i just noticed that my stock oil pressure gauge is reading just a lil bit above the 0 .. i remember before when u accelerate it rises , and on the freeway it should be about rite below the 60 psi mark . now its just a tad bit above zero .. i checked my oil level it was low then added more oil to full , and test drove it ,but still a lil above zero . i know the gauge aint broke cuz it moves . is this gonna hurt my engine and turbo's having such low pressure ? im afraid it might not be pumping enough oil through the turbo's and all ? i just had my turbo's rebuilt to , dont want to mess it up again .. anyone know what it might be ???

 

please do a search.

 

Clean the connection from the sender.

 

yes, its just the sender.

 

Probably the sender. I had the same problem: oil pressure was fine when the revs were up, but at idle the pressure was very low or sometimes zero on the gauge, it seemed to be worse on hot days. I cleaned the connection on the oil pressure sender unit and it helped a little, temporarily. Finally put in a new OEM sender unit and the oil pressure reading has been normal - very comforting.
Bought my oil pressure sender from Mazdaformance (http://www.mazdaformance.com) for $71 - p.n. N3A1-14-820. Heard Mazdacomp was cheaper.
Just adding my 2 cents.
