looks like haynes manual states oil pressure to be 14 psi @ 600 rpm, and 43 psi @ 5000 rpm. can anyone confirm this? . . .
About right for the 2.5. However, I'm not sure that's what a gauge would indicate because that spec is for the pump capacity (see attached), whereas the likely measuring point (e.g. where the oil pressure warning light switch is located) is somewhat downstream, after the oil filter.
