Rear Main Seal

Ive got an oil leak between where the transmission and the rear of the engine connect. i have been told that it might be a rear engine seal. How hard is that to fix? the only way i have heard of is tearing out the engine/transmission and transfer case. is there an easier way of doing this? do i need to do this? or could it be something else?

Thanks for all your help.

P.S. it is a '83 Toyota 22R

Read this , find where they use a hoist to hold tranny. Once you got trans pulled far enough away. you can get to the seal. Other wise, yank motor.

Sorry, this is a newbie forum, but SEARCH!!!!! There are a bunch of write ups and links here dealing with replacing the rear main seal. That said, look at this recent one:

What engine are you using? some have a two piece seal that you can drop the pan. remove the main cap and by using a norrow punch push the top seal out far enough to grab it with a pair of pliers put some oil on the new seal and push it back in. Place the bottom seal in and reinstall the main cap. Make sure the seal is faceing the right way and retorque the main cap

If you do replace the rear main seal, make sure you get a sleeve for the crank. Your crank seal surface is probably grooved from the old seal and if you install just a new seal it will start leaking again in just a few thousand miles. The sleeve will cover the grooves and give a good, long lasting seal.
