Agree with foton, something's wrong with your compression test. Not sure what you mean by "injector probably has a check or something". You have to remove the injector. The compression test kit should have an adapter to fit in its place.

if the injectors do not come out easily there might be carbon build up on the heating element of the glow plug. use a penatrating oil to soak around each one and let sit for a bit. when you get the threads out of the head pull easy and spin to remove and try not to knock off any carbon back in the cylinders, when you get them all out spin the engine over briefly to blow out cylinders just in case. upon reinstalling use some anti seize compound on glow plug threads.

The older Kubota used a indirect injection system and needed glow plugs year around when the engine was cool to cold, that was back in the 80ts up through the early 2004 if I remember, it also made the engine pretty sooty, and I have seen them on light towers with excess of 12,000 hours, with that said I don't know how many had run out of fuel over night and the ignition was left on, we always added an extended remote oil filter to them up until about the year 2000, I think by year 2001we started selling the units by about 5000 hrs.
No go
So now I definitely have to pull the head, the damn injector broke I was wiggling it and got it out . Thing is all rusted .
&*&^%^(^(^_(&*%^$&^$.....Darn. Sorry. Was just looking up some general how to do a compression test info to send you, but guess ya don't need that how. I'll send you some additional info on the engine tonight.
So now that I have the cylinder head off. Only took 3 hrs. Anyways, probably should magnaflux if for cracks . My bigger concern is the fact the injectors were rusted so badly. I'm hoping head gasket, or probably cracked head. Might have to check the cylinders for wear as well. Any input on what you'd do is welcomed. I do say it wasn't as bad as I thought it'd be. Plus my 11 yr old learned how to take apart an engine. Thanks in advance. Nik
on the bright side I do not see much ridge in the cylinder. run a good machinist straight edge on block deck look for flatness. I remember reading something about water collecting around injectors on machines that live outside and rusting up on some models and someone made a water baffle to route water off the engine. of course I do not know if this is your issue.
Yeah I think its previous life was outside. I think replacing injectors is a definite. Are they supposed to come apart? I know there's a few pieces to them. Not sure if they are salvageable.
a diesel shop that repairs injector pumps should be qualified to check spray pattern and repair if possible. I would have to go with their advise on the condition of those you have. but it might just be better off buying new set, or newly reconditioned set if yours are to far gone than go down a black hole of trying to repair those since you already know one is broken.
Trying to find new ones. Local shops can't find them. Also I took the head in, the owner showed me where it was leaking. He's resurfacing and a valve job. This thing will be as good as new ….
