I have a 1997 5.9L 2500 dodge with 220000 miles on it. it ran perfect well yesterday i was driving down the road and it just shut down on me out of no where there was oil leaking onto the ground it wasn’t a lot but looked like enough and it looked like it was coming from my driver side when i checked my dipstick it was barely below safe but i filled it up 2 days ago i wasn’t overheating i cant remember what my oil pressure was at but this has never happened before any ideas what this could be

A 23 year old truck just doin’ its thing lol. Only way to see is to get under there and check it out. Could be any number of things on the driver side.

A high pressure oil pump?? The factory oil pump is located on the front of the engine inside the gear case on the passenger side. What modifications do you have on this engine?

For the starting issue, check your idle RPM. I believe an auto trans. should be somewhere around 800 RPM at idle, in gear, with AC on.

Back to the oil thing, if it’s bone stock, then it can certainly be a bad gasket/seal. Get under the truck and clean it up very good. Then turn the truck on and see whatcha got.

If you’ve been hard on it lately (high RPMS for an extended period of time), you may have just puked some oil out the breather tube which comes down near the starter and the block. Nothing you can do there. Now, if it’s puking oil from that tube at idle, then you may have a nice little project on your hands.

And then it dies? Definitely check your idle. See if you can manually hold your RPM at that 800 mark. If you can, then your idle screw on the back of your IP needs to be adjusted.

The oil is a ?? but I have had some strange thing happen on my 97 when the fuel filter stops working properly.
Are you sure its oil and not brake or steering fluid? I would check oil pan gasket and filler tube entry.

Until you get under and take a look after it’s been clean, you’ll never know. We can’t tell you from the other end of a phone/computer screen. Possibilities could include, but not limited to (on the driver side): tappet cover gasket, LP, IP, valve cover gasket, oil pan gasket, vacuum pump/power steering pump.

Like I said, it’s a 23 year old truck. If you’re blowing it out of the vent tube, then you’re piston rings are shot.

Which pump? The one on the side of the block, or the injection pump mounted to the gear case?

The one on the side of the block is your lift pump. That’s a relatively easy/cheap replacement. Just don’t get a cheap one. Geno’s garage and Power Driven Diesel would be solid sources for a lift pump.

I think he’s talking about the lift pump. Tops, that should be 200 bucks. I would do PDD because their company started by only doing 12 valve performance parts. Hell, for the past three years of UC see, they finished top three running a mechanically injected truck. I’ll give them my money lol

So which pump blew?
The lift pump, looks like this.
909169


Or the Injection pump?? Looks like this.

909170


Both photos curiosity of PDD website.

If its the lift pump, then that's a relativity easy and cheap fix. If its the injection pump, well that is a lot ( like a whole lot) more expensive thing to replace.

If it shot through the pump, there is no rebuilding. Brutal man. This is the first I have ever heard of a spring shooting through a Bosch P7100 pump.
