#4 glow plug, looks like new. Here's my theory, I've examined this nozzle under a magnifying glass, it looks just like the tip blew off, it is split perfectly flat across, so perfect you would have had to cut it with a saw to make it look like that. I think the tip blew off, looks like when metal or aluminum is spun and it splits open, and a tiny piece of the tip held it, but when the tip blew it went straight down and dome of piston barely tapped it pushing it back in place but just off center. The noise I was hearing was the cylinder being full of diesel causing terrible labor knock. Also when the end came off that nozzle rail pressure would have drastically dropped.

I'm really seriously considering dropping another injector in that hole and driving on. If there's anything in the cylinder I should know right away. I've got another entire engine setting on an engine stand, head off injectors out, so all I gotta do is drop injectors back in it and crank it.

Congrats! I read about them blowing the tips off from water (or maybe it was the other tiny particles) in the fuel. Wwdiesel linked the article I think. Maybe you want to add some water dispersing additive for a tank or two?

I would crank it over without letting it start and run it if it sounds ok, but that's just me.

Oh, btw, I haven't updated my profile, I now have 220,000 miles on it, and to bring u up to speed, I bought this jeep with 200,000 on it and the owner had never touched it. It had factory everything, and to make things worse the guy had run conventional 15-40 shell Rotella in it all the time he owned it. He said it was running rough so he took it apart but couldn't figure out anything. First thing I found was the intake ports were so clogged you couldn't even stick a pencil in the silver dollar sized ports. Also about half the rockers were wore slap out, they wouldn't even touch the valve stem. About half the valves I had to drive open with a shop hammer because they had so much gunk and tar junk, but when I drove them open they stayed open. I got a spray bottle and sprayed kerosene around each valve stem every day. Btw, I did not pull head, just intake with cam assembly had been removed when I bought it. After a cpl weeks I walked in my shop and the valves stuck open had closed, but when I hit them with a hammer they stayed.so every day I walked through my shop I sprayed valves with kerosene. I never heard it run, had no idea what it was gonna do. So to keep from sinking a bunch of money in a dead engine, I had already bought a low mileage engine cheap, just in case. I put a new timing belt on, cleaned all ports, and used a small propane torch and burned the gunk out of all ports.i pulled the used rockers from the second engine, and I take assembly with cams, cause my old cams were shot running on worn out rockers. I zero'd everything in set my cams, marked them, and installed cam pulleys, which everyone said I couldn't do, but those cam shafts are tapered and the pulley will not move, but even if it did I had each marked so I could tell if it moved. Stuck it all together and it purred like a kitten for the last 2 years until yesterday. But this engine still has lots of life in it, I know some disagree, but besides the insufficient top end, these little engines are tough as a rock, I have a programmer on mine, and drive the dog out of it. It is the only automobile I know of on the highway with a wet sleeve in it. I have a perfect low mileage engine setting in my shop, if I ever need it, I will stick a new head gasket on, put the factory head bolts, and torque them to the torque specs of a stud and drive on. I think back a cpl years ago when I was on here several guys did test and discovered the factory bolts did not stretch as we were told from the professionals. I know what has held up for me, and I promise nobody could drive harder than me. I DO use the best full synthetic oil, with a quart of full synthetic Lucas Oil treatment. I change oil around 10-12,000 miles.

It is possible that water hit it, but I run a real good water additive plus I run the Grey jug diesel kleen every time I fuel up. It doesn't make any sense, and I was jus creeping along when it happened, normally I'd have had my foot on the floor, but it was cold yesterday and I try to stay out of a diesel engine when it's cold until the engine has came fully to operating temp.

at the end if it is only injector tip problem then it does make sense , because too much fuel conditioner can force water out of fuel system , so water has lots of surface pressure and can easily blow out injectors tips and i did see this problem on cat unit injectors , so i think overdose with fuel condition can be harmful to

Ok guy's, I'm man enough to come back on here and update this, so do give me a hard time,, but I went to shop tonight to stick injectors in, but I wanted to spin her over one more time. I guess setting for a cpl days has let antifreeze seep into the cylinder because as I spun it over I was getting drops of antifreeze blowing out the injector hole and I stuck my thumb in and no compression. Soooo, I'm guessing it dropped a valve, I just don't understand how it's not making any noise as it spins. At this point, I'm not sure what direction I'm headed. I have a spare engine that had around 98,000 on it. It had been in a wreck and broke the timing cover and cam sprocket. I took it apart to see if it had internal damage which it didnt. It had 2 broke rockers which saved it. But I took the head off and inspected it while it was on my engine stand. I just put over $500 in new snow tires on her. The man I bought it from had just put a new turbo and alternator on it. I'm seriously thinking about selling the whole package deal to someone younger than myself. I have a bad back and just don't know if I can hold out to take on a job of this size anymore. Throw me some offers on the table guys. I'll post some pics of jeep, but please don't low ball me, I've priced these engines and the average price for a used engine is 4k and up. I will let mine go cheaper because it will need a head gasket and the head bolted back on, but I'm not giving it away. I can sell it for a core and get $1,600 out of it so please don't insult me.

And the lesson in all of this is to ALWAYS perform the basics. Compression, fuel delivery system, etc.

Thanks for posting your initial diag. If I lived closer I'd come tear it apart for you.

I bought a complete running engine for $3200, with a warranty too - so I don't know where you have been looking on engines. Sorry, I won't be offering anything either.

Josh, you DO need to admit your problem though. :goink: :jester:

Are you selling a whole liberty or just the engine?

Hey I'm currently down to only 2. That's like 7 less than others. Haha

I don't have time for a project at the moment

If I sell I'm selling it all, libby and the second engine. It wouldn't do me any good to part with either of them and be stuck with the other. The 2nd engine is on my engine stand with head off for you to check out. It does come with the common rail pump and exhaust manifold, flywheel, balancer etc. It doesn't have the timing cover which shouldn't be an issue if your replacing an existing engine. Throw me something on the table, if your interested, but my statement about not insulting me with offers, obviously I'm not gonna sell a good engine and the libby together for 2k when the engine alone will bring much more than that. I'm not pressed at all to sell it but I've already got so many projects and a bad case of arthritis that I just don't care to proceed. I'm thinking of selling everything and putting some with it and buying an older 4x4 cummins. This is the first time in 20 years I haven't had a cummins setting in my driveway and I miss it.

Ok, fair enough - I don't think most of us realized the size of package you were talking about.

One decent condition Jeep needing work and a spare engine needing work does add to more than either by themselves. It still a gamble and needs transpo figured out too, so not just a "come pick it up with a tow dolly and go" kind of deal.

Out of my budget and potential (no space) at the moment, so good luck to you and whoever buys it. I will be happy to offer labor assistance and my skills with these engines though.

Actually, it all could go on a tow dolly, the spare engine and all parts could sit in cargo area on some cardboard and it would tow with no problem. Actually I'm glad you said that because I forgot about using a tow dolly. And we have a u haul in corinth so if someone was driving some distance you could reserve a dolly in a neighboring town and pick up here instead of having to pull a dolly all way here and back home.

And one more thought guys, you could pull existing engine, replace with good engine, take the one you pulled and put a piston and liner in block, and pick up a used head and you've got a spare engine again. I've saw several pistons and liners on ebay for cheap, and this motor was perfect before this week, you want here one run any quite than it did.

If it wasn't a broken glow plug, then I don't see what else it could have been that impacted the injector.

I would think that a dropped valve would have done a lot more damage to the injector tip.
