location?

Reno Nevada

I 'm sorry I need to revise my post. I just looked over his receipts. Parts replaced @ 90k, 10k miles ago. ( my cousin partied too much over the years)
Garrett turbo (blown)
Air Cooler Tube (torn)
Bosch fuel Ing. 4ea
Tranny Flex plate adapter, hub bolt & accs. (broken)Maybe the monkeys left one\more of the TC\flexplate bolts loose: loss = vibration, losing power when in\out speed sensors don't match cam\crank speed sensors - not even to mention: how did they know it was broke in the first place? Shoulda got new TCC and front pump..........
Battery
Fuel filter
EGR valve,gaskets & filter head kit (leaking)
Approx $4800

Glow Plugs replaced @85kmiles , his wife put unleaded in it, $2400 at stealership! Auto insurance paid for it ???

Thx for the help guys

I will, please elaborate on what you mean by scope testing.

As to what has been done to the vehicle in the past it was only listed to provide info as to what has been done previously, the money is gone the parts are new, he may or may not have been ripped off. I know for a fact that his wife toasted the turbo, if I remember correctly it was oil starvation.

P'raps nobody but you and I has a scope - unless your meaning is to 'scope' it out with a scantool?

I am pointing fingers, here, but specifically to a problem at which you should take a look: e pluribus unum

Huh?..no..I mean labscope. Do you think anyone is really interested in proper diagnostic with advanced techniques?

Yes - but how many here have that capability? Most have only an inexpensive (comparatively) scantool that misrepresents any DTC's that it does read

A scan of the MAF readings would help, but I don't see where his KJ is even running, at this juncture

Hell, I dont see where anybody has attempted to re start it after it died.

It could be a real simple problem. What exactly is happening when you try to re start the engine?

Seriously, this CRD sounds like a train wreck.

So try and fire it up and see what happens?

Unfortunately, when you are wading into a collection of repairs like this, it could be anything. If the turbo was actually bad and it was definitely oil starvation... Where'd the oil go? If the turbo oil line plugged somehow, that is one thing. If, however, the oil went into the exhaust like it does on many (most?) turbo failures...

Then the cause of the engine running badly right now could have a much darker reason than a broken timing belt. It could be catastrophic bottom end damage from the oil starvation of the main crankshaft bearings to the rods. This happened to me twice, and took out the engine both times.

It blew a shitload of oil through the exhaust

geordi · **Posted:** Wed Jan 07, 2015 11:51 pm

Oog, that isn't good news at all.

The reality is that the bottom end was probably VERY damaged by the loss of oil pressure, and if you attempt to run the engine any further, you risk ejecting one of the rods through the side of the block. It may have already torn apart one of the pistons, b/c that is what happened to my first engine after a turbo failure - the #1 piston was pounded to shrapnel by the broken rod under it, and the rod then punched out the oil pan while on the test drive after replacing the turbo and refilling the oil.

You will need to pull the entire motor from the engine bay, and once you have it on a stand, you can flip it over and pull apart the bottom end to have a look at how bad the damage is. Right now, this is salvageable... but it will require a lot of work. Unfortunately, you are in the worst possible situation for trying to sell it. There is a member here, Sir Sam, that might be interested as he lives in Colorado and buys and restores these things.

Unfortunately, there isn't much I will be able to do to help this CRD.

geordi, thank you so much for all the info, I'll pass it on. This may be a stupid question but my cousin asked if you can drop a regular gas crate motor in the CRD ?( I would think you would need to change fuel tank, lines etc)

geordi · **Posted:** Thu Jan 08, 2015 12:08 am

You don't need to change the lines or the tank, those are just carriers for the fuel.

There isn't an in-tank high pressure pump however, that a gas motor would require. The computer and the wiring would also need to be completely pulled and swapped with a set from a gas KJ... That starts to become more expensive and WAY more complex than just pulling the block and tearing it down. This is a VERY computer-controlled setup, and it won't be happy unless it remains as it was built from the factory or you have a truckload of cash and time to throw at it.

OK that makes sense! Last question. The Jeep ran for a 3/4 mile with the engine idling down hill, no rattling or major sounds aside from the vibration, wouldn't a crank or main bearing issue be making any kind of ungodly sounds?

Not necessarily. The vibration could be because the engine is now unbalanced from a connecting rod and piston no longer being attached to the crankshaft. Both of my engines failed with minimal loud calamitous noises, the second engine put the #4 rod end through the side of the block with nothing more than a tapping sound that could have been an injector or a broken rocker.

LOL, OK what a bummer, oh well, I sent a PM to Sir Sam along with the thread. I appreciate all the help!

Good luck, sorry I couldn't be more help or have happier news. If it's any consolation, you aren't alone with this failure mode, and you probably won't be the last. There is a good chance that there are more than a few CRDs that died in this way that never had the benefits from this forum, and are now razor blades or Kia Sephias or something.

Haha well said! Again, I thank you sir as does my cousin the once proud owner of a running CRD. We'll see of Sir Sam is interested, would you like to hazard a guess as to value assuming the worst case senario?

geordi · **Posted:** Thu Jan 08, 2015 1:19 am

It isn't going to be much... Depending on the condition for the rest of the truck and driveline, you could be in the 2k-3k range, but I doubt any higher than that. It could also be as low as 500-1k, just because you are looking almost certainly at 2k in parts and a full teardown to even see what has happened and attempt a fix. The only bright spot (such as it is) is that the block hopefully is still in one piece.

I wouldn't let it go that low. There's about $300 in scrap metal there and there's a ton of stuff you should be able to easily part out e.g. the control modules.

...but, if it were me I'd have the timing cover off and take a quick peek in the cylinders with a borescope. Giving up on it with unknown issues is a sure fire way to attract bottom dollar for it.
