That's my plan, as soon as I heal my "wing". I had major shoulder surgery,
and I'm in the 4th week of recovery / rehab now.

The Jeep has been relegated to driveway duty since the problem got
consistent, wife is rolling the miles up on the Explorer.

That's the sucker. One thought: I replaced the oil pump in my 4L after it
dropped something like 15 PSI across the board on one 175 mile run. When I
pulled it, it was obvious that the problem was a break in that thin paper
gasket between the pump body and the block. Since the old pump had 175,000
miles on it, I went ahead and installed the new one anyway but I later ran
a flow/pressure check on the old pump and it was still good - that one
leaking gasket was apparently the whole problem. How careful were you
about cleaning the surfaces when you mounted the new pump? It could be as
simple as that. Small leaks on the high pressure side cause big problems.

Well, I was careful, I did not make it a top priority though. The old gasket
came off with the old pump, I wiped the mating surface with a shop towel
before slipping the new pump and gasket into place, but that's about it,
other than torqueing the pump bolts.
I have read before the bulletin about the gasket failure, but the old gasket
seemed fine to me.
