No, his '97 TJ's oil pressure gauge (when it is working properly that is) actually does indicate the true oil pressure. It was later TJs (probably after 2001 or so) when they reprogrammed the oil pressure gauge to only indicate the absence or presence of oil pressure.
Knowing of the issues that early '97/98 TJs had with their oil pressure senders, as my '97 TJ had as well, I'd bet it's nothing more than a bad oil pressure sender which can easily be swapped in five minutes.
Mine would do the same thing, indicate zero oil pressure once in a while, which I have to tell you that when it happens on a lonely dark remote desert road as happened to me, it is not a fun thing to have happen. That bright red Check Gauges light and the zero oil pressure indication will really get your hear pumping when you still have 25 miles to go and you haven't seen another vehicle in an hour and you're in the middle of the desert 75 miles from Las Vegas on a small two-lane remote desert road.
