      you have to raise the engine up some by removing eng. mounts, starter and front y exhaust pipe. take oil pan down and remove the oil pump. it help a lot if you drop the front differential since it is very thight to put it back carefully so the seal or gasket won't fall in the oil pan and you may not see it
