freeze plugs?

Ok, this is getting ridiculous... bought my 02 Libby Sport. 2 weeks later, a head gasket goes. I replace both with Victor Reinz gaskets. The one on the passenger side doesn't seal (yes, I had the heads shaved and pressure tested). I get a friend to drive an hour and a half to help replace the passenger side again because of my very bad back and neck that is worthy of 2 surgeries over the course of 9 years. We replace it again. Overheating stops, Runs like a brand new one. Wonderful. Love my Liberty. Here's the "but". But, today, as I was leaving the store, I notice dripping under my Jeep. I get it home, as it is not overheating or any of that jive, get it on the ramps and discover that the water is coming from between the bellhousing and the block. I am thinking freeze plugs because, maybe, someone ran tap water and not distilled. Other than a freeze plug or, God forbid, a cracked block, are there any other places the water could be leaking? Also, will I wind up killing myself or someone else from the aggravation of doing the freeze plugs on the back of the block? The pics attached, if they do indeed attach, show the wet spot on the bottom of the bellhousing. Thanks in advance.

C'mon. No one has had to deal with freeze plugs on a 3.7L? Could be just mine. Sounds just like my luck.

I had to rebuild my engine because I lost all coolant from a leaking freeze plug on the back of the passenger side head, and the motor got hot, and it dropped a valve seat, and it destroyed 2 pistons and a head. Finishing up reassembly now.

Anyway, I replaced all freeze plugs with brass while the motor is out. I don't know of ANY way you could do the freeze plugs on the back of the motor without pulling either the engine or the transmission. The plugs are recessed in the back of the block up on top behind the flex plate. There are 3, although one appears to be just a plug behind the balance shaft, and does not appear to hold coolant. Maybe just to hold oil in. All the freeze plugs on the block and heads are the same size.

Good luck.
