As you can see, I have successfully removed the OEM plug and replaced it with Anthony Dail's. I used a custom-made T handle wrench to remove the OEM plug. Surprisingly, I didn't require much push-pull force on the handle (5" each side).

I noticed movement at the joint to the left of the plug bung (Jeez, did I just write that?). I can move the pipes in and out slightly by hand and I found about 1/2 oz. of coolant on the garage floor.

Does anybody know how this joint is secured? I can believe the torque I applied could have broken welds! Is is press-fit or crimped? Can anybody else move this joint by hand? Does the crossover tube come as one or two parts?

I guess I'll start the engine to see how much it leaks. I'm curious.....

.....idled the engine for 30 minutes and no leaks whatsoever. I was informed that this joint has an o-ring seal. Is this correct? If so, can I presume that it explains the looseness - slight movement under torque load to the plug and slight leaking/weeping when cold, and rigidity with no leaks when hot?
