I have my oil pan off, my jeep has 160K miles on it, should I go ahead and replace the oil pump? I replaced the rear main seal already. Does anyone have any experience with how many miles it takes to kill an oil pump on the 4.0L.. Also the Block is a 1996 and heads are 1988, is the 96 block oil pump the same Part Number as the 88.
