The 98 Yukon is running now -- purrs like a proverbial "kitten" and I'm happy as a proverbial "pig in s*#@" -- for now, let's hope it keeps on. So far no leaks or codes.
I took the advise of a friend who I sent a link to my first posting:
"
Subject: RE: What's Your Advice?
If it is in the base no problem if it is in a casting hole still no problem if it is where something is going to hit it a really big noise .but still no real problem
Turn motor over slowly with starter with ignition disconnected so it will not start if it binds up you will have to drop the base and find it. Unless you drop the base you are going to have to buy another on if it will not come out the base plug hole. Most base plugs have a magnet to catch metal filings so will eventually catch and hold the socket
good luck

I cranked it several times with the coil wire disconnected and there was no sign of binding. I'll drive it a hundred or more miles and then change the oil and see if the bit and adapter come out the drain.
I did have a few drops of oil on the front cross member. I hope those were residue from the power steering hose I had replaced immediately before starting the intake manifold job.
Much credit goes to "Suburban-97" in the Chevy Suburban forum.
