    Default Oil Pump ?

    Hey guys, Do I need to pull the motor to replace oil pump on my 2000 Durango with a 318, not looking forward to it if need to. Comming home from the loonie run, I lost all oil presure the last mile home. Nursed it home and changed oil/filter, now the bottom end rattles a tad, and the oil presure goes up/down contantly.

    No need to pull engine.
    You can figure on about 1 hour. Drain oil. While it is draining, remove the passenger side auxillary support strut that goes from the motor mount to the transmission. Put the plug back in the pan, and proceed to remove the oil pan bolts (14 maybe?). Slide the oil pan out. There will be three bolts that hold the pump in place. Remove two. Then slide an oil catch pan directly underneath the pump, remove the last bolt, and place the pump into the pan.
    Next, unthread the pick-up tube from the old pump and clean it thoroughly. Thread the clean pick-up tube into the new oil-pump. Prime the pump by submersing the pick-up in oil and turning the drive with a 5/16" (I think) allen wrench. Install the new pump by first inserting the drive shaft into the pump, and the turning the pump to align the bolt holes.
    The oil pan gasket is reusable, though you may choose to install a new one. Reinstall the oil pan, making sure that the gasket tabs where the pan meets the transmission are inserted into their holes (you will have no doubt as to what this means when you do it). Get all the bolts snug and then torque them outwards from the center in an orderly fashion, i.e center two- left and right, then the two-left and right-towards the front of the engine, then the two-left and right- toward the transmission, and so on spanning outward. Reinstall the engine to transmission support strut. You are done, unless you want to go over an hour....
    As an added precaution you can remove the spark plugs, unplug the injectors, and crank the motor for 5-10 seconds. This will drive the air between the primed pump and the channel that it pumps into up into the valve covers.
    A trick to keeping the gasket in place during install. Tie the corners in place with thread (through the bolt holes). After getting all the other bolts started ... cut the threads and pull them out ... install corner bolts.
    Inspect crank to see if you have any bad bearings.

    Remove the starter as well which is also a pain to do.

    Rattle is bad. Hope you didn't do more damage to the motor.

    Rattles just a tad on warm up, then goes away, oil presure is showing on the gauge, but not even close to where it use to run in the past.
