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!)

Re: Blankety-Blank Rear Seal!!!!
The valve cover does a really good imitation of a rear main seal leak. I did
the same as you, replaced the seal and pan gasket twice, and on the test
drive after the second go around, I parked on a hill and could literally see
the oil flowing out of the valve cover. The cork gasket is about a quarter
inch thick, and when it cracks, the two pieces draw apart from one another,
and create a HUGE HOLE that the oil flows through. The oil runs down the
back of the block, through the bell housing and out the bottom of the clutch
inspection plate. It looks for all the world like the rear main is leaking,
but the oil has travelled all of the way down the block before dripping off
the bottom of the bellhousing.

drive after the second go around, I parked on a hill and could literally see
the oil flowing out of the valve cover. The cork gasket is about a quarter
inch thick, and when it cracks, the two pieces draw apart from one another,
and create a HUGE HOLE that the oil flows through. The oil runs down the
back of the block, through the bell housing and out the bottom of the clutch
inspection plate. It looks for all the world like the rear main is leaking,
but the oil has travelled all of the way down the block before dripping off
the bottom of the bellhousing.

Re: Blankety-Blank Rear Seal!!!!
The valve cover does a really good imitation of a rear main seal leak. I did
the same as you, replaced the seal and pan gasket twice, and on the test
drive after the second go around, I parked on a hill and could literally see
the oil flowing out of the valve cover. The cork gasket is about a quarter
inch thick, and when it cracks, the two pieces draw apart from one another,
and create a HUGE HOLE that the oil flows through. The oil runs down the
back of the block, through the bell housing and out the bottom of the clutch
inspection plate. It looks for all the world like the rear main is leaking,
but the oil has travelled all of the way down the block before dripping off
the bottom of the bellhousing.
