Oil Pressure Gauge issue

[grimm]

Thanks for the input guys. I'll post an update when the oil is changed, the filter replaced, and everything at proper levels.

Sorry to bring back my old thread, but I figured it would be good for someone else to know if they see the same thing. My oil pump is fine. The sending unit ended up being okay as well. I change the oil and filter and made sure I was at the proper levels and the problem has stopped. As it would turn out, I was just a little low on oil. If your oil pressure gauge dances around, try the simple solution first. It may not be as big of a deal as you think.

I have the same but opposite it redlines and even further as seen in the image I posted on the temp gauge thread. I have done mulitple oil changes and no change i have not check with a manual guage yet but when I get free time I will try that. HOPE IT ISN't the pump.

Hmm, that one almost seems like a faulty gauge or sending unit, but I can't be 100 percent sure. Manually check you pressure to see if its within spec. If so, then you're alright and just have a false reading.

What is the specs

curb idle and 3000 rpm???

Anyone have an idea what the psi should be at those rpms?

I'm not 100 percent sure if this applies to the older TBIs, but I would imagine so. According to my manual :

-Cold start up should be around 45-60 psi, in all rpm ranges
-After warm, you should be seeing a minimum pressure of 18-22psi at idle.
-Under load should be around 45-60 psi, once again
-Cruising should warrant about 40-45 psi.

If you check you pressure manually and you get roughly those results, you should be okay. Maybe someone with a pre-96 truck will chime in with more info, just in case the specs are different for the TBIs (I don't see why they would be though)

Cool THANKS!!! at least it is a guide line to follow.

In my 95 my guage cluster did start to go and my OP was the first guage to act badly...in my case it was either reading correctly or too high.

The guage cluster didn't seem to surprise the part guy at my gm store...rather than drop 500 on a new one I just put in a mechanical guage.

After a while my volt meter began to read low as well.
