Greetings fellas.. I own a 2000 Dodge Ram Van 2500 that has been very reliable for the last 8 years.. Except for one thing; the oil pressure gauge keeps going to 0..
This happened about a year and a half ago and I was told it was the oil pump.. :mad: So I replaced it for around 2k.. NOW, its happening all over again!
So I called the mechanic that replaced the oil pump last time and he says "There is no way you have 2 bad oil pumps in 2 years." For what he charged me before, that seems fair because in this economy, it would be highly likely anyone would invite "a big job" rather than say "it cant be". Some are telling me a sensor (none have specified 'which') others are saying gaskets.. Calling all painters, plumbers, sparkys, anyone who has heard of this with Dodge Vans

My question is: Has anyone ever ran into this with any Dodge Van (similar to the make and model)?? This thing is driving me nuts because without my horse...I cant ride. If I cant ride...

I starve :thumbsup:

rings a bell

go to an autoparts store and install an aftermarket oil pressure gauge and sender then observe pressure via the new gauge. I've heard of senders going out in other vehicles (chevy in my case). You could have a compression test run on the cylinders, but being that van engines are difficult to access...the compressoin readings could give you an indication of poor oil issues.
hey thanx so you're saying go to autozone and ask for "aftermarket"? I assume because the price is better?
Then install gauge and sender (oil sending unit?) and that will tell me is the oil pump is the cause or something else right?
Is this the compression test itself or is that something different? You are very right about vans and access to engines.. Thats why Im trying to inform lyself as much as possible.. But I got to make a decision fast..
:sweatdrop:

Lo & Behold My 1997 Dodge 3500 with the 5.2 liter motor started doing this when I would stop for red lites, Etc. Could not figure it out why ??? The motor was really quiet & runs good. Well I was talking to My brother-in-law who has a lot of contacts about vehicles & he stated that there might be too much oil in it !! I told him I had been adding some and didn't know where it was going. He said he knew of someone with a Dodge with the similar problem & it had something to do with checking the oil with the dipstick that it was Screwy. So I checked it four or five times & found that I had too much Oil in it. I drained some out & my gauge didn't drop to zero anymore with the lite coming on !!!! Since then though, which has been about 5 months, the gauge will drop, but not that low, once in a great while but I don't worry about it. Hope this helps!!!!!!!!!!

wow interesting.. because this same thing happens to me when i DONT have enough oil in it...go figure.. I have actually gotten used to the gauge dropping at sudden stops when its time to change the oil..
But this time its different.. When I start up the gauge doesnt go up immediately.. instead i have to wait about 10 sec, then i hear a faint "zip" or zipping sound, then the gauge sets properly.. when I drive about 5 blocks it goes completely down to zero.. and stays there..
no knocking or ticking.. drives fine but dont wanna risk anything

Oil Pressure

Is the van a diesel or gas? I would have the compression checked. If the compression is good your oil pressure gauge may be malfunctioning. If your had oil pressure of 0, the car would not be able to drive. I think it is a sensor issue, especially if the oil pressure reading goes through the obd II

easy way out b/c it sounds as if dodge's may have an issue w/ OPS going bad-the easy out is that if you replace it w/ another factory style unit and it goes out again in a year you're in the same place as before...I would have more confidence in an aftermarket gauge.

just a thought...when I've inadvertantly run engines low on oil the valve train would become noiser b/c of lack of lubrication. If there is no oil lubricating the valves the engine WILL be louder than normal. You should be able to distiquish the difference in sound and note a problem w/ the guage working. As someone mentioned before in this thread, if the dipstick is not reading properly, maybe it's just low on oil (?)

well boys, the verdict came in... the motor is shot and thats that..
according to my mechanic it has something to do with the main band thats deep inside the engine and the only thing he can suggest is to replace the motor :mad:
so Im dead in the water.. nice meeting yall
guess i'll go get a job at home depot for $10p/h - oh yeah they piss test
maybe i'll go work for roto-rooter - oh yeah the run a background
maybe i'll check the local construction co. - damn, i dont speak spanish
oh well i'll just shoot myself - oh yeah, cant afford the bullets

i need a fifth of somethin..

The thing I’m wondering about… is that even though you have an oil pressure gauge, there should still be an idiot light in the instrument cluster for oil pressure.
You should see it come on when you turn the ignition to the on position or start the engine. It should then go out when the engine starts, if oil pressure is within spec.
Is the oil idiot light on the dash illuminated with the engine running?
If not, your engine would normally still have oil pressure regardless of what the gauge says.

The oil gauge on my ‘90 Dodge work truck with a 5.2 V8 TBI [318] also started dropping to zero as I drove about 7-years ago. The idiot light on the dash never came on, so I new it was either just the gauge, the oil pressure sending unit or wiring.
I replaced the sending unit and all was fine. I will be celebrating its 20th year of ownership in 2010.

Main Band??

I think he meant Main Bearings... If they are shot, you will lose oil pressure...

Usually takes 150k miles, an overheat, or low oil event to make them go bad.

When they get very bad, you will hear them knocking...

Throw some stp and sawdust in it:whistling...should get you to your new job at HD:laughing::laughing:j/k..........for awhile
