how many here run a mech oil psi gauge

[ellis93]

I broke the OEM sender and replaced it with a Borg-warner unit from O'Reilly. Before with the old unit the gauge read half way,hot.....and 3/4,hot,running down the road. Now with the new one installed I'm seeing 1/4 hot and 1/2 running down the road.
This had me curious this morning so I screwed in a test gauge.....hot,idling....grand total of 35lbs and 60 rev'd up.

What I want to know is what's the pressures you all are seeing?

[skilletky]

when i had mine hooked up, i was seening 65 or 75 cold idle, 20 to 30 hot idle, and anywhere from 45 to 55 hot going down the road

[RCCUMMINS89]

Me too.....

I see 65-80 cold idle, 30-45 hot idle, and 55 going down the road.

[ellis93]

Good it's normal then.....I've just never seen it that low....ever

What's the chances of one getting it up some by dickin with the regulator?

[RCCUMMINS89]

It's plenty high enough for everything to get proper oil, I wouldn't mess with the regulator. (didn't know there was one)

I gained 10 psi of hot idle psi....when I changed my turbo. The new turbo, being tighter and therefore more restrictive gained me that much in oil pressure.

[ellis93]

Yep there's always a regulator in any oiling system,ours is in the oil filter housing.....as far as I'm seeing on the net. I've not looked into it hard yet.

Makes perfect sense on the turbo increasing oil psi. That's a pretty good bleed if those bushings aren't tight. Essentially it would be an open hole to puke psi thru.
I don't think I've problems there tho,everything still is tight,idk

[RCCUMMINS89]

My old turbo was still "normal" on shaft play, no in/out....didn't leak a drop.

But again, I don't see your oil psi being a problem. My 01 and 03 that I used to own both well under a 100k miles....they'd run 40 psi warm oil pressure and 50 running down the highway...hot idle would be 25.

[ellis93]

I'll probably let it be......it just bugs me

I need to focus on injection pump anyhow.

[stoneagemaxx]

I do and my psi is arkund 75 80 cold 35 45 warm

[Mckinney]

I checked it out in the original service manual and it states that the gauge should be 1/4 of the way at idle and at about 1/2 when under load. Just so you know

[dunes450r]

i've seen as low as 20 at hot idle. normally in the 30 range. and 80+ on cold mornings high idle

[moose5.9]

Both 5.9 cummins swaps i did had 65 psi cold idle, 35 warm idle, and about 40 ish driving, both mech. gauges. Both engines were 12v with ve pumps out of yard horses
