99 SATURN SC2 1.9 DOHC Ideal Oil Pressure??

Just changed the crankshaft, main bearings and rod bearings. Seams to run fine. What is the ideal oil pressure hot at idle?? I have @ startup cold, 60psi and after it get hot, it runs between 15 to 18 psi @6k rpm. I have not changed the oil yet to get the assembly lube and old stuff out yet and I suspect it will get a little better after I change the oil. Just curious if you think I'll be ok, it makes me a little nervous because of all the work and expense I did. Thanks!!! 99 SC2 - 80k miles - DOHC

You said the pressure is between 15-18 psi a@ 6k rpm - did you mean 600 rpm? I think that 15-18 psi would be fine oil pressure at an idle. And what pressure gauge are you using to measure that? My impression with oil p. gauges is that they arent very accurate, especially at the low end of the dial. Im happy if they are at least consistent from week to week.
