Remove oil pan and pump is bolted to back main bearing cap. But this is most likely not the problem. This engine is known for cam bearings spinning out of the block and cam shaft breaking inbetween #3 and 4 cam journals, oil pump is driven off the end of camshaft, engine runs very rough and makes all kinds of noise when this happens, cure is a new engine. to check for broken cam shaft removed front valve cover, have some one start or crank the engine, the 2 rocker arms on the drivers side will not move at all, most likely there will be silver metal dust laying in the low spots of the head where oil puddles up.
