I just recently installed my 6.5l and came across another situation that made me go hummm! When I got the engine back from the shop the oil ports had been plugged. Well there just happens to be three in that general area. ( just to the back side of the oil filter). Just to be on the safe side, which two are the correct ones? The are in a triangle shape, front, back and one in the middle but higher up on the block. I chose the front and the back, just because the lines seem to fit there good. Did I pick correctly?

did it work?
