First drain the oil and drop the pan and inspect the rod bearings, if they're smoked you're gonna have to do that too. Then after that it's pretty easy. Takes about 5 hours I would say. The oil pump bolts on the front of the engine and is driven directly off the crank shaft. Basically the repair entails removing the right front inner fender and the oil pan. Then take off the serpentine pulley, balancer and a tensioner. Then all you do is remove the old pump and install a new one. Make sure to grease your new oil seals and clean all of the mating surfaces well.
