when at full operating temp... and idleing around 750-800 my oil pressure sits just below (maybe 1mm) below 60 when driving... and holding anywhere between 2500-3000 My oil pressure is just below (2-3 MM)

110. Is it normal for a (rebuilt) motor to have such high pressure? Do you guys recommend purchasing an aftermarket pressure guage, just so i have more sense of whats going on in the engine bay?





thanks for the input



On a side note, my old tired motor with 208 K during idle would have just above (1-2 mm) 0 oil pressure... and while driving would have right around 30lbs or so

 

mine has (well had) 30lbs at idle and 60lbs after the 2k range. I got a completly stock engine though. I need to look at my car as my oil pressure has dropped it doesnt hit 60lbs anymore not even at 5k +.

 

mine is like a mini tachometer

 

Damn that sounds high. You may want to double check with a different guage. My 88 (77K and runs strong) reads around 25 at 800 rpm and 60-75 from 3k up with 10W40 (I have noticed a diff in readings with oil weight too). This is on an Autometer Phantom electrical guage with the sender mounted below the oil filter.



My other one with 169K & stock guage reads 15-20 at 800 idle and barely hits 60 from 3k up....its getting tired.

 

Thats what my old n/a was like.

test is with a mechanical gauge to be sure.

 

yeah, the guage (has 208,000) miles on it. It self is prolly getting tired.. along with my speedo too



It bounces below 20.. kinda amusing.

 

The oil pressure senders are known to go out

 

you should try lubricating the speedo cable.
