Rear Pinion Seal Leaking

I had a professional replace the ring and pinion in my '68 Chev Camaro. It is a 10 bolt with the small gear.. Whenever I drive the car, after I park it, rear end fluid puddles on the floor under the rear yoke. I have replaced the seal three times and it still does it. My first thought was a clogged rear end vent, but I removed the protective cap and blew compressed air through the tube with the rear cover removed, and the path seemed to be unobstructed. No fluid seems to leak out when I drive the car, just after I park it, and most often after a long drive. It doesn't seem to leak just driving down the street and back. The car has an Auburn posi unit, with 3.73 gears. Please help!!!

Without being there to see it, its hard to say whats going on...
But if a professional installed it, take it back to him and let him look it over.
IT sounds like the problem is isolated to the pinion flange/seal area..
Remove it and inspect everything...
Preload set correctly?
Pinion angle ok?
Are the seals damaged?
Just thinking out loud here.
