Our current game plan is this - If the IPR is proves to not be the cause, the HPOP cover will come off and we will pressurize the system through the top of the pump (is that possible, by pressing a rubber air hose fitting onto the hole on the top of the pump?). If the leak is not inside the HPO area, then the valve covers will come off and we will pressurize the system again to search the oil rails and injectors. Does this sound like a reasonable way to proceed?

Are the parts expensive, or are you just talking labor?

Good point. I'll verify the test wire connections when retesting the IPR.

Brickie... If that's a PITA for your wife, then don't worry about it. We may not get back under the hood for a couple of weeks (heading to Cancun the day after tomorrow). However, it may be nice to have the (cheaper) parts ordered and here by the time we get back.
Thanks a ton!
