Oil pressure

Shorted Gauge Wiring

After reading about the oil pressure gauge really being a fancy on/off switch I decided to take a closer look at mine. I found that when I turn the key on with the engine off I had "normal" 65 lbs pressure. Did some looking and found that when the power steering pump was assembled at the factory they caught the wire to the oil sender and EOV steering under the pump and crushed it to the engine grounding it. Going in to the dealer tommorrow to fix. FYI for all of you to check yours. It would have shown normal pressure with no oil in it!!! Anyway, ordered the Auto Meter gauge today. If you reach down by behind the P/S pump and pull on the wire slightly it should have some give. If not, it may be pinched too. Of course if the gauge works with the engine off, that's a good sign it's shorted too.

My gauges work well. At idle, I get about 75 lbs. on my oil gauge, and almost 14 volts on my voltmeter. I can see the voltmeter drop a little under load.
 
No after market gauges, mine is all stock (so far) except for my K&N air filter.
 
Ross,
I'll bet your oil pressure indicates the same whether the car is hot or cold, idling or revved up. That ain't a real pressure gauge.
 
Not a real pressure gauge?! I think I'm about to get a lesson on gauges. What does the gauge measure if not true pressure? If the gauge isn't a real one, and I want to put in a real one, which ones are good, and will fit in the same space without any modifications? Also, how difficult will it be to install a real one without messing something up?

Do a search on "oil pressure," "gauge," or a combo of the two. The info is already out there on this board.
 
MMM2003,

Better check this out since the gauge should only read Zero pressure with ignition turned on. See previous post regarding a similiar members problems with this condition.

OK--after reading all of these posts, I called Auto meter and I'm going to order PN 4427 (a previous post said 4327, but the guy at Autometer and their website says 4427), and have a real pressure gauge. I have seen a previous post about installing the wiring, and about how you have to cut a connector and make some sort of adapter. This kind of has me scared, and I wonder if I'm going to get a good installation with a rigged up connection? Also, how do I get the original gauge out of the cluster without a pry bar and lots of scars left on the car? Are there any detailed instructions anywhere? I'm not incompetent with tools, but I don't want to mess up a new car, either mechanically or cosmetically. As usual, thanks guys. Ross

4327 is for the 2 1/16" diameter gauge. 4427 is for the 2 5/8" diameter gauge. You might want to measure your gauges.
 
Ross,
For detailed removal & replacement instructions just search these posts. The cluster just pulls loose. Detailed instructions are on here somewhere.

The stock gauge should read 0 when the key is on but engine not running. About 75 when the engine is running. It's just a fancy idiot light.
