Oil Pressure at 25 PSI while idling.

[moparracing]

Heres a comparison


My rc drops to 25 during idle @ 200 deg F (No fan mod yet)
My Qc drops to 35 during idle @ 175 Deg F


At higher rpms >50 psi

sounds about right........

Naaaawww...worse...they caught me practicing my 1/4 mile times in a 25 MPH zone.

But I got my priviledges back and we is straight!

Thanx for the input guys! I appreciate it!:rock:

Dude!!!!!!! Growing up on army bases I learned real fast you never speed......ever!!! The MP's would give you a ticket for just a few mph over the limit. They were completly unforgiving!!

I got a ticket on Ft. Bragg years ago for flashing my lights at on-coming cars to warn them of a radar trap...the ticket was for impeding justice!

FSM info on engine oil pressure for 8.3L engine:

CHECKING ENGINE OIL PRESSURE
1. Remove oil pressure sensor (Refer to 9 - ENGINE/LUBRICATION/OIL PRESSURE SENSOR - REMOVAL).
2. Install oil pressure gauge.
3. Warm engine at high idle until thermostat opens.
CAUTION: If oil pressure is 0 at idle, Do Not Run engine at 3000 RPM.
4. Oil pressure should be 68.9 kPa (10 psi) at idle or 310 - 517 kPa (45 - 75 psi) at 3000 RPM.
5. If oil pressure is 0 at idle, shut off engine. Check for a clogged oil pick-up screen or a pressure relief valve stuck
open.

There not much nicer on an AF Base

Krazy u still on the island? if so ask what weight they used bro, if its real dang hot, go with something besides 0w anything

but yeah bro 25psi is good at idle

I was always told by an old engine builder buddy of mine that you should always have 10 psi of pressure per every 1000 rpm. Of course he never built a Viper V-10, only V-8 GM's. As for speeding, don't get caught here in Japan by the base MP's or the local Japanese police. They are cancelling people's orders, suspending their drivers license for 1 year, making you sell your car and kicking them out of the country. Of course you know where most of them are getting stationed... the wonderful Iraqi desert.

 

[KRAZYSRT10]

As far as I know they are using the factory recommended stuff, I dont get my hands dirty with the car oil. I Get enough of the -23699 and -83282 all over them.

And for the speeding thing....WHERE WERE YOU GUYS 8 MONTHS AGO WHEN I GOT BUSTED!!!

I finally got my ticket appealed on the 4th of August...so I got off the hook about 5 months early!

On the upside...only 8500 miles on my beauty....most of the nicks and scratches have been caused by the dealership, the nieghbor and the lawn guys!

mine drops to 25 while at idle

That's odd that we have such a variance of oil pressure readings. Mine sits at about 50 psi at idle and jumps up when i rev it.

Some causes of low oil pressure that I have experienced in my race car:

#1 - water in the oil (blown head gasket)
#2 - worn rod bearings (low oil pressure happens before any other noticeable knocking happens.
#3 - clogged oil pickup (usually my fault by getting RTV or something like that in the oil)
#4 - bad oil pressure gauge. This has actually never happened to me but it's a possibility

Mine never goes below 50 at idle either. However, your #4 is why I prefer mechanical gauges over electric. If my stocker ever dies, that is what it will get replaced with.

I use a mechanical gauge in my race car too. it's so freaken fast to react too. I love it!

the only thing is you have to run a line into the drivers compartment that (if it leaks) could spray hot oil on the nice leather interior!

After doing a risk analysis, the benefit of having an accurate oil pressure gauge outweighs the risk of oil leaking in the cab. :laugh: The only gauge I would consider installing that is electric is fuel pressure, but if you purchase an isolator you can go with a mechanical version of that too.
