Ok let me know when you are ready . Bleeding injectors on a larger diesel like that is easier with 2 people and I can then show you how to do by yourself in case you run her out of fuel one day .Eugen wrote: ↑Wed Feb 16, 2022 12:00 pmI don't about running fine though. Listen to the same model tractor that I found on youtube, sounds to me more smooth:DavidBarkey wrote: ↑Wed Feb 16, 2022 7:51 am If it was leaking past anyone of the plungers it would not build pressure and that cylinder would not fire and since you said it ran fine I would eliminate that .

Whereas mine sounds like tar-tar-tar-tar
Maybe that's a sign that fuel delivery or pressure wasn't right anyway.
( the other tractor is at a higher RPM and that will change the sound a lot , Now not perfect , yours definitely on all cylinders . )

I don't have experience with diesel engines so I'm not sure if it sounds like it's got a problem or not.
I can try to re-torque them, yes.What just accrued to me is if one of the injector pumps had backed out a little when someone in the past doing a repair that required removing the lines and did not properly re-torque them . Fuel would be able to leak from from the fuel passage to the shaft area . From what I can see each pump is seal at the bottom by clamping force. This type of leak could still alow the injector to function .
If there was water or coolant in the oil, shouldn't the oil have been bubbly/cloudy after it ran? A buddy of mine had a boat whose engine wasn't properly winterized so the manifold cracked and there was water in the oil. We didn't know right away, so we tried to run it, started for a few seconds and then died. But the oil was cloudy/gray.Other possibility is that at some point the was water in the system that froze and there is a crack internal , but i would expect that if that was the case there would have been other damage .
I think before going any further , A- drain some oil off and see if it has water in it or is just thin and smells of diesel , B- If it is water go down that path , if it is thinned out by diesel go to step C.
Not allways , if it has not been emulsified with the oil (milky) , it can sit at the bottom of the pan . and not be picked up by the oil pump
depending on how far the sump is off the bottom of the pan ( all engines a little different ).
DaveWill try the re-torque. But can't run it at all, as i'm missing those parts for the fuel return line and waiting for them, plus the feed pump. I'm going to take the injectors to a shop in Toronto to have them looked at and if needed fix/clean them.C- remove the lines from injector pump and make sure all nuts are free . release the clamps and crack loose each injector slightly to make sure move freely enough and re-torque down to spec. re-assemble, chain oil again ( don't worry about the filter just drain it and put back on ) and call me to come over and give you a hand bleeding the injectors .
Maybe mark the pumps before so you know if any tighten down more than they were .
