low oil pressure chime always comes on at idle

Since the truck had about 90K miles on it the low oil pressure gauge and chime goes off at 700RPM (Idle). I've had the sensor replaced 3 times, about two weeks later it does it again. Iv'e had the oil pressure check by skilled Dodge mechanics and they say ay 700RMP it is slightly low but within parameters of normal. They reset the Computer and again about two weeks later it does it again. The motor threw a rod at 98K and Dodge replaced the 5.9 Magnum with another 5.9 Magnum that did the same thing?? The new motor was slower and ate more gas as well, I sent it back 10 times and gave up. The rest of the drivetrain had been replaced between 75K and 90K everything except the front suspension which just failed completely this year, "All of it!!!!" Rack and P and all other parts and bushings. (POS!) the engine now has about 40K on it and it still has the same low oil chime! My girl friend hates it and wants me to dump my New-Old truck. The whole drive train including radiators, HVAC, Heater cores and u-joints are all practically new. The low oil chime is driving me and all of our passengers nuts! I heard on your forum a guy took the speaker out, then he got a CEL? I heard another guy put silicone in it? that is a good idea! Can you show me where to just drill a hole and use a syringe to fill it? I was hoping for a resistor or battery hack? I've heard of many other people having the same issue I am but they never found a cure, they sole the truck. Apparently all the V8's from 98-2007 have this issue? I have 3 Dodges, cant wait to get Toyotas.

Same as the other complaints. Engine pressure suddenly dropped but did not hear any valve chatter. Took it to a garage and the mechanic thought it might be electrical. They didn't charge me for checking. I let my son use the truck when I was out of the country in January 2010. He was driving it in a rural area when the oil pressure dropped. He thought the problem was electrical as that's what the mechanic told him. Unfortunately, he kept driving. After about 10 miles, he heard engine chatter from the valves but it was too late and the engine spun a bearing. He had the vehicle towed back to the shop. The ace mechanic then decided to check the oil pressure with a meter and found it was only putting out 5 lbs. of oil pressure.

This is clearly an engineering flaw by Dodge. This engine was well-maintained, not burning oil and was never abused. I have never had a vehicle that failed so prematurely as this Dakota. I have purchased Dodge and Chrysler dating back 40 years. This will be my last Dodge or Chrysler vehicle. I don't consider them a reliable product anymore.

Needless to say, I don't use Ace the mechanic or his employer anymore either. I'm pulling the engine this summer and rebuilding it myself. I estimate the cost will be about $800 to $1000 for the new parts, new oil pump, machine shop work, and my neighbor's time to help. A ten year old truck even in excellent condition, isn't worth putting in any more money than that on an engine overhaul. If I weren't able to do the work myself, the truck would have been sold for the best price this past spring or hauled off to the bone yard.

lost oil pressure driving down road hauled truck home and changed oil it was full of sludge new oil was ok for 3day then lost oil pressure again dragged it back home again and drained oil again and it didn't look to bad but my oil pickup screen was obviously plugged so I went and got 5 gal of diesel fuel "MY STEP DAD SHOWED MY THIS TRICK YEARS AGO"poured all 5 gal in oil fill and immediately drained diesel fuel it flushes the engine and screen very well. it comes out "FAST" do not put in- until oil is drained- and do not let it set in motor drain right away- i made that mistake before"MAKES ENGINE SMOKE TERRIBLY FOR APPROX.FOR 30MIN."once i drained diesel fuel out i put fully synthetic oil in and mobil1 oil filter been ok so far. have 233,000 miles now and have changed oil SYNTHETIC" every 15,000 miles since my sludge problem 97,000 miles ago.synthetic oil is better in my opinion. it doesn't seem to sludge up and cheaper because you only need to change every 15,000 instead of every 3,000 miles. I also like the mobil1 oil filter there about $14 but they do not have traditional paper in them which can break down within 15,000 mi oil change and you could end up with paper floating around "FROM A CHEAP PAPER OIL FILTER" in your oil"THAT'S NOT GOOD" tha'ts worse than sludge. also they hold 30% more contaminants before they would have the possibility of plugging up and blocking off oil pressure.I only had to do the diesel trick once on my dodge but the last truck I done that to years ago I did it once and it was ok for a while then lost oil pressure again. so i flushed it 1 more time and it was ok the rest of its days.

I took the truck in because the oil pressure had dropped, due to check valve sticking gauge was acting up. The mechanic did a pressure test and replaced the gauge. A week later the engine starting acting up and I shut down immediately but it did no good. It is now tapping and the mechanic says it need a new engine or I need to trade it in. An engine for this model and year is at premium price because this problem seems to be common with this year and engines are in short supply. My mechanic found a few at approx $5500.00. I can almost get a new truck for that amount.
