lost oil pressure

We are trying not too take the front of the engine apart. This is a 69 Charger, the pain of pulling all that stuff back out---custom denso, costum air, pos p/s , 3 row rad, and 2 old men bending over a long nose charger, lol.

crapola, but it ain't right. I already measured, to replace the cam; rad, a/c condenser, even a body strut cut. Just looking for a quick fix, but we know that ain't happening. Poop. Over a year, rotessorie and all; he is so bummed out.
