You need to remove the transmission inspection cover under the torque convertor and also the bolts the hold the motor mounts together so you can jack the front of the engine up about 3 inches so the oil pan will slide out. You also need to take off the starter. Hope this helps.

How to remove oil pan on 94 jeep V8

I am pretty sure that you either have to have the transmission out or pull the motor mount bolts and jack the engine up to make the clearance for the pan to come out.

How to replace oil pan

5.2 liter V8 engine?

Remove the four front skid-plate bolts holding the front skid plate, using a ratchet and socket. Remove the skid plate.

Pull the plastic splash shield away from the vehicle, loosening the retaining clips. Remove the splash shield.

  • Place an oil drain container under the oil pan. Loosen the drain fitting with a wrench until oil drains from the pan. When oil is done draining, tighten the drain fitting.

  • Disconnect the electrical connections running to the starter motor. Remove the starter motor mounting bolts with a ratchet and socket, then remove the starter motor.
  • Remove the oxygen sensor socket from the exhaust pipe, using a wrench.
  • Remove the exhaust manifold bolts where the exhaust meets the manifold on both sides, using a ratchet and socket
  • Place an jack under the transmission to support it. Remove the pressure on the transmission crossmember.

  • Remove the bolts that hold the transmission crossmember in place, using a ratchet and socket. Then remove the crossmember. Place a jack stand under the transmission to keep the transmission from falling off the jack if hit. Once removed, the exhaust will hang down, allowing enough room to remove the oil pan.
  • Disconnect the oil level sensor and the nut retaining the transmission cooling lines, using a wrench.
  • Remove the oil pan bolts with a ratchet and socket, then remove the oil pan and gasket.
  • Clean the mounting surfaces of the new oil pan and engine block. Make sure what ever you use to clean the surfaces dosn't gouge the metal.
  • Place a coat of RTV (gasket) sealer on the engine block where the pan will meet the rear main cap.
  • Place the new gasket on the pan and push the new oil pan into place. Finger tighten the oil pan mounting bolts to hold it in place. Tighten the bolts with a torque wrench to 18 ft-lbs. DO NOT OVER TIGHTEN THE BOLTS! Doing so will cause the gasket to deform and create leaks!

  • Connect the oil level sensor and the nut retaining the transmission cooling lines, using a wrench.
  • Place the exhaust back into position and replace the transmission crossmember bolts and crossmember with a ratchet and socket.
  • Remove the jack supporting the transmission.
  • Connect the exhaust back to both sides of the manifold, tightening the bolts with a torque wrench to 20 ft-lbs.
  • Attach the oxygen sensor socket to the exhaust pipe with a wrench.

  • Replace the starter motor by installing the starter motor mounting bolts with a ratchet and socket. Connect the electrical connections to the starter motor that were disconnected during removal.
  • Push the retaining clips on the plastic splash shield into the appropriate retaining clip holes.
  • Replace the front skid plate by replacing the four front skid plate bolts with a ratchet and socket.
  • Fill the engine with 5 quarts of oil. Make sure to check the level on the dipstick to find the exact level when filling.

    Removal procedure of oil pan for a 1997 chevy

    To remove the engine oil pan either the engine has to be lifted all the way off of the motor mounts and the oil pan should just clear the flex-plate and transmission, or the front axle dropped down out of the way, or the transmission and flex-plate will have to be removed.

    Usually if the engine can be lifted enough to fit a piece of 2x4 wood between the motor mounts and the frame then the oil pan will usually just have enough clearance to be removed from the rear and the oil pan should just clear the transmission and the flex-plate. Also, be sure to check that the fan blade does not damage the fan shroud when lifting the engine.

    Let me know if you require any further assistance.

    Trying to drop the oil pan out of my 1994 Ford F-150 (4.9L) to replace the gasket. Ive taken out the motor mounts and jacked the engine almost high enough to get the oil pan out and I am wondering if i...

    done this on several i-6 f-150s. slide back or remove transmission, remove motor mount bolts from frame(not motor), jack motor up as far as possible without damaging egr valve or wiper motor when they hit, shim under motor mounts so that when you drop the jack the motor does not come back down any(the motor is well balanced on the mounts, it will not fall out of the truck like a v8 will), then remove the oil pan. you May have to remove the pickup tube(usually not), and you May have to rotate the crankshaft so that the lobes clear the oil pan. this is a common problem with these trucks due to the size of the oil pan(Huge), and the minimum pan to crossmember clearance
