7.3 IDI Turbo - Knocking - Rough Idle
Mine sounded worse than that a few days ago and I was certain I messed up the engine..I started it today and it almost sounded normal again. So I’m guessing I might just need injectors and the tune up..could it be that simple? I realized I thought it was sucking down coolant but I did drain off...- 94turbocrewcab-lb

7.3 IDI Turbo - Knocking - Rough Idle
So I’m going to pick up my buddy’s test kit, but I figured I’d update. I dumped a gallon or so of atf in the tank the other day when I changed the fuel filter. I also filled the filter with atf...ran it a bit and let it sit..ran it..let it sit..and it sounds pretty good now. But I found a video...- 94turbocrewcab-lb

7.3 IDI Turbo - Knocking - Rough Idle
I’m waiting to find a quality compression kit to borrow. My mechanic seems to think the steam I’m seeing is oil vapor/smoke and not steam. When I crack number 5 injector the knocking does go away to a certain point.. When this all went down my turbo was squealing as well. And I used maybe 1/2...- 94turbocrewcab-lb

7.3 IDI Turbo - Knocking - Rough Idle
I’d just think I’d spend the extra money on rebuilding my turbo motor. I also found another 7.3 idi 1990 dump truck really clean down south. Might buy that and rebuild my turbo motor.- 94turbocrewcab-lb

7.3 IDI Turbo - Knocking - Rough Idle
I’ve never gotten this far into a truck before. Any rough estimates on time to swap motors? I’m thinking I will just get the stock idi motor and my son and I will rebuild out stock turbo. I have the c6 auto. Wanting to swap for a 5 speed. But that can come later when it’s running again...- 94turbocrewcab-lb

So the only ways to have steam and water drips out of the ccv tube is either HGs or cavitation?- 94turbocrewcab-lb

7.3 IDI Turbo - Knocking - Rough Idle
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...- 94turbocrewcab-lb
