a friends b16s oil pressure 17psi at idling. is this normal?
autometer mechanical oil pressure gauge teed off at the sending unit with the turbo oil feed line.

 

uh no...

 

idle should be like 40-70 it really varies.

 

I would check for a kink/pinch in the oil feed line to the gauge, just to make sure its ok. You should be running alot higher than that, or your oil pump took a ----.

really? thats on idling only. but when revving it goes to 80psi.

 

check all the lines no leaks. could it be the pil pressure gauge? its back to 20 psi at idling? what should be the pressure when idling?

 

Should be ok.... spec is 10psi @ idle
50psi @ 3000rpm, those are minimum spec readings.

Hehe... my tired old high c/r D16A6 makes 0psi @ idle once at operating temp (after a hard drive) and it still runs.
I suggested to the current owner of the engine to run 20w50 in it through the summer, and to not be shocked when it grenades (should be any day now).

edit=spelling error correction

 

BTW, the aforementioned D16 has been running like that for well over a year allready. Once the revs come up, so does the oil pressure, so it makes pressure when under load, which I think is the most significant factor.

 

I have a d16y8 and if I am low on oil my gauge reads 14-17 psi but when I give it gas it runs right up to 80 psi. It will fluctuate diffently. I can kinda tell when oil is low. If I have 4 full quarts it idle's at 25 psi.
