Just to chime back in i fixed the problem. Im not sure which one was the culprit, but i replaced the oil filter with a K&N filter and took the plunger out and didnt find any scoring or anything. Put it back in and Poof magically oil pressure reappears. Its back to showing 50-60 at startup. . I think it was the LPS syndrome. Little Pieces of S$#&. Thanks everyone for the replies.
