Your post is probably better in the main portion of the forum. I also hope for your sake that you didnt do any major damage. If your going to run the car for 5 minutes and change the oil again, you might as well add some seafoam to the crankcase during the first initial run. I have no idea about thread lock/sealer. I have usually just replaced the bolts which came with new sealer/locker already applied.
BTW a friend of mine had this SAME thing happen to his bonne with the 3800 II. It was missing badly and he had to keep the rpm's up in order for it to not die. When he got home and shut it off, it would not start, not even turn over (hydrolocked). He tore it down and found that he had filled his cylinders with coolant. Upon replacing the UIM manifold and LIM and UIM gaskets, the car ran great. No more issues, no wiped bearings or bent rods. Just a little reassurance (I hope). Good Luck!
