EDIT-> Added pic of inside the front cover. The 3 areas circled did not have rubber seals, just packed with silicone sealer. Motor has never been apart so I know this is factory. Is this normal, just to use goop in these areas?. It looks like the 7.3 is basically glued together in some areas.
Cleaned up the front cover and noticed some wear/scoring between the input/out ports (circled RED) and wondering if it will affect oil pressure. I wouldn't think this is NOT a contact surface for the pump rotor since it's aluminum but there is some wear from something.
I can facet off .003"" and then take off .003"from the pump housing mounting surface but don't know if that's a waste of time or side clearance is even an important tolerance.
Oil pump surface looks ok to me, mine was worse looking
New Melling pump flows more than stock so not an issue for me.
I would think a gasket but if facory did it, they used TA 31 and its not just any rtv, more like RTV glue that cures in minutes
Thanks man, I'm going with the Mellings also. Those channels in those areas milled in the cover are thinner than the others maybe because thew wall thickness is thinner and a rubber seal wouldn't do it. I'll just fill it up with than magic Ford grey goop in the $40 mini caulk tube.
