Usually this is on engine that has lots f fuse and the gasket washes out over time. Here is the service manual for the series.
