    Thing is what dose it look like trans oil or motor oil. In this area could be transmission seal or rear motor seal. Could be coming from the torque converter. Rear motor seal is a two part seal and where prone to leak. Take a sample of it to a local mechanic. The smell test should tell you if it is trans fluid or oil. :praying:

    Color might help also. Red is tranny fluid, darker is oil

    Yep Quick bird. From what I see it is pretty thick so tend to think it is motor oil. Hate to replace the rear main seal it is a pain. If you have to do the rear might as well do the front one also while you are their. With the pic. he cut off the floor where it would be puddled.

    Check the right rear valve cover gasket for a leak too, this area is notorious for leaks and it will run down to the pan area causing you to think it's the oil pan or rear main

    I agree with that. The valve gasket's on all motor's due tend to leak at the back after a while. Think because of all the heat near the fire wall. Hope that is the problem easy fix.

    So have you discovered that the valve cover is leaking. Just asking. I changed mine on the 383 motor in my car their was a lot of oil on the block at the back. Plus wanted to look in to the valve area to see what it looked like as far as being dirty or any thing loose. Just checking thing's out had not cranked the motor yet after buying it.

    Do you recommend a adhesive for installing the new valve cover gaskets?

    No use to wipe them with a coat of motor oil if they are not the rubber type. Just a lite coat should do it. Other guy's go crazy with the sealers. Some sealers can foam in the engine and close up oil ports from what I have read. Use to use Permatex back in the day on some gaskets. Now they make all these new product's still like a gasket. Like Lock tight for nut's and bolts.
