I have a freind that has a 1995 2500 I just put a long block 6.5 TD in rebuilt turbo' injectors #9 chip in the injector pump new OPS new lift pump. Runs great but it run 80 lbs of oil presure is this ok or is there a problem

That would depend on the oil pump, but that does seem high

Should be around 40 at very hot idle

International deisel out of New York rebuilt it all they say is that it is a new oil pump. My 97 has 308;000 on and it runs around 40 at 2000

Oem factory oil pump is less than that - some a\m pumps advert to increased oil pressure intended for hi-mileage engines, or hi-perf engines

That's within factory spec. Supposed to be a minimum of 10 psi per 1000 revs.

I just put a new engine in mine also with a high volume high pressure oil pump it runs about 80 psi when i first start it but goes down when warm. when warm it idles at 40 psi and about 60 to 65 psi at 2500 rpm. if yours is staying at 80 all the time you might want to check your oil pressure sender or grounds.

I've had problems with my pressure gauge reading high before and them jumping around, I had cleaned up my ground straps and seems to be working right now.. maybe help

 

[oil burner]

It may have the late model ['97-up] oil pump intended for the oil spray piston blocks. They put out a higher volume ,not sure if it would build more PSI. Have not put one in an older engine yet. Just a wild guess.

INTERNATIONAL DIESEL uses all 506 diamond blocks with sprayers in there engines(as per ERIC, service manager over there).
