This will tell you the clearances & help to decide the course of action. Check the oil pump drive shaft. If i recall correctly the non turbo motors are driven by a shaft which runs off a bevel gear on the IP drive mechanism. the plug on top of the block can loosen, up the bevel gear rides up and the oil pump drive shaft goes with it, bingo the tang which should reach the oil pump no longer does. result no drive & no oil pressure. this actually happened to my buddys car , took us forever to figure that one out. Cheers Dan
