The one I have in my parts bin is a Purolator steel canister and is exactly the same as the one on my tractor which has a 4-cylinder Continental flathead F400 series engine. The Purolator is stamped INLET at the bottom center (oil would enter the canister's center pipe here)and flow into the inside pipe. There is a single, very tiny hole in the side of this pipe, probably no more than 1/16" diameter. There is no air or oil escape anywhere else on this pipe tower, it is closed off and threaded at the top (for attatching the canister lid). The other opening is stamped OUTLET and it is located on the side of the canister, not too far from the top edge. So on this one anyways, oil obviously is filtered from the inside of the filter to the outside. Maybe others are different. There is no pressure relief set up here since it is part of a bypass oil filtration system. A plugged filter doesn't mess up anything other than the oil stops being filtered but the engine still gets a full oil supply. I couldn't see this system working the other way, that hole in the inner stem would be too small to pass any signifigant amount of oil back to the engine because of the pressure drop on the way back. I think I have mine done right for this particular engine, not all engines, but this engine with a bypass system of filtering.
