Minor coolant leak, but it's SITM or bust.
The irritating coolant leak that I've been chasing the past couple of days stems from two sources:
1. The lower radiator hose. It was moist around the metal clamp and had a drop of coolant on it. I loosened the clamp, re-seated it and tightened it down. Hopefully that one's cured.
2. The coolant passages at the back of the engine on each head were moist around each of the seals' two bolts. I cranked the passenger side one down last night, but there was still coolant on the ground today. I pulled off the airbox AGAIN (getting tired of this) and found one of the bolts on the other side of the engine wasn't totally tight. So, I cranked that one down, too. Hopefully this will stop the leak. Either way, I'm going to SITM with a couple gallons of pre-mixed coolant. The heater valve is dry. Are these fittings supposed to have a gasket or something??
I tried to add refrigerant to the AC system, but one of the hoses going to the compressor still isn't holding the r134 in the system. It's got a new o-ring, and it's tight. I have to assume that it's not threaded right or something else is amiss. Oh well. I've had AC for a grand total of 3 days since I owned the car. What's a few more?
I also discovered the vacuum fitting near the brake booster was disconnected. Hooked it up and the HVAC system operates as it should (other than not having AC).
SITM...here I come!

Hey Dave, the Hemi support vehichle option is still available. Just say the word and I will make it happen. I would like to say that it will keep up with a school of sharks, but the computer shuts it dowm at 130MPH. But, it would probably tow 3 sharks at that speed. Have a safe drive to SITM and I will see you there. If you don't have my cell number, PM me.

Thanks, Jack. I'm gonna cross my fingers and hope for the best. I'm going to take it nice and easy. No need to tempt fate with top speed runs.

Dave,
Although I haven't BTDT, I recall that when my shop was unable to charge the system, it was because the compressor wasn't running; turned out it was a plug in front the wiring harness / passenger side TB cover. Obviously the system needs to be running to fill properly.
Of course, you've probably confirmed the system is otherwise operating properly, but my situation had a couple of so-called Porsche specialists stumped for a bit, so I thought it worth mentioning!

There are gaskets on both of those fittings at the back. Id also add some sealant to the threads of the botls as well. Those bolts get ugly when they rust up and seize because of water in the threads. If you dont have gaskets, just run to Autozone and get a small role of that gasket material and make your own.
...and dont just "crank" those botls down, they WILL strip the threads in the block!

Jack-
I have your cell # and we're driving together. I'm bringing my tow rope in case on an emergency, although I'm expecting smooth sailing... errrr.... driving. See you there.
