Default RUNNING w/ failed OIL PRESSURE SENDING UNIT

There has been a lot of discussions about a malfunctioning OP sending unit but no one had bothered to ask or know if it is safe to run the car with failed OP sender assuming that it is only this sensor that is out of shape... input anyone?

It causes zero issues in and of itself.....only potential issues with you not finding out about an oil pressure problem soon enough. Honestly, by the time the oil pressure gauge records a problem its probably already too late but could potentially save you a costlier repair if you were alerted sooner.

The other reality is if your just street driving.....even aggressively (and you know your not low on oil), these engines are extremely reliable in that department....there is only a minuscule chance you will experience any issues related to oil pressure and its even less likely with an OEM shortblock.

Just my opinion....not suggesting you never get it handled....just sharing its not the end of the world if you don't do it tomorrow or next week even.

Due to trying to find the right parts to repair it "correctly" and partly to my laziness, my wife drove her car for a couple of months with a bad OP sending unit

We can talk forever about whether or not you need to monitor your oil pressure (I happen to think you should) but certainly we can agree an oil leak is not a good thing to ignore. Once the sensor has failed it is only a matter of time until it will start to leak oil down the back of the engine. The sad part is by the time you are able to notice the leak, the engine will be soaked. So I say, fix it as soon as you can. No, life as we know it on planet earth will not end if you don't.

Guys, the C5 has an low oil monitor, it goes on if you are one quart low on oil. So, you will be protected from low oil level even with a bad oil pressure gauge.

Again, I am not suggesting you don't need to monitor oil pressure . . . I fixed my sensor.

I drove a car for 8 years with no oil pressure sensor and it didnt bother me in the least. If my Vette lost it I wouldnt replace it either and it wouldnt bother me at all. I cant even think of the last time I even looked at my oil pressure gauge on the Vette while driving.
My daughters light is flickering on her car and I checked the sensor and its leaking some oil through it and shorting it so I just pulled the wire off cause the sensor is a PITA to get to and I didnt have time to change it on our visit to her. I told her dont worry about it as its not a problem unless you start to see a big oil spot on the ground on your driveway.

2+ years and over 20K miles on my aluminum replacement sending unit.
I drove over a month before I could get at it.

Surely you MUST be mistaken because I have read aluminum sensors will last no more than 30 seconds. If it's on the intewebs it must be true!

Mine leaked on the back of the engine after it failed. I have no clue how long it was out as I bought it like that. It was a mess and started to leak on the exhaust.

Mine started leaking down the back of the engine, replaced about 3 years ago and no issues since still working fine.

Problem is keeping the car nice. First you have one minor unfixed problem, then another, then another, and finally you wake up one morning and realize that your beautiful vette is approaching pos status. So if it breaks, fix it now.

I've recently fixed: tear in leather seat, scratch on side, leaky wheel rim, pressure sender, new tires, oil pressure sender, etc.. Plus god knows how much time cleaning, waxing, and fiddling with it.

Mine is well-kempt... and in A-1. Drive it everyday to work, 4 days a week job; but I'm only 2.3 miles away from my work- 40MPH limit with two points of school zone. LMAO figure that out. Change oil and filter every 3k miles. Diligently following recommended services.
Have read a lot of arguments about "aluminum and brass" and now undecided which one to get. I checked as suggested in other threads to confirm if culprit is really the sending
unit by just turning the ignition key on without running the engine. Lo and behold reading is pegged.
NOW - that malfunctioning unit therefore is not giving me the right and actual pressure of the oil.
But then again you folks are correct I NEED to have it taken care of. Actually surfing local stores now.

If you relocate the sensor I really don't think you need to worry about which, brass or aluminum you use. Changing becomes a less than 5 minute job.
