questions about oil pressure
 

Hi all. My '76 CJ5 with 304 has been showing low oil pressure on the
little aftermarket gauge that was installed on it when I bought it.
When I first start it up and it's cold it will idle at about 800-900
RPM and read about 60 psi of oil pressure. As it warms up for 4-5
minutes the oil pressure drops to around 25 psi or so at idle of about
700 RPM. If I take it out on a short highway trip, then after about 5
miles of crusing at 3000 RPM, the oil pressure drops to about 20-21
PSI at that 3000 RPM engine speed. I got these readings today, just a
few minutes ago right after installing an oil pump rebuild kit that
consisted of 2 gears, a gasket, and a spring/piston for the oil
pressure relief valve thingie. My engine temp never reads above 210
and it idles just fine even after highway cruising for several
minutes, but when it idles after the highway trip the oil pressure is
so low that the gauge doesn't give me an accurate reading, it's like
it's hard to tell what the pressure is once it drops to arout 5 PSI or
so. So all in all my Jeep starts right up, runs great, stays cool (no
more than 210 degrees) idles fine, has plenty of power, doesn't blow
any smoke out of the tailpipes, no backfiring, etc, etc, etc, but the
oil pressure reads low. I'm not sure if I should be worrying or not.
I doubt the gauge is bad since it reads 60 PSI when I first start up
the Jeep and it's cold. It's one of the mechanical gauges that has a
high pressure oil line running straight to a little screw-in fitting
on the engine block next to the oil pump. Seems like if it reads ok
when cool that it would read ok when hot. Can I get some input from
y'all as to whether or not I should be worrying or what I should do
next? Thanks for taking the time to read all of my ramblings.

Sounds like it is overfilled...the oil is foaming....I have the same
problem when I accidentally put in an extra quart...draining some out
helps me...
