    Fuel tick/knock

    So I’ve had this annoying ticking/tapping that happens between 1300-1700 rpm when I’m hitting the throttle pedal. It’s kind of hard to diagnose though since it really only happens when I’m driving. But I’m pretty sure it’s injector or pump related since if I take my foot off the pedal it goes...

    High Idle/Cold Advance Question

    Does anyone know at what water temp the high idle and cold advance are supposed to kick off? Currently mine shuts off at about 130F. As the truck gets closer to temp it’s starts to sound likes it’s gonna run away LOL. It a slow crescendo where it gets really loud and fast and when it shuts off...

    Doomsday Dually Project

    What’s up Oil Burners? So a little background on my truck and this project… I bought this truck off a co-worker in Jan ‘23. It’s a ‘93 F350 7.3 IDIT, 4x2 manual trans. Body was super clean and so was the frame… but the rest of it was in a bad shape. The truck wouldn’t start when I bought it...

    Piston Damage

    So my IDIT motor has been at the Machine shop for about 6 months. Now the guy has finally gotten around to putting the bottom end together after sleeving all 8 cylinders. He let me know that the new Mahle Pistons I gave him to use all have damage in the same area around the oil ring and that he...

    Turbo Elbow Gasket?

    So I got a stage 1 drop in turbo from R&D, and I got the install kit from Russ. I didn’t see a gasket for the turbo elbow though. I sent my factory turbo to Justin with the elbow on it, so I didn’t take it apart to see if there was a gasket there. Do you have to seal these two surfaces with any...

    Performance Clutch kit that will work with OE Flywheel?

    Anyone know of a clutch kit that will be okay for 300hp and will work with the OE flywheel on my 93 IDIT? I had the flywheel resurfaced but after checking with Southbend they say there clutch won't work on the OE flywheel.

    Cheap way to Intercool?

    So I’m working on a build right now, and originally I was going to put off inter cooling since the cost seemed pretty high. I saw CDD has a kit for like $1500. But I think I’ll have better peace of mind if I just do it. I’m going to be head studding, upgrading turbo, and upgrading IP to 90 or...

    Cavitation?

    Pulled motor to reseal everything since it’s leaking from everywhere. After I took the heads off I noticed when I turn the engine over manually, cylinder #8 would leave moisture on the cylinder walls. I’d wipe it, cycle again and same thing. Motor is at 250k mi I’m hoping that it’s just some...

    Diesel Rx Glow plugs

    So I ordered glow plugs from accuratediesel. Stupid of me. They sent DieselRx plugs. I installed them and they worked for half a day before they all burnt out. Bought some motor craft plugs to replace them with but none of them will come out. They are all ballooned at the end. Also, I’m...

    Fuel line help

    so my fuel lines are rusted out and leaking. The fuel tanks were too and I already got the replacement polyethylene ones with new pickup tubes and shower heads etc. Anyway I’d like to replace all the fuel lines. I think I’d get a flexible nylon, but my question is how are you supposed to join...

    Oil leak source?

    So I just picked up a 1993 7.3 IDI factory turbo, and there appears to be a huge oil leak in the engine valley/back of the engine. The valve covers are 100% leaking but I’d be surprised if they are responsible for this mess. It looks like oil sprayed all over the firewall. there was also some...
