DIY: Oil Pressure Gauge

ChrisSlicks · 11-08-2012, 12:02 PM

Same oil used as before?

Pressures below 3k rpms are about half of what you had before. Anyone know if the design of the oil pump would be such that it can partially fail and reduce oil pressure without a complete failure?

I get 85 to 90 psi under wot. And when cold starts. Only time I get down to 35psi is at idle.

Yeah, my pressures have been cut in half fairly suddenly. This afternoon I'm going to change the oil and filter to make sure the filter isn't clogged and in bypass. Not particularly interested in pulling the oil pan off. If the pressures aren't better, I'll drop her off at Nissan and let them sort it out given I still should be covered under the 5yr/60k mile powertrain warranty.

I've been using the same Redline oil as usual. No idea why things have changed abruptly. Top reasons for low oil pressure I've read are 1) oil filter in bypass, 2) clogged strainer in the oil pan pickup, 3) frothing due to air getting picked up with overfilled oil pan, 4) oil pump seals worn, and 5) the ominous bearing problems.

Dropped the car off a Nissan for a few days. They checked the oil pressures with their equipment and said all is fine. Looks like the AEM gauge transducer is starting to crap out.

That sucks, but better than a failing oil pump!

This is my installation:

A little update about Glowshift Gauge:

1) good thing, I discovered that it's possible to setup an audible warning in conjunction with the warning lamp!
2) bad thing, the two pushbuttons moves without a guide, so I must add a rubber adhesive under it to avoid Rattle in the instrument...

too hard for me to do so...awesome

You're saying the vibration causes the buttons to be depressed and go into programming modes on the gauge?

flashgordon · 07-14-2013, 10:44 AM

No, no.....
The vibrations cause rattle during driving.
Placing a little piece of soft rubber under the buttons stops the rattle.
