Just Bought Yesterday 2001 7.3 need help.

Hello all.. I just bought a 2001 F-350 crew cab dually 2wd Diesel with 670,000 Yes 670,000 miles on it. I bought the truck from a auction. When i bought the truck it had dead batteries and wasn't even sure if it ran but was told it did so i got it. Well i put new batteries in it and it started right up. Truck runs really ruff while cold and shakes the whole truck after it warms up it gets alittle better. But i am pretty sure that it has a bad injector or 2. No biggie there. So i drove it about 60 miles the way it is to check it out. It Drives really nice. But i got on it down the highway and all the sudden i lost oil pressure gauge and red oil light came on. So i pulled over checked it out not leaking or anything. Started it back up and listened no knocks or crazy noises. So i was wondering if the sending unit went out.. Then today i went out side and fired it up and it ran like crap for about 10 mins then got better. Once it got alittle heat in it i put my foot on the gas and revved it up and the oil gauge came back and light went off take my foot of the gas and it comes back on and gauge goes all the way down. SO my question is what do you think weak oil pump? or sending unit? Then my second guess was maybe since it does have a bad injector if it just has to much fuel in the oil and thinned it out so its under so many psi and won't read on gauge? How hard is it to change injectors? and the Oil pump? and while i am here i wanted to know can i make a 2wd a 4wd or are the frames different on the 2wd chassis? I got this truck for 5g's and its very very nice you would never guess it has those miles on it. It was a transport hauler. Thanks for any help.. And if need be i will just put a new motor in it but since this 1 runs good other than these problems figured i would just try to fix it first. Thanks again..


Sorry think i put this in another section too..

If you lost your engine oil pump the truck wouldn't run as it feeds the high pressure oil pump to fire the injectors. Probobly would be worth hooking a scanner up and run some diagnosics on the truck before you tear it down.

Did you check the oil level? In the pan and the Hpop? Sounds like it could be low.

Welcome to the org. You have a bountiful amount of info to be tapped on here. There are plenty of guys to help with your problems. I would check the oil level like Ditty said. And there is a plug on the HPOP to check level in there. You remove the plug and make sure oil is to the threads. Change the oil and see if that helps if its too thin. Use 15w40 Rotella or Motorcraft. 15 quarts. Some of the guages in the fords are crap. could be the guage. I would have a diag done on it to see what the oil pressure is. could just be the pump. Good luck

It'll cost you twice as much as you paid for the truck to convert to a 4x4. You'd need a Dana 70 or bigger, a transfer case, and a drive shaft just to get started.

I don't see why you would NEED a Dana 70 or bigger. The stock front axle is a Dana 60.

Thanks. I already have a SWB dana 60 front for it just need hubs for the DRW front. No i haven't checked the oil level yet. Is it possible with the bad injector that it would thin the oil out? Thats what i think it is but not sure yet gonna work on it today. Gonna change the oil in a bit working on my mustang right now so i can put it up for sale.. Anyone looing for drag car?
