    the pan dose not hit up against exhaust and i will not need to remove also the engine mounts will not need to be or raised ... the only thing i need to do is remove the oil pump which i am doing now.

    -Disconnect battery for safety.
    -raise it up on ramps or safety stands so you can get at it.
    -drain oil obviously
    -have to disconnect exhaust at manifold and hanger at cat.conv. to allow you to lower exhaust out of the way.
    -remove starter, and bellhousing inspection plate.
    -you may have to loosen, or remove motor mount to raise engine slightly, but see what happens without.
    - remove all oil pan bolts & down it comes.

    Mike Butler Sep 27, 2009

    Shouldn't be too bad, just exhaust bolts usually can be a bit of a pain, but spray them good prior with penetrating spray (WD-40 or similar), and make sure you have an idea of where you will lift engine if needed, from above.

    I'm thinking your talking about the pick-up tube inside ?

  • Mike Butler
    Mike Butler Sep 27, 2009

    If it's the pick-up tube, try rolling pan out from one side or the other. This may be where you need to raise engine if it won't clear.

  • Mike Butler
    Mike Butler Sep 27, 2009

    The pan has to come down far enough to clear the oil pump pick-up tube.

  • Mike Butler
    Mike Butler Sep 27, 2009

    If the pan hits up against exhaust, and pan won't come down low enough to clear tube, then yes, exhaust has to be lowered.

I really can't answer this fully only because you did not list the engine size. However the most common engine is the 4.0 so Ill give you info on that.
Put the vehicle on jackstands under the chassis, use a floor jack under the front axle. disconnect the lower shock mounts, the steering damper (sideways shock on steering linkage) Lower the floor jack so the axle can hang free. Disconnect the battery (I recommend that you use a "setting saver" that plugs into the cigarette lighter to prevent radio code and channel loss) Disconnect the starter and put it aside. Remove all pan bolts. Some pans are glued on but generally you can drive a thin putty knife between the pan and block to break the bond. Remove the cover at the lower front of the transmission before lowering the pan which generally comes out to the rear and down. Remember that the oil pump pickup is inside the pan and most times you will need to maneuver around it. Like any item that uses gaskets, make sure you get every bit of gasket off pan rails and block or it will leak.
As you gave no particular reason for removing the pan, I need to note that if you have low oil pressure and are changing the pump, in 99.999% of all low pressure situations it is the bearings,not the pump that are at fault. Rod bearings can be replaced in-car, (providing that they are mildly worn, not spun or down to brass backing) but mains cannot. Rear main seal can be replaced but unless it is done very carefully it will not seal properly. If you remove any rod bearing or main caps, make sure you re-torque them afterwards I find it it is best to glue the new pan gasket either to the pan or block and let it dry before replacing pan if silicone is used, put all bolts in holes to avoid silicone from blocking them...always use a thin coat of wet silicone on face at installation to ensure a good seal. You do not need to "lean into" the bolts on retightening that will damage the new gasket. better to use gentle force and re-tighten after it is running if necessary. On four cylinder you need to disconnect the exhaust pipe at the manifold, on V6, same. As a general rule, if it's in your way, remove it!!.

Fairly easy to do. Jack the truck up and support on stands or pull on ramps and set emergency brake. Remove the dust shield from the tranny bell housing to access the rear oil pan bolts. Drain the oil from the pan and remove all the bolts from around the pan. You might have to take the engine mounts loose and jack up the engine to remove the pan completely. If so you will have to remove the fan shroud or the fan and clutch assembly to be able to get it high enough to remove the pan. Pull the pan out and do what you have to do.

    Not the clutch as in the tranny if you read the comment I posted it said the fan and clutch assembly, which is the fan clutch not tranny clutch.

Sounds like the rear main oil seal on your motor is leaking. In order for it to be replaced, the transmission has to be removed. Not an easy task for the backyard mechanic.
