I have a huge oil leak that is coming from right around the oil pressure switch, i replaced that and the problem still exists, it appears to be coming out between a gasket and the pressure switch. anyone know where it could be leaking from???

There is a seal behind that pulley, pressure wash all the oil that has leaked out and run it and see if that seal is the source of the leak or it is coming from somewhere else. You need a completely clean engine to find an oil leak
There is no need to add oil to an ac compressor unless you have had a massive leak. new compressors come with the right amount of oil. The compressor oil circulates with the gas and by the time the gas pressure drops from a leak then the amount of oil leaked out is just a few drops. Excessive oil in the system stops the TX valve from working and causes problems . If still in doubt then talk to an accredited ac specialist
The easiest thing to do is get a new one, remove the old wone, and install the new one.
The oil is supposed to be kept separate from the electrical part, but sometimes they spring an internal leak. Replacing is easier than trying to get really specific about just where the oil is coming from. And once you do get specific, you almost always reach the same finding: a new unit is needed.
Oil pressure sensors seem to be the least reliable of them all; I'd replace it first and if it is still showing low pressure, have a shop check with a real pressure gauge.
It shouldn't cost much and won't take long to do.
If it then shows low pressure, the oil pump may be worn or the pickup impeded with gunk (bad maintenance.)
