So you think it is safe to turn the engine over and start it ? AE doesn't do the relative compression test. But it will do power balance and you can shut off injectors. Any chance a glow plug broke off and is hammering on a piston ?

Got Auto Enginuity connected. This truck has sat for the last 5 months. Battery voltage was low. I have the charger on it now. Pulled DTCs. Nothing significant. The alternator went out on this truck a while ago, so there were several CAN bus non communication errors and low battery...

How do I diagnose a bad injector ?

Thanks for the advice, guys. I'm worried about further damaging the engine by turning it over/ running it. What is the relative compression test going to tell me other than a cylinder is bad. The next step will be to pull the heads, right ? Why not just go straight to that ? Am I wrong to...

How do you suggest I proceed with diagnosing it ? I have Auto enginuity. It sucks in during the intake stroke. Oil makes its way by the rings if the bore is messed up. I was going to pull the heads with the cab on. Is that the next step ? I'm garage less for the summer. I have to...

Probably a cracked piston. The regens were probably caused by oil blow by when the crack was small. Now the crack is big. A spun rod bearing probably wouldn't just happen at idle and it doesn't explain the the regens before it happened. Will the bore be ruined if the piston is cracked ? Can...

Then it has to be a cracked piston or a spun rod bearing. If it is these, can the engine be salvaged ?

It has 200K miles on it. It is completely stock. It was regenning quite a bit before it happened. Fluid levels appear normal. Broken crankshaft ? Spun rod bearing ? Dropped valve ? Cracked piston ? Head gasket ?

Is it safe to run ? It knocks pretty hard in real life. I'd say there is no significant miss fire. This happened at idle. I never revved it up. Any chance it is a sticking valve and I could just replace the head(s) and have a running engine ? It was down on power a bit before it did this...

Was running errands. Started it after it sat for a bit and it made this sound. Towed it home. What is wrong with my engine ? https://www.dropbox.com/s/dvn31mjk4xrb1sv/20171017_184126.mp4?dl=0

Will this engine run with the stock ECM ?

It turns out it was the charging circuit. A few weeks ago my alternator light came on. Long story short, I replaced the alternator and the truck no longer high idles. It starts way better too. It is quite a job to replace the alternator. Don't do it from the top. Pull the passenger...

You are correct, it was the upper hose, not the lower hose. I replaced it and the leak stopped. No more coolant loss.

I replaced the alternator in my truck a couple weeks ago. Had to obviously loosen the belt to do this. WTF were they thinking putting the tightener where they did ? It was easy to get to on the 7.3s ! Everything was easier to get to on the 7.3s. If you get stuck doing this job, pull the...

It started doing it this summer in June. The truck is stock. I changed the diesel particulate filter because it was plugged about 2 years ago. It worked fine until this summer. It is not doing the warm up high idle. It does that fine when it is cold out. This is a constant high idle at...
