Glad it worked for the OP, just 
MB
We'll see if it works for the OP , I would imagine it will take a little time to tear it up if that is what did in his lip seal ...
Here's hoping it works for you Troy

One more thing that I saw today that blew me away. I was at a friends shop today and I saw something that just killed me. There was a aftermarket billet seal retainer just sitting there. Next to it was a factory seal retainer. I matched the two of them back to back and the overall height was the same BUT the aftermarket cap....where the seal sits was OFF CENTER by .040!! That is a MILE off!!!! Tomorrow I will go back and take a picture for everybody viewing pleasure. 
Gee, I seem to remember that exact issue with a certain sellers cap ...

....no, it is in correctly. The lip goes to the inside of the engine. The design is so when oil is pressed to the seal it forces the lip into the crank making a tighter seal.
I am 80% sure that the leak is not due to oil leaking between the crank and the seal but rather between the seal and the engine block/seal retainer......that is my thought.
First off, your seal does indeed look to be in backwards. Th edge of the seal makes a sort of V, the point of which should point to the back of the block.
Second of all, if the retainer is too tall your issue is the retainer, NOT the seal.
Finally, crap parts is still crap regardless of the price, coolness factor or bling. The OEM retainer worked for years, why change it.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

Today I installed another rope seal in a friends car. Tomorrow we will see if it is fixed. He is on his 4th try. On try second try this is the cap that he took out. Look how off everything is. The mounting holes are off, the crank and seal area are shifted off to one side. I can't believe this is sold to the general public!! 
Hmm..
That other car may be that B7 Charger... 
Just my $0.02...

From what I read, Troy is using a OEM retainer.
The retainer that was pictured as "off" was another one from a friends shop.

Regarding where the seal rides, 2 questions...
Was the crank all the way back, as in, the end play?
Was the spot where the seal was possibly a worn knurled area?
Thanks.
Thrust is at minimum spec.....if I remember it's at .007 and where that seal rides it about .030 in front of the knurling.
New Eagle crank so the knurling is new and looks good.
Here is a picture showing where a lip seal rides on the crank. It is far in front of where the knurling is.
.......... Actually the only time I had one that never leaked was when I installed it BACKWARDS from the above pic. I always thought the knurling was there to direct the oil back into the engin and that the seal had to ride in the knurled part of the crank as long as the knurling was smooth. Funny that when I had the motor re-build the seal was installed the CORRECT way (same crank/sealholder and block)and then it leaked like crazy. On a recent build, I used the newer orange seals (440 source)with some hylomar in the groove befor the seal and the seal installed with the lip inward and got a good seal with that motor.

I have two updates for you all. On my Dart, I just came back from a 25+ mile cruse and there was no oil on the crank at all.  I had some engine oil on the trans but it was all residual oil left over from the past leaks. So far she is looking good. On the Charger that I put a rope seal in yesterday....she too is looking good. We started it up this morning and let her run for 25 minutes and she is looking good as well. One thing that I forgot to mention yesterday about the Charger. That crank in that engine is a Callies crank with NO knurling at all....she is polished smooth. Ones again, I'm not trying to tell you all that rubber lip seals don't work. I have installed many of them with very few problems. What I am saying is if you have a problem with a rear main leak and you know you installed it correctly don't rule out the old fashion rope seal. However me on the other hand will never install a rubber seal again!!

Glad ya got it. I've got a couple going together & after your thread I'm undecided which to go with as I have several rope seals handy & I think both cranks are heavily knurled
