It’s normal for the pressure to be there. If you look at the top of the tank there is a vent line. In that vent line is the rollover valve. It prevents oil from coming out in the event of a roll over. Sometimes this valve will freeze and over pressurize the tank causing the seal or gasket to blow out, creating a leak. Some people are deleting this valve. You will likely need to reseal your tank.
