Re: Blankety-Blank Rear Seal!!!!
I would say the oil gallery plug is more than likely the culprit.

Jerry, I had to try three times to stop that "rear main seal" leak on
my 88. First the rear main - helped a lot but still had a drip.
Next, I noticed that when I put my hand up behind the oil filter I got
a little oil on it. Darned oil filter adapter was leaking, running
back along a casting rige and dripping! Not a trace of oil coming
down, it was all running back and dripping down the shield (the 88 has
a tine shield all the way up behind the flywheel). OK, that slowed it
some more. After that, I decided to look really close and sure
enough, the front seal was leaking a little and pulling the same trick
- blowing back and running down just like a rear main. Once I wised
up, I could find those blowback traces with a rag but they sure
weren't obvious. I haven't seen another case like that but it's worth
a few minutes to look. Any chance that the crank has a rough spot
under the rear main seal?

Re: Blankety-Blank Rear Seal!!!!
Thanks, Will. I'll check it over again today. I let it sit overnight for the
sealers to cure, but I have no faith it's been fixed this time any more than
it was before. The "old" seal came out looking like new, so I don't think
the sealing area's scratched up. The valve cover's sealed as tight as a drum
and the filter area and front seal are dry as a bone.
Only other thing I can think to do is to pull the trans and the separator
plate to sdee if the galley plug is leaking. (If I do that I GUARANTEE that
won't be it!)

sealers to cure, but I have no faith it's been fixed this time any more than
it was before. The "old" seal came out looking like new, so I don't think
the sealing area's scratched up. The valve cover's sealed as tight as a drum
and the filter area and front seal are dry as a bone.
Only other thing I can think to do is to pull the trans and the separator
plate to sdee if the galley plug is leaking. (If I do that I GUARANTEE that
won't be it!)
