    7.3 IDI Knock

    I thought that was just the firing order. And the exhaust temp did seem a bit higher than the others. And thank you :)

    1996 F-350 Powerstroke buying thoughts

    Can I have your guys' opinions on this? This guy has a 96 F-350 Powerstroke with a manual transmission and it is 2wd. It has 330k on it and he says there are no mechanical problems associated with it. It is listed as $3500 obo. Does this sound like a good deal to you? The front part of it is...

    7.3 IDI Knock

    I wonder if a compression test would tell me if anything is up with the #5 cylinder. I used my infrared thermometer to get the temps of the top of the injectors and they all seemed about the same +/- 5 degrees except #5. That injector was 10-20 degrees hotter. So could that possibly mean I have...

    7.3 IDI Knock

    A pov auto pool on base? Never heard of it lol. There are a few wrecking yards about an hour away from pendleton and also a few by 29 palms. I've only been to one near 29 palms since I'm here for a shop rotation. Saw a few IDI's but I didn't know the engine status and they looked like they had...

    7.3 IDI Knock

    I'm not sure if it's an exhaust leak. How would I check for those? Just look for cracks in the manifold? And the noise stays exactly the same, possibly even quieter on higher revs. It just goes faster. Also if I put the throttle on can hear the knock like in the video. If I'm going and then all...

    7.3 IDI Knock

    I've been starting to wonder if it's a cracked piston. Maybe even a slapping piston but it sounds like it's at half the speed the tach says. If this is the scenario, what should I do? Most new diesels are expensive and require smog. I've heard really good things about the 7.3 IDI but it would...

    7.3 IDI Knock

    I've ran a bunch of lucas through it and a bottle of diesel klean before. Both at different times lol. They seem to make no difference :( I will take a look at the springs again. They seemed to be fine last time I looked at them though. I'm pretty sure the sound is coming either from or very...

    7.3 IDI Knock

    There's no way it can be a lifter. I just replaced those and the pushrods. It has the same exact knock to it that the old ones had. I have looked around the exhaust manifolds and have only seen a little bit of caked oil from when the valve cover seals were leaking. But I replaced those since...

    7.3 IDI Knock

    I really don't think it's an injector. Like I said, I swapped the #5 injector with #6 and it was the same thing. If I crack the injector all the way, the sound gets a lot quieter but you can faintly hear it still. And there is no smoke either. Just a small puff of white smoke on a cold start but...

    7.3 IDI Knock

    I have had to add a few quarts of oil over the 5 thousand mile period since I've changed it. I added delo and it seems to have not been consuming it that much so I'll probably use delo next oil change.

    7.3 IDI Knock

    Haha I've heard that phrase so many times lol. Rotella has seemed to work alright. A little bit of oil consumption but not too bad. I took a video of the knocking sound and I will upload it a little later. I actually used a pool vacuum hose to listen to the sounds. It didn't sound like it was...

    7.3 IDI Knock

    Yea it's a 93 factory turbo engine. Funny thing is, is that the truck is a 92.5 and the engine is a 93. probably their first turbo'd model for the IDI. Last oil change was when I first got it around 343xxx miles. I did the oil and filter change. Used a motorcraft filter and rotella 15w-40 oil...

    7.3 IDI Knock

    Hey guys. I'm new to this forum and thought I'd post this here. I have a knock on my turbo'd 7.3 IDI. I've checked the injectors, replaced the lifters and pushrods, and set the injection pump to stock timing (lined the marks up). Now here's the thing, when I crack the injectors the knock is...
