I just brought my new babie home last nite and so far I love it. My only question is conserning the oil presure. I traded a 98.5 24 valve for this and on the old truck I was seeing reasonably high oil preasures at idle. Now with this new one it drops clear down to the bottome mark in the normal range at idle. Is this normal? I hope so because the truck only has 120 miles on it. It is just lower than I am used to seeing. Otherwise this thing is flawles. I absolutly love it. None of the noises people where complaining abought.

 

When my truck is at normal operating temperature, the oil pressure will be just above the bottom mark (~25psi). If the truck does idling when it is hot and gets to 195-200, the oil pressure will drop to 20psi. It maintains itself at about 45 when off idle.
Good luck with the new baby!

 

Congrats on the new ride.
check the tire pressure. A few of us had them delivered with about 40-45 psi --pretty low.

good luck and have fun driving.

 

My 03 does the same as yours. I considered it to be normal. When it drops to zero and the engine is still running, then I will let it bother me. FWIW, a mechanical OP guage installed in one of the ports on top of the oil filter housing will likely be more accurate than the dash guage.

 

I'm new to this site, I just bought my first diesel on 3-20-04 and I will probably have several questions in the future. I bought a 2004 2500 quad cab Dodge with the six speed tranny, and I love it!! Anyway I was just checking the site out.

 

I have some bad news for you. Your oil pressure guage is nothing more than a fancy idiot light. The computer reads the oil pressure as a pass/fail analysis. If the pressure "passes" the computer "runs" your guage to "match customer expectations."
The only time your oil pressure guage is 100% accurate is when it reads zero. If the guage reads above zero it is the computer trying to convince you that everything is all right, but the indicated pressure is in no way linked to a sending unit in the traditional sense.

When they came out with this "feature" there was a lot of discussion about it on this board. Dodge is not alone, any of your recent Ford Pickups have this same great "feature."

 

Even it its reading zero, it may not be 100% accurate. The pressure could be 7 psi and the gauge will read zero.

None of the big 3 have a real oil pressure sensor. Cummins was the last to switch because no one makes one that will last for the durability schedules required for certification. High warranty killed the one on the Dodge.

You could make a million bucks if you could make one.

 

That sucks. Looks like if I ever get gauges I will use on of them for a real oil presure gauge. Now that I dont need a trans temp gauge with the manual it will open up a spot on a 3 place gauge cluster. The next question is do they make a oil presure gauge and sender that will work for this aplication?

 

My bad, you are absolutely correct.
