Why is oil blowing out of the breather hole?
For instance, in a piston compressor, the movement of the pistons and the clearance between the piston rings and cylinders allows some of the pressure created in the cylinders to pass into the crankcase. Therefore, with the crankcase being a sealed chamber, a breather is needed to relieve the pressure to ensure this oil doesn’t cause a blow out.
Why do I need to use a breather on a pump?

Why is fluid coming out of the filler or vent cap of my?
Especially a problem when a tank has been topped off while the cylinder (A.K.A. actuator) is left extended, which makes it full of oil, so that once the cylinder comes back down to the completely retracted position, the excess oil takes the path of least resistance which is most likely the filler vent cap on the oil reservoir.
