my temporary fix is still holding up!

It may not look pretty and may just be a temporary fix, but better than dropping some cash right now.

[Repair] Rear Main Seal Replacement

Try this site above, it helped me save a lot of money
The only advice I have is when it is time to put the gasket and oil pan back on. My recommendation is to put the gasket onto the engine block first and then put the oil pan in place. Also make sure the gasket seats nice inside the rear bearing cover!!!! That is where I made my mistake and had to do the job all over. I was trying to put the gasket onto the oil pan first and then put them in place together. Doing it that way you will never be able to get the gasket to sit right in the grove (bearing cover). They sell a gasket spray that is sticky that will allow you to place the gasket onto the engine block and then give you time to put the oil pan in place. Also what I found out after the fact is that you can buy these screw clips that screw into the engine block. These clips will allow you to snap the gasket into place and oil pan. Once they are in place you unscrew the clip and replace it with your original oil pan screw.
Good luck

Leaking about 5 drops a week. I'll check the oil pan screw, but pretty sure it is the RMS.

Looks like oil gathering around the thick black rubber, between the oil pan and transmission bell.
That would be under the RMS, correct?

Also do you need to take that thin plate off on the trans bell to get to all the oil pan bolts?

Before spending your money to get the rear seal changed, check and make sure that the last two pan bolts closest to the seal are tight. My friend had the same problem on his 4.0. We tightened the two bolts and his leak stopped.
Good Luck!

The last 4 on each side were not tight.
Lets see if it helps.
