Safe travels!!!!!!!!!!!!

If it's the sensor, I recommend a slick upgrade Leeann and I found. The new Dodge vehicles use a dual oil pressure sensor that drives both a gauge and an idiot light. Two kinds of warning, double the safeguard against engine damage.

Leeann should have all the part numbers, including a source for an OEM pigtail to fit the newer sensor. (I had the info but lost it when I deleted all my browser bookmarks ... )

Ummm....I might just have that info at home somewhere [emoticon]

It is pretty slick, though. We wired a large, ultrabright red LED to the idiot light wire and mounted it above the oil pressure gauge - you cannot miss it. I got both parts from my local parts house, but I'm pretty sure you can get the pigtail from partsamerica.com (Advance Auto, etc).

Go get 'em, Trish! Good luck and safe travels [emoticon]

Thanks all for the gas tank info. Also reading the vin # discussion I realize mine is the f30 chassis as well. I will start looking for a tank that will fit this version. I think this rig sat for 3 or more years with very little fuel in it so the rusting inside to out is most likely culprit. (We have a very dry climate so outside moisture usually not a problem.) Of course thats also why it was only 400 bucks. Get what you pay for... lol thanks again ... Al

I don't think anyones dying statement ever contained the words "I wish I had spent more time in the office", so lets go somewhere!

Damn, Ce! You nearly took out my eye! [emoticon]

I sure didn't expect that! [emoticon]

Well...since there was no thumbs up smiley!!!!

Im off to sand the floor and try to fix my oil press gge.
Floor is rustier than I had hoped.

It would be cool to find new seats to put in...

Woohoooooo! I actually used my brain when Griff and I were discussing the oil pressure sender/idiot light, and copied his post into a document. So here 'tis, in its entirety:

Are you interested in converting to the dual gauge/light oil pressure sensor? I have the part numbers and am planning on putting it in my motorhomes -- the (idiot) light makes sure the driver notices a dangerous drop in oil pressure. Streetrodders, etc., used a bunch of plumbing to mount both gauge and light sensors on an engine. Manufacturers started using the combined sensors in the '90s and they eliminate the Rube Goldberg plumbing setups.

Here's a reprint of the article: http://www.allpar.com/history/mopar/electrical2.html

The article says they can't find the pigtail for the sensor but I tracked it down to a Parts America number ...

Like the article says, the sensor's OEM number is 53030493. NAPA's website shows two part numbers for replacements (http://www.napaonline.com//MasterPages/N........ster.aspx?PageId=430&OEMPartNum=53030493) -- ECH OP6670 at $24.99 and MPE OP6670SB at $19.99. (Different manufacturers for the same part ... ECH and MPE are NAPA codes for manufacturers.)

The Parts America (Schmuck's, Checker, Kragen, and Advance Auto) part number is PS233 at $29.99 each (http://www.partsamerica.com/ProductDetail.aspx?mfrcode=SMP&mfrpartnumber=PS233) -- be careful, that part number shows up a two very different items if you do a search on the number.

The Parts America part number for the pigtail is S727 at $26.99 each (http://www.partsamerica.com/ProductDetail.aspx?mfrcode=SMP&mfrpartnumber=PS233) -- again, be careful because a search on their website yields four different items.

Here's what Leeann and I have been talking about.

The wiring for older vehicles is one of these two:

The newer vehicles use this wiring:

The newer sensor basically combines the two older-style sensors into one package, with no real changes in the gauge and idiot light circuits.

The newer set-up eliminates the disadvantages of each individual set-up. In the older set-ups, gauges provide early warning of potential problems -- provided you notice the changes. Idiot lights catch your attention but usually don't come on until things reach a crisis.

Now, if only I could find a dual water temperature sensor ...

OK ya all, This talk about oil pressure gauges has me curious as to what my oil pressure should be. The unit (sensor) was leaking when I bought this Chinook, so I had it replaced, and the pressure is reading like 65-70 on tha gauge.. [emoticon]

I hate bothering you people on these things, but then you all seem to enjoy it so much... [emoticon]

Until I find a repair manual for this rig, you people are my best resource.

Now I know what it is, maybe I can find one.......Thanks Guys and Girls. [emoticon]

Assuming the sensor is working properly, there's not excessive resistance on the wire between the sensor and the gauge, and the gauge is reading correctly ... That sounds good. (Almost all automotive gauges are approximate ... the only way to know the true reading is to use a calibrated test gauge.)

Actually, that sounds very good ... that's the kind of reading I'd expect from a new or freshly rebuilt engine. In fact, if the reading was much higher, I'd be concerned about too much pressure.

Are you using 10W40 oil? Thicker oil will cause the a higher pressure reading. If you are using 10W40, you might want to try 10W30. Thinner oil will probably increase your power and economy slightly by decreasing the amount of effort required to push the thicker oil through the engine. (Here in Fairbanks, in the winter, 10W40 actually gets thick enough to keep an engine from starting.)

Read the www.allpar.com article listed above by Leeann. The article says Mopar OEM idiot light sensors don't trigger until the pressure drops to 8 psi and mentions aftermartket sensors as being better because most trigger when the pressure falls below 20 psi. (8 psi is waaaaay too low ... by the time the light comes on, you're on the edge of engine seizure ... 20 psi cutoff gives you time to find a safe place to park, shut down the engine, and find out what's wrong.)

BTW - Richard Ehrenberg (the author of the article) has been around Mopars for a long time, knows them inside out, and is very well respected ... I take his statements and opinions as gospel.
