Anyone heard of a plugged breather cap causing oil pan leaks? I had replaced the oil pan gasket about a year ago and did all the prescribed metal straightening and gasket recommendations. After some time i noticed I was still getting some oil leaks. Realizing I had never thoroughly cleaned the breather cap I let the mesh soak in solvent and blew it out with compressed air. The leaking seems to have stopped! Is it possible that pressure was building up in the motor and forcing oil out where it shouldn't? Where does the "blow by" tube fit into this scenario?
