Chris,
Some observations / comments:
1) Since you have also provided photos of the oil pan leakage I assume
you're going to replace the gasket as well and you saw the email from Chuck
Boyd which stated; "Auto-Zone shows Fel-Pro oil pan gasket # OS30471C as
standard for the 350 diesel and is shown as optional for the 455 and 403."
That's the gasket with the steel core that won't squish out.
2) While the oil pan is off you could add a second drain as per:

3) As far as the rear main seal goes from the emails that have been sent in
I am going to give it a go if I mine leaking when I remove the oil pan to
replace the gasket.
Good luck,

I noticed my rear main seal must be the cause of the leak. I read the thread
about changing it with a Ford 460 seal without removing the crank. Not sure
if I want to tackle this now, or wait for a rebuild...
