oil pressure sending unit? how important?
Is the oil pressure sending unit only really going to mask if there is an actual issue with oil pressure down the line, or will it cause immediate short term issues, and tell the computer to send too much or too little oil in the short term?
Thanks
Thanks

HUH? You're kidding right?
But, just in case you aren't.......the purpose of the sending unit is to MONITOR and REPORT oil pressure in the engine. It does no more than that. This info is invaluable, cause if you were to continue to drive with no oil pressure, you seize the engine. If you didn't know there was no pressure, you wouldn't know not to shut the car down.
Same goes for too high a pressure. Shows you there is a blockage or malfunction of the oiling system, so you can shut if down before doing catostrophic damage.

Correct, what im saying is though, i have seen on other forums several people say its simply just for your eye, for you see where the oil pressure is, but that the computer will continue to send proper oil, is this correct or not? Others have driven with it not working for thousands of miles with no problems.
Just getting other opinions

If just the sending unit is bad then yes the engine will continue to run with proper pressure, but how will you know that if you drive with a bad sending unit?

If you loose oil pressure and keep driving it can cost you a new engine, $5,000-7,000.
Here are some things that can (and have happened).
Oil Change people don't put drain plug in tight, it falls out and you loose oil.
Oil filter isn't tight enough, it comes loose and you loose oil.
You drive over piece of metal, it puts a hole in the oil pan, you loose oil.
Oil pump malfunctions, you loose oil pressure.

Although...
Something that I just noticed yesterday....
Yet another item to add to my Spring Maintainence of my baby....
My oil pressure gauge is- [while running, always maxed out.....turn engine off, gauge back to zero....]
Of course, this immediately made me a bit worried....
Although, my buddy @ the "Stealership" said it's fairly common, as long as you're not experincing any difference in driving, losing oil, etc....then odds are it's just the sensor....
Well, I am not ABOUT TO RISK driving around & ruining my engine....
So, I'm sure plenty of others have had this same issue, since I just did a search on the topic....
Only question is....
Any help/input/FYI's etc as far as it goes concerning replacing the sensor,,,.....from my knowledge/research/etc...this is no small endeavor......it requires yanking the intake manifold, etc.....
Damn.....
Also, anybody have any input/or a passenger side front headlight motor up for grabs/sale/trade?
I might as well get both these issues dealt with simulaneously....I hate my car being out of my possession-[or eyesight for that matter......]
Here we go....Oh well...
Thanks in advance fellas...

It seems from what I've heard & the small bit of research I've done, this is not going to like swapping out a battery or alternator......
Hmmmm....oh well.....any others have any first-hand experience with this "exciting endeavor" I'm going to have to handle asap......hell, it's march, but might as well knock it out now while its in the 60's here as opposed to waiting another month or 2 & it being 95-105 everyday for 7 months......
<----------[Staying Optomistic!] No big deal really.....owned her for almost 4 years now & only small things have needed fixing.....might as well begin drafting a buddy or 2-3, it's always more fun to work on a vette with a couple buds...[If I offered to buy the beer they'd prob. be here in under 30 min. - HA, ha.....]

I didn't want to do any cutting, so I had the dealer fix it. If I remember, it was about $125.00. I know...I got screwed, but what the hell!
By the way, that was about a year ago and it went out AGAIN about 6 months ago. This time it was free....still under warranty.
You need to make sure you do NOT over-torque them when installing.

$125. isnt bad. remember the dealer usually warranties the part they install for life but labor costs you each time.

I replaced my oil pressure sending unit in about 45 minutes last weekend. I didn't want to pull the intake, so I cut the access hole.
Just get your car fixed. You'll be VERY glad you did.

It's important to know you have oil pressure. Replacement is easy by cutting a hole in the cowl. Pull the wiper blades, pull 5 push pins to remove the lower windshield trim. Cut the hole ( I used a hole saw) directly over the sending unit. Replace the "cut-out" piece and tape over it with metal hvac tape. Took maybe 1/2 hr. Replacing it in the future if necessary would be much quicker.

What did you use to cut the hole?
Is that hose tough to get out of the way?
