    Default Rear main seal Gen 3

    I have an oil leak, and its dripping from the joint between bellhousing and engine. The sump has been weeping aswell, but not bad. Is it a big job to change the seal? Any advice would be appreciated.

    Cheers

    Yeah I figured a pain in the ass! Do I do the sump gasket while the gearbox is out? Will it drop down far enough?

    do the rear main with the box out, put the box back in and do the sump gasket by dropping the k frame down a bit and supporting the motor from the top

    Will putting the front wheels up on ramps be high enough to get the box out? Also how far does the K frame have to be dropped to get the sump out, and can this be done on the ramps aswell or on stands?

    Try some HM oil like Shell helix Plus High Mileage or Maxlife from Valvoline. Even try some Auto-RX additive. Seals leak for 2 reasons, they are dirty-shrunken from poor oil and changes, or they are damaged. THe oils and additives can cure it from the 1st one, cleaning around the seal so it seats properly, and also using seal swellers to bring them back to original. It its the second one, damaged, it must be replaced, you just never know, but cheaper and easier to use a oil to see if it stops it. If you use the oil and additive, and it starts to leak a lil more, you definately know it was cause the seal was dirty, it will eventually stop or slow.

    no you will need car stands.its a big job geting the box out on your back. Took me 3 days lol and heaps of piss but i reckon i could do it in a day now that ive done it before.
