Re: oil pressure at the lifters at idle

The sender for the light, at least on my car, is at the junction block where some of the oil goes to the oil filter, and some to the oil line that leads to the lifter galleries. What the sender is reading is before that split, though granted there should be little difference between the pressure there and the pressure as the oil goes into the lifter gallery.

This service counselor says the pressure should be no less than 5 psi at idle (10 MOH). Anyhow, just wondering if anyone has actually measured it with a mechanical gauge while running, e.g. in lieu of or in addition to the pressure switch for the light.
