Hello, I've had many diesel trucks but this is my first IDI truck. I've owned it for 2.5 years. It's been extremely reliable. But lately I've neglected it just a bit. I know it needs the front axle overhauled. Planning on doing that after my spare truck is up and going. It is getting oil changes and fuel filters though. My son and I had a break down in it the other morning but made it close enough to home to get towed back by my wife! 7:15am
The truck was making a slightly off noise sort of like a loud knock coming from the intake. I didn't think anything of it and left for a meeting. Shortly after getting down the .5 mile drive way it really started sounding odd. Turbo Squealing when you give it 1/2 throttle and the injection sounded awful. So we turned around after a mile. Raced home..after about a mile I was giving half throttle to get down the road at 25mpg. Then it just gave up...I coasted over to the side and ran home to get the family. I tried turning it over when I got back ( about 10 minutes) and it was slow turning over and batteries seemed dead like they were dead. We towed it home and left it there on the battery charger.
Next morning I added some oil to the engine it was lower than the night before. It cranked over fast with the freshly charged batteries and it fired up. Sounded horrible and knocked and shook. I turned it off and changed the fuel filter. It was 9k miles old and had very little water in the bottom. I topped the radiator off with water. It took about a gallon?! I was planning on a coolant flush but it's been low on the list unfortunately. Im thinking a need a thermostat but I only drive 20 miles at a time and it never gets that hot. It's about 30 degrees here. So anyways. I filled the filter with straight atf. Put about half a gallon in the tank and fired it up. It ran a bit better and stable.
So currently the truck has the turbo inlet exposed. no air intake or intake box. Ive removed the belt so I can hear just the motor. My power steering pump makes a gear grinding noise when spun by hand. There is one injector that does account for most of the noise. But I still hear a loud knocking noise. It will run but knocks and sounds like a gas job with cracked exhaust manifolds when you give it throttle. And oddly enough steam and WATER drip from the CCV tube. Lots of steam from the oil fill.
So...do I have cavitation or maybe blown head gaskets?
I can only find normal non turbo 7.3 IDI engines.
Thanks! I need to get this figured out. I tow my tool trailer to job sites with this truck. It might be easier to park this one and get floor pans in my dodge and use that for a while.
This truck is a 1994.5 7.3 factor Turbo IDI. Front axle from a 97. Minimal rust and 269K Miles. I'd like to keep this truck going but don't need to daily drive it.
