Q
IDM questions / buzz test code
So, you don't like the Accurate Diesel valve cover gasket/harness? They made the wiring pass straight from the plug on the outside of the gasket to the glow plugs and injectors on the inside... So there's no plug on the I side to go bad or come loose. Seems good to me. Might turn my old VCG into...- QuercusRubra

Why would putting in a different IDM make my truck run badly? Sent from my Pixel using Tapatalk- QuercusRubra

Q
IDM questions / buzz test code
Not a Doorman VCG / UVCH. I used the kit from Accurate Diesel with the wiring direct out of the inside of the VCG. I jectors are correct stock code from Full Force. All the same, no LL. I swapped the injectors around to rule out a problem with them and the cct fail code stayed with te cylinder...- QuercusRubra

Q
IDM questions / buzz test code
Quick background, there's too much to say, but... I can tell by feel there's a slight miss, and cct fails on 4 and 8. I replaced LOTS of things so far for various reasons, incl. rebuilt inkectors. Just for kicks I tried putting in a spare supposedly good rebuilt IDM that a mechanic had left...- QuercusRubra

Q
Running compression test... How to
Starting a new thread because this isn't just about my problem... Question: after watching DieseltechRon's video, I want to do a running compression test, I just want to confirm the process before I blow something up. So I'd pull just the glowplug on the cylinder I'm testing and unplug the...- QuercusRubra

Q
7.3 slight miss, knock, but compression and injectors seem OK... What could it be?
Mmmm. That's a good thought. I should go around checking for loose bolts and such. I wouldn't say I'm sureits under the valve cover, it's just what I've come up with, especially with the cct failure. At the moment I'm leaning towards a weak cylinder 4 and idiopathic cylinder 8 cct failure that's...- QuercusRubra

Not suckling air, I'm pretty confident. I resealed and fixed all that stuff, and I have a fuel pressure gauge, so I think I'd notice fluctuations if it was suckling air. That was the problem in the first place, though, I bet. Whick brings me to a question: what internal damage would be caused...- QuercusRubra

The heater works, but I haven't tried it in this case. I can say that in the summer when it was hot it smoked just a little, I'd say not much. I'll try the heater now, for comparison. So what would this tell you? Sent from my Pixel using Tapatalk- QuercusRubra

Yes, when warmed up, I don't see smoke. Also, it runs much smoother. I did unplug injectors, one at a time too, and they all made a big difference in idle, all about the same to my ear. Maybe I'll leave the valve cover off with the truck outside overnight and see if unplugging an injector...- QuercusRubra

It's a new IPR valve, so I doubt that's it. But how did you clean yours? There's always a possibility of some bit of dirt getting in somewhere when I had everything all apart. My impression is that if dirt did get in somewhere, it would probably make it all the way to the fuel injectors, are...- QuercusRubra

Thanks for your response. The truck does run better now than when I got it. These are new rebuilt I jectors, not my originals rebuilt. I removed the tank, scrubbed inside and rinsed it well. Replaced the pickup with the Dieselsite hutch mod kit and the inline spinon filter. I have changed...- QuercusRubra

I bought it with reportedly bad injectors. Stomp on the throttle, it would sputter or hesitate, make a bunch of smoke and make a scary loud kackl like grinding up walnut shells. Even when sitting if reved to a certain point, maybe 1500 it would start to billow a cloud of smoke and kackle or...- QuercusRubra

I have the Dieselsite regulated return kit along with the hutch mod (in tank pickup) and hp oil xover. Fuel pressure on the regular output is always a solid 62 to 64. I wonder if I should try turning it up a little, tho 60 should be plenty, right? Sent from my Pixel using Tapatalk- QuercusRubra

99.5 F550 7.3 Powerstroke 4x4 ZF6 Makes a knock when driving that has a metallic ring to it. Sometimes it's barely there in the diesel noise, occasionally it's so loud that nobody can miss it. Computer is reporting cylinder contribution failure on #4 and #8. However, I swapped them with #2 and...- QuercusRubra
