Have had my 2000 C5 now for 6½ years. She has 76k on the odometer. I was out cruising through the Hocking Hills here in SE Ohio where I live on a beautiful day and happened to look over at my oil pressure gauge and it was pegged @ 80 psi. Went to the DIC and the oil pressure read 130 psi. Stopped and checked oil level and it was fine. Just changed oil at stealership about 45 days (500 miles) ago. Other readings:
Oil temp 203 F
Coolant temp 198 F
Tran Fluid 174 F
Battery 13.6 volts

Any thoughts? I am sure this is outside the normal operating limits. Potential causes? Drove another 7-8 miles home, very gently.

 

Very common issue. The Oil Pressure Sensor behind the intake manifold is bad. Just change it and you will be fine. There are hundreds of post on this very subject!!

 

Same thing just happened to mine Monday. The digital gauge reads 130psi. I'm odering a sending unit and 1-1/16" socket and doing it without removing the intake.

 

It's hard to believe you've been a member since 05 and haven't read about this. If you do a search on oil pressure sensor, you'll find at least three possible methods of replacing the sensor and there are even videos with the instructions. I bought a brass sensor at O'Reilly's for under 40 bucks. If you choose to use the remove the intake method, you can also add relocating the sensor so you can change it easier next time. If you take it to a dealer, you're talking around $400.

 

Kinda Harsh! Look at the OP's post record. Maybe been around a while but he is no heavy duty dude like us. Just the advice would have been better than the accompanying put down!


Just say'in,,,,,,,

 

HARSH? to say it's hard to believe something? I gave him some information and how to find the rest. If you think that was harsh, hang around and read some of the posts these guys give, specially if you're trying to buy or sell a car. I don't understand why something that is hard for ME to believe is a "put down" to the OP. I think you're just trying to stir up trouble.

 

Not at all, just didn't think your post needed the preface you chose. That is all,,,,,

 

That's ok, I didn't think your post helped him in any way. My post wasn't to you, about you, or even concern you. I'm sure he appreciates you defending him from my harsh put down. Hopefully, he was able to search for the options and get started on fixing the original problem, high oil pressure.

 

We are good Bro!

 

Thanks to all who provided constructive information on the issue I ran into last evening. I only had a short time to get online and appreciate those. I'll have some time later today to do further research and get the problem fixed.

Silverbullett00 - Thank you for your kind comments.

Perhaps if there were a little less arrogance and sarcasm on this forum, some of us would spend more time here.

Thanx!

 

I'm sorry that you thought my statement of MY belief that with literally thousands of posts about the oil pressure pegging on the forum and you being a long time member that you hadn't read anything about it to be either arrogant or sarcastic. It was merely a musing that you must not read many of the threads to have been around so long. Both you and Silverbullet seem to have overlooked the information I gave you about how to get the issue resolved. Duly noted, and in the future I will allow someone else to assist you. I don't want to offend any sensibilities. Maybe using search would be an option? Any way you read it, you still need a new oil pressure sensor.

 

Oil Pressure update. I now have #3 in my 99. I have changed it each time and searching for why they fail. My last one I may have found the basic cause.

I found the top plastic part of mine cracked due to the wire harness being very short putting pressure on the sending unit resulting in the crack.

I called local chevy for a new plug thinking I would buy a new plug and just cut/splice it in. The new plug was $65 at dealer and about $40 online.

I decided to cut my harness and splice in a 10" extension. I used what I call a western untion splice and soldered / shrink tubed the connections. Then for the installation I made sure I had a 3" loop of wire over the connector to act as stress relief. Now there is no pressure on the plastic part of the sending unit. Hopefully sending unit #3 will last longer. I did cut through the cowl for the 3" hole to attempt changing the unit w/o pulling the manifold. Just would not work out for me. I had to pull the manifold again. I have it to about 1 hr 30 min to pull and after clean up / new gaskets about 1 hr to install. Still a real PITA and NO fun.

 

Jimcork,

do you happen to have the part number for the electrical plug.

I am having the same issue.

Thanks

found it #12102747

 

The plug is $$.. $65 at the dealer and about $40 by mail. That is why I decided to cut and splice mine.

Google western union splice and see how I connected the extension. Also be sure to leave a loop of wire to take all stress off the sender. If you noticed when you unplugged the wire is VERY short and this does cause problems.

 

Lighten up Francis.

 

Another helpful post about "oil pressure", the question has been answered, let it lie.

 

When someone says, its hard to believe, what he is really saying is.. with the 3,642 post on this subject.. its hard to believe you did not do a search on this subject first... Now here is my point... Of the 15,000 plus private message help post Ive received over the last 10 plus years.. I had a guy ask me a similar question.. in private message... his excuse to me was that he was too lazy to do a search and after all is not that what " I " am here for? he didn't thank me or anything but almost demanded that I help him...

Point being, while many of us are here to help... This particular issue has been well discussed over the years. A search should be the first course of action when seeking help.. in this way you can get a consensus of opinion.

I have been harsh with many over the years and I know what harshness is...I also deal out harshness when I feel its necessary.... for someone to say I cant believe ... is hardly harshness... but then that just my opinion... I would call that tough love... more than harshness... maybe the next time the OP might do a search first... Its just a thought
With all my love
XXXOOO

I think the difference in ET's response and 65GGvert's response is painfully obvious. ET signs his posts with Love.....and.... hugs & kisses.

Take note 65GGvert......this is the way to a sensitive Corvette owners heart !!

 

Too many cry babies on here these days.

A car that's been out of production for 7 years-most things have been discussed already (some 1000's of times). You can typically look it up faster than posting a question and waiting for a response. It seems most can look things up for themselves-but they want other to do it for themselves because they are too lazy (or worse). Many won't even look in their owners manual for answers.

The stickys at the top are almost worthless to many posters-when they get too long, newbies don't want to read anything longer than a tweet so they post yet again about something that's been answered 1000's of times.

 

Why not just make a decision to :

1) chose to help
2) Remain silent

Why all the bickering. So what, everyone was a beginner once. I have searched for items and never found what I wanted and then had someone say search.

NUTS Either help or don't but make a decision and quit bickering.
