Default Rear Main Seal Question?

When i replaced my clutch i noticed i had a rear main seal leak. I replaced it, and now 3,000 miles later its leaking worse than before. It recked my spec stage 3. Do you think i have another problem, or maybe just a bad rear main? What other problem could there be? I appreciate all feedback.
thanks
james

Did you put oil on the seal or crank befor you installed it? The front and rear mains have to be installed dry because theres teflon that "melts" to the crank to form the seal.

I hear it both ways ...

I've had GM techs tell me both ways and I've read folks here doing it both ways ...

I put a light coat of oil on the crank and none on the seal
