I've got an oil leak I can't seem to pin point. I've got oil film all over my filter, sending unit, oil pump, lower alternator brackets. The film collects and drips from all the previously mentioned parts Can't see it dripping or weeping while the engine runs. The leaking started when I added on board air. Doing so, required me to add the stock amc alternator brackets that help support the york unit. Has anyone had similar problems? Things I've tried already.

Replaced sending unit
Replaced oil filter
Tightned oil pump cover bolts
Retorqued oil pan bolts

I've had several AMC V-8's and never had this problem. I know their known to leak but this seems excessive.
