    2.4 rear main seal is replaced by removing transmission and the flywheel. VERY easy trans removal on the 2.4 engine.

    Once all is removed, the rear main is looking at you. Two choices: remove the seal and install using the factory instalation tool or remove the seal retainer (fairly easy) and remove old seal and install new seal flush with retainer using a flat pice of wood large enough to cover the seal for its final tapping into place. Insure you prelube the inner lip of seal before installation to prevent burn.

    OEM seal is what you want. Accept no subsitutes. About $18 at dealer. It is a one piece, metal clad lip seal.

    Make sure it's the rear main seal that is leaking. This engine has a big problem with head gaskets leaking from the right rear corner of the engine(the corner of the engine closest to the driver) also the oil pressure switch is mounted on the right rear of engine and it will also look like a rear main seal leak. Rec you use oil dye and then have it checked with a black light to see where exactly it is leaking before you start taking major components off. HTH Greasemonkey :)

    Greasemonkey,

    The MLS head gasket updates were installed on Model Year 1999 2.4's. Good idea to check but I have not seen an MLS gasket fail. 1996-1998 were the problem children.

    My two bits...

    Cheef have done quite a few head gaskets with the new multi steel plate gasket type. They still leak but are a lot better than the old type. Some of these you can retorque the head and see if the bolts where loose. I will usually use copper coat on every one of these type of head gaskets. Have not had a come back yet. But you are correct the updated gasket works a lot better but they can still leak. Anyway it is better to be sure on the leak before you start to remove something like the trans.

    Agreed. You can't repair something that isn't broken. Repairing something that isn't broken won't fix what is.

    I use the OEM goop in a can "MoPar Spray Gasket Sealer" and thoroughly (drippy) coat and allow to set up before installation. I "finger" same on head and block. As long as the head and block are straight, I clean and do not machine. Small erosions I clean scrupulously and fill with JB Weld, let sit for 24 hours, then carefully scrape until flush. I use the OEM recommended torque sequence and final 90 degree torque to yield. Inshallah...I have had zero comebacks also.
