Title: Lost oil pressure for a few seconds on start-up
Post by: cj7ox on April 19, 2022, 03:46:32 PM: So, had an issue this morning (2006 Ram 3500 Cummins). Outside temp was 46*. Started up to come to work, and after a few seconds the check gauges light came on. Oil pressure gauge dropped to 0. I shut it off. Started it back up, paying attention to the gauge. Pressure came up, then slowly began to drop. I bumped the throttle, and it went back to normal. Engine sounded smooth, no unusual noises. I drove it in to work with no other issues, but continued to pay attention to it. Through my running to various appointments today, everything was normal. Anyone have any thoughts what this is?

Post by: wilsonphil on April 19, 2022, 04:59:30 PM: I'm sure you did, but check oil, attach mechanical gauge, my guess you have a bad oil pressure unit.

I think the 06 are still on the left side of the engine, pretty easy to get too and change.

Post by: KensAuto on April 19, 2022, 07:08:00 PM: Sounds like the pressure release stuck initially. Is it fresh oil?
I tend to see that on cars after a recent oil change.
Edit: that's if it's not the sending unit.

Oil pressure=blood pressure

You need to know if the gauge is accurate, like Phil basically said.

Yeah. Time and only having one vehicle here are my enemies right now.

Ditto
We did that with the pre-ranger's silverado.
It's how we confirmed the oil pressure gage was accurate and the oil pump was failing.
We saved the engine and only had to drive around with that silly nylon hose flappin' in the breeze!

Post by: cj7ox on April 21, 2022, 02:41:29 PM: Well, I believe I discovered the problem. My dumb@$$ checked the oil, and it didn't register on the dipstick. Added a couple quarts, and drove it to the oil change place. No sign of oil leaks on the truck, and no spotting on the ground. I guess the old girl burned up a bit when I was driving back from Co Springs a few weeks ago. I got stuck in a snow storm east of the springs, and sat for a long time idling while the pulled a semi out of a ditch. Ended up being a 30 hour drive (continuous, minus fuel stops) to get back to Columbus, GA. Only thing I can think of. I'll be checking it regular to see if it goes down. I'm a bit of a :knucklehead: sometimes.

Well, you are a tanker... ;-)
Title: Re: Lost oil pressure for a few seconds on start-up
Post by: cj7ox on April 22, 2022, 11:23:23 AM: Yeah, well. I think all of us have succumbed, at some point to the thought, "It couldn't possibly be that!" LOL! My mind went right to "this must be a complex problem" when I should have just stuck to the basics.

And Tex, it's been quite a while since I worked with explosives. 70+ ton steel and DU battlewagons, are another story entirely! LOL

Post by: wilsonphil on April 22, 2022, 06:29:07 PM: Hold on now,

Dipstick operation is a very complex system to master, now you have a better foundation to start from.

Just look Ken had you rebuilding the engine, and TRN had you calling engine shops to get labor quotes.

Dipsticks are tricky but it seems you might be on a positive trajectory to understanding the basics

Post by: cj7ox on April 25, 2022, 11:01:16 AM: You know, I did have to break out the manual to figure out how to operate the dipstick. It sent me to a youtube channel that had a man-bun wearing hippy tell me about all the benefits of joining the liberal movement. I then said, "To h3ll with that!", popped the hood, and grabbed hold of this stick thingy that said "OIL" on it! Would you believe that stick thingy actually has an area on it that says "SAFE LEVEL" and another that says "ADD OIL"? Who new? LOL

Checked the oil multiple times over the past few days, and it is solidly in the safe zone. I'll continue to keep an eye on it. Still no leaks or drips anywhere.

Oh, and as an ARMEE combat arms guy, my skin is quite think. I've enjoyed the comments on my stupidity. Keeps one humble! ;-)

You're good
Only one perfect man in all of history, and NO, he wasn't an Armee aviator!
Second
Give Kenneth all the information.
The man's an oracle.
He'll pray over it, or dance, or something, then mix up some smoke and contact the spirit of some long-dead Cummins mechanic, and just like that he will tell you to re-torque the left rear oil pan bolt and add two drops of alcohol to the air filter and next time use a left hand funnel to add oil (To correctly set the initial spin of the fluid) and boom! Just like that you'll be all fixed up
