dash gauges are very very inacurate.
Suggest you temp install a mechinical gauge to get a true reading.....knowing the oil pressure will guide the next step.

V8 engines that era will have low oil pressure...

Even an aftermarket electric gauge is much better than the factory one.

ok. i never worried about the low reading, but the trucks been having some issues which i cannot figure out and my dad said "well if the oil gauge is reading low, start there."

Mine dose the same thing.

Same here,it is normal to have about 6 pounds at idle.

[charlie1935]

I know the factory says six lbs. is ok at idle but I have never had any vehicle have that little except my 1934 Chevy that did not have a full pressure oiling system.
All the mopars I've had idled around 25 to 30 lbs.

[nemesis_SS]

25-30 at idle? my haynes says 8lbs is ideal, but i figure with age 6lbs is acceptable.

how do i get an accurate reason on the oil pressure? im gonna drop the pan today and check for a sludge blocked pickup screen. i just feel stupid doing all that work when i dont really even know if my prussre is low

The best way is to hook up a mechanical gauge and see what it reads. Some of the chain parts stores may have a loaner you can use without buying one.
