What all has to be taken off to get to to the oil pan gasket


Oil Pan REMOVAL & INSTALLATION
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Drain the crankcase.
  3. Remove or disconnect the following:
    • Negative battery cable
    • Oil level indicator harness connector, if equipped
    • Exhaust Y-pipe, if needed
    • Transaxle assembly from the vehicle.
    • Oil pan bolts and the oil pan
    To install: NOTE: The oil pan gasket is reusable unless it is damaged. Do not remove the gasket from the oil pan groove unless gasket replacement is required.
  4. Thoroughly clean the inside of the oil pan and the cylinder block contact surface. If the oil pan gasket is being reused, be careful not to damage it. Do not expose the gasket to cleaning solvents.
  5. If a new gasket is being installed, start the gasket into the oil pan groove and work the gasket into the groove in both directions. Once the gasket is exposed to oil, it will expand and no longer stay in the groove without wrinkles. If this condition exists, replace the gasket.
  6. Install or connect the following:
    • Oil pan. Torque the bolts, in sequence, to 89 inch lbs. (10 Nm).
    • Oil level indicator connector, if removed
    • Transaxle assembly, if removed
    • Y-pipe, if removed
    • Flywheel cover, if removed
    • Oil pan drain plug. Torque it to 15 ft. lbs. (20 Nm).
    • Negative battery cable
  7. Refill the crankcase.
  8. Run the engine and check for leaks. Fig. 1: Oil pan bolt torque sequence 7922vg08.gif

I want to know how change my oil pan gasket.


The oil pan gasket is a complex task. Due to the design of the Northstar engine,ie the exhaust crossunder exhaust pipe either the engine has to be removed from the car or remove the transmission.... The oil pan is a two piece assembly. Upper and lower. Yhank you

How do i remove the oil pan


REMOVAL & INSTALLATION - Oil Pan

CAUTION The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used. (except 2.5 Premier engine)

Fig. Fig. 7: Apply sealant to the ends of the new oil pan end seals at the junction of the cylinder block pan rail gasket-1988-95 2.2L and 2.5L except Premier engines

db01a06.jpg

Fig. 8: Clean the gasket mating surface of the oil pan of all old gasket material, dirt, grease or other grime-2.6L engine
  1. Apply the parking brake, block the rear wheels, then raise and safely support the front of the vehicle on jackstands.
  2. Drain the engine oil. This would also be a good time to change the oil filter.
  3. Remove the engine-to-transaxle struts, if so equipped. These struts prohibit access to the oil pan mounting bolts.
  4. Remove the torque converter or clutch inspection cover.
  5. Support the oil pan and remove the mounting bolts.
  6. Lower the pan and remove the old gasket, if so equipped.
To install:
  1. Clean all gasket surfaces thoroughly.
  2. For 2.6L engines, position a new gasket on the oil pan using a sealer to hold it in place.
1981-87 2.2 and 2.5 Liter engine uses a liquid form-in-place type gasket. Chrysler Part Number 4205918, or equivalent RTV gasket material must be used.
  1. For 1981-87 2.2 and 2.5L engines, install new end seals and apply the form-in-place gasket sealant. The RTV gasket material should be applied in a continuous bead approximately 1 / 8 in. (3mm) in diameter. All mounting holes must be circled. Uncured RTV may be removed with a rag. The oil pan should be tightened in place while the RTV is still wet to the touch (within 10 minutes). The usage of a locating dowel is recommended during assembly to prevent smearing of the material off location. Make sure to apply sealer where the end seals meet the block.
1988-95 2.2L and 2.5L engines utilize end seals and side gaskets, not liquid gasket as with 1981-87 models.
  1. On 1988-95 2.2L and 2.5L engines, install new end seals and side gaskets. Apply RTV sealant to the parting lines between the end and side seals on these engines. If necessary, use a little grease or RTV sealant to hold the side seals in place.
  2. Tighten the pan bolts in a crisscross fashion, starting from the center of the oil pan and working toward the ends, to the following torque values:
    2.6L engine-53-61 inch lbs. (5.9-6.8 Nm) 1981-87 2.2L and 2.5L engines-16 ft. lbs. (22 Nm) 1988-95 2.2L and 2.5L engines-M8 bolts, 16 ft. lbs. (22 Nm); M6 bolt, 105 inch lbs. (12 Nm)
  3. Allow the oil pan to sit for 15 minutes to ensure that the RTV sealant has completely set.
  4. Install the oil drain plug and a new oil filter, if equipped, then lower the vehicle.
  5. Refill the engine with oil
  6. Start the engine and check for oil leaks.

Hope helps (remember rated this).

How do I change the oil gasket??


Are you talking about the oil pan gasket, valve train cover gasket? Id so on either one you must remove the old gasket an replace it. You can try tightening the bolts some to see if that stops the leak, but if not, the gasket should be replaced.

Hi, I have a 1988 plymouth voyager and it has a very bad leak in the oil pan, I wanted to know if it's dificult to change the gasket on this type of vehicle. Thanks


Hi, on your 1988 voyager it is not a difficult job to reseal the oil pan, just make sure all parts are clean before reassembly.
