HELP!!! new rear main seal and oil is pouring out

I put my 03 2.4 tj in the shop to get my rear main seal replaced and while driving it just now i noticed more smoke coming out. I pulled over and the oil was pouring off of my transmission and on fire. I put it out but it almost ran dry.
The oil is coming off of the back of the motor. Is there anywhere else on the rear of the motor that could leak that badly besides the main seal or did the shop just do a crappy job?
Help!!!!

I think the shop should be looking at this. I would suspect improper installation.

Drain plug has some sealant around it. Im going to take it to a self-serve car wash in a bit and spray down the motor.
The shop is only maybe a mile at most from me and i drove it home and then maybe a mile after that before it started smoking really bad. Pulled over and put out the small flame that had just formed and was going to drive like 10mph to a store that is about 300 yds away. I turned around and drove about 100ft and got under a light to check the oil. It was almost dry. I left it there until i can get some oil in it today and drive it home.
I always park on the street in front of my house. I checked it for a stain. There is a very small stain that formed in the 6 hours that it sat before i drove it.
Im not too happy about dropping $550 and nearly losing my engine

If it was mine I would not clean it off. I would want the shop to see it. This way they can't claim you fooled with it.

Phone the shop, tell them what has happened, and ask what they are going to do about it. If they are reputable they will make good. Don't offer to fill it with oil and drive it there, see if they will get it towed (at their expense). Now that you know about the problem, don't do anything that might be construed as contributing to it.

Im going to have my buddy pull it up there. When i went to pick it up, i checked the oil and the dipstick was completely dry. Put four quarts in it and drove it back home. It's now pouring out again.

If you have manual transmission, you may now have oil on the clutch as well. Not a good thing

"it" being the rear main seal? If an engine is overfilled with oil it can cause higher pressure than it can handle and something will give. That something could very well be the rear main seal.

The problem with filling it and driving it after the initial problem is now you've got to convince the shop that you didn't cause the blow out yourself by over reacting (I'm not saying you did, but they might) to what they could call normal burn off of residual oil resulting from the job itself.

Good luck and let us know how it turns out.

He tried to tell me that a possible faulty pcv valve caused pressure to build up and blow the seal. He said that pressure had to come from somewhere. First time that i have ever heard of a pcv blowing a seal, but they are checking on it.
If there was too much oil then thats on them. He said that they are taking care of it...

If the PCV is clogged the old seal would have blown out too, so if you had it replaced because of the typical slow leak then PCV is unlikely. If it was overfilled by the shop they might take issue with you refilling it and say you overfilled it. Doesn't make a lot of sense but something I could see a less than ethical shop arguing. Could just be a fudged job.

Regardless, the best course of action when something goes wrong like this is to never do anything but call the shop and have them tow it back. Even something as benign as refilling the oil could create a bone of contention. I wouldn't have your friend pull you to the shop either, make them tow it (no matter how close).

If there was indeed pressure built up it seems to me that the dipstick would be the most likely place for the pressure to relieve initially.
