What is your OIL PSI @ IDLE

GTS · Post by **GTS** » Tue Sep 19, 2006 6:39 pm

Well lately i've been hearing quite a bit of knocking and pinging noise from the engine. Now it could be one of two things.

1. Bad 87 Ocatane Gas (Shell or FJ)
2. Worn pistons and excesive knock.

when the engine is under load sometimes you can hear it very clearly. At the top gear if i step on the gas i can hear it ver well.

My Oil PSI at Idle is 20PSI does that sound about right.

Is it 20psi at warm or cold? I can let you know tomorrow what mine is at cold and warm when I'm in it for 6 hours lol

Well mine at cold i think is around 30PSI and when the car warms up the oil gets thinner I guess and it drops to ~20PSI.

It used to hold ~60PSI at highway speed ~3000RPM and now it seems like its around 50ish. So i wonder if the motor is getting worn out and I am hearing the piston slap more and more or if its just a bad gas that makes the knocking noise.

Reports online look to be

Cold Idle: 50 psi
Cold 3000 RPM: 80 psi
Warm idle: 25 psi
Warm 3000 rpm: 50 psi

Last I looked mine was at that, I'll doubt check it tomorrow. I just look at my gauge now and recognize where it's usually is and dont' really take note of the actual PSI.

20lbs at warm idle is more than fine.

Has it been getting colder in Chicago lately? I know it's gotten colder up here again and my car's back to the same old cold neon clickity clack again.

Damn Cold 3000RPM is at 80PSI holy cow I've never seen my gauge past 60 or 65. Wow my engine must be worn out then or the freaking gauge is messed up.

I think I read somewhere that the oil system has a pressure relief valve that opens at 60PSI and thats why I figured my gauge reading 60 should be alright.

BTW what Oil are you guys running. I am on MOBIL 1 5W30 every 5000miles.

Ohhh man I get that when it gets cooler on every cold start up. This morning it was around 50 and i heard it it was light but i can tell its there.

I will try some 93 Gas tomorrow and see if the ticking is still there and if its not then I will not its not the motor however if it is still there then i guess its just a bad piston slap. Hmmm I may have to look into an SRT swap or something.

First impressions I filled up with some 93 Gas this morning and I am not sure yet but the ticking seems to be gone so my conclusion so far is shell sells very bad gas. I've never had it detonate that bad. So no more shell fo me.

Idle:

Approx 3000RPM:

Mine oil psi did the same thing then my oil sender took a poo. It was reading pretty low, then all the sudden crusing at 3,000 rpms was at 70 or 80, then my gauge started to cut in and out, went to start it the next morning and my gauge no longer worked. Now I have a mechanical oil psi gauge and braided line waiting to be installed

Cant help you on the denation thing though.

ricer w/ the ricer gauge lol

u shoulda gotten the mechical cuz it s wayyyyyyyyyyy much more accurate.

engine cold cold 75psi @ idle, engine warm 25psi @ idle

That's what mine does.... Im only a 35k though

cas. 5w30 every 1500 miles

Some of us don't want a potential hydraulic leak inside our cars...

I've been around mechanical pressure gauges all my life and have never seen a drop of leaking fluid. Well just once but that was because my buddy used white teflon tape instead of yellow.

Oh thats true. Yellow FTW!!! haha Yeah pops has been building drag cars and hot rods since before I was a twitch in his wang. He never had a problem either.
Where I have had problems is at work on 900KW Waukesha generators and 350KW Caterpillars...I've lost two hydraulic guages on their monitoring panels and that gets really messy inside a control room...not good at all...
I whole heartedly agree with the "better" readings from hydraulics though they are WAY more precise than an ohm reading from an electrical unit.
Generally speaking though, on a NEON, we are looking for a complete failure so we can shut the car down an save our 2.0's. Anything below 25psi and my shit is parked. Anything above 75 psi and my rev limiter has prolly failed and I'm goin' for broke trying to beat somebody at the track.....haha

cold idle : 60 psi
cold 3000rpm : 80 psi
warm idle : 30 psi
warm 3000rpm : 70 psi
