The "sponge" is a filter. That's supposed to be an air INLET to the crankcase; oil is not supposed to come out there.


1) Check your PCV valve. If it's stuck shut, the only way out is through the breather inlet, hence the oil in the inlet filter.


2) If the PCV is working properly, then you have excessive blowby and everyone should know what that means.
