Well first of all the reason I "assumed" these motors were a Ford is because Ford Motor Company owned them from 2000-2008 so I just assumed that it was a Ford based 4.6 motor. I got the gasket done yesterday evening. Turned out that the oil pan was warped. So I replaced gasket and oil pan and resolved oil problem.

 

Do wanna give a big "Thanks" tho to everyone who gave there advice and help. It was much appreciated!
