ALRIGHTY BOYS, and ladies.... I stripped the engine down to the pistons to check my piston walls, no damage was detected. I got her all put back together, and while I was at it, I ordered some new OEM injectors, thinking that might be the cause of any possible engine flooding. And now she runs great, I'm really hoping that the new injectors will also solve my low MPG's problem. Since the conclusion of the community there was that I possibly had a fuel leak, though, I couldn't find where. So Two birds one stone. As far as the engine being frozen before, I have no idea what caused the engine to sound like a "diesel truck" I pulled the water pump, and everything was completely fine, so IDK... but its not a problem now. I popped two freeze plugs out, both in the hardest place possible to replace them, but I managed to jack the engine up and install the neoprene fastener replacement, they seem to be working properly... for now. It seems I almost entirely avoided any damage to the engine from the deep freeze. I say "almost" because now my rear main seal, which was leaking like a drop or two a day, has enlarged to many many drops every time I run the truck. I guess I can't complain too much since I avoided a much more expensive fix, but now I'm cursed to be continually checking my oil level until June when I'll be back home with my floor jack to drop the transmission. Oh, Also, I fixed the issue I was having with voltage as well. I was having random times when my truck would drop to 13.5 volts or lower volts while running, which was... concerning, but I couldn't find what was wrong. turns out the Passenger side fire wall to engine block ground was not properly installed. So, when I put the engine back together this time, I was able to properly connect the firewall ground to the cylinder head, now everything is running perfectly at 14.5.
In conclusion. I fixed my gas flooding issue, and, I hope my bad MPG's. I fixed my popped freeze plugs, and I got my voltage regulation problem solved. I gained, however, a larger rear main seal leak. Can't win them all, but it would seem this break down has been an overall positive turn of events. thanks for every ones help.
