I’m surprised karthief didn’t give you the punctuation scpheal. ;) Mine leaks a little too. But, a little punctuation goes as long way.

I am going to summit today and get the seal .
I used this seal with good luck after the stock replacement leaked worse than the original:

Do you put the plastic guide on the crankshaft, and slide the seal on ,or use a seal driver ,or do both?

So far so good. It's been in about a year and a half and isn't leaking. It's not in the instructions but it must be installed dry.
 
Definitely use the plastic guide that comes with it to slide it over the crank shaft, and your probably going to have to use a seal driver to get it to seat all the way.
 
I used a 4" PVC plumbing cleanout fitting to drive in my seal. Worked out well for $2

Rear main seal still leaks, I even put the Teflon seal in ,my question is, do I have a bad crankshaft or is there something else causing this.pcv working good I am at my wits end about this.

Did you put it on dry or oil the perimeter of the seal first.
You sure it's the RMS and not the intake, valve cover gaskets, oil pan or even the flywheel bolts?
