What is it? The diesel suddenly knocks!

I dont know. I'll think about it. Broke off a small piece. It does not to interfere for the work of the piston. What do you think?

In Russia is not parts for 6,5 diesel. Shipping from USA will be 1-4 weeks. Now my truck stands in the street on the outskirts of Moscow. And now I do not have a free garage for repair. So I pull the engine out only when all will be ready for repair.

Pull engine, drag vehicle out of garage and put it out of the way. Drag next project into garage. When parts arrive drag or push vehicle back into garage to finish repair.
 
Buying a block (possibly), rods, pistons, rings, etc.- Forget that noise- you will still be dealing with a questionable block and crankshaft. IMO-2 words: BOAT ANCHOR.

Start with a different engine. What would be your budget for new engine or rebuilding one would be my first question. I played the "replace the parts game enough. Best move I made was buying an optimizer long block. Now that the p400 is available that is by far the best option if you can afford it.
 
Will, you forgot I live in Russia. Shipping the engine from US is 1500-2000$ and 2-3 months. You are rite the best way is new engine. May be I'll do it to next summer.
 
AM General HMMWV uses the 6.2 / 6.5 platform. That is what the optimizer and p400 were actually built for. I would like to see you get one from Leroy, but if not I was thinking some should be available in Europe. Germany maybe? Then patch it together, run it on 7 cylinders if you have to, order one from Leroy and do it when it gets to you. A p400 would outlast the rest of the truck no problem.

The pistons will not work from the 6.2, but rods should.
 
I think about this block:
Option 1: I leave everything as is. The piston should work. From the broken edge to the area of ​​the rings is the long distance. Crankshaft will bee different.
Option 2: I'll install the cylinder repair sleeve. Crankshaft will bee different.

The P400 is the king of the 6.5 world. The up armoured hmmwvs were having problems with the 6.5 once it weighed over 12,000 lbs. AM General basically built it stronger in every way they could, and still have the same platform.

I don't know if Leroy can ship to you, you need to contact him about it. More info out there, but here is a start.

I remembed you talk me about p400. Great diesel but very expensive for me. I think when I got it in Russia, it will cost $ 10,000. May be next time. Next life.
 
Ok, got it.
If the rings don't get to that area, try running it with the sleeve.
Use the crank and rods from the 6.2.
Reuse the pistons in it if they are ok.
The head bolts are designed to be used once then replaced, are you reusing them? Some people get lucky reusing them, others don't.
If you replace them with new, using ARP studs/nuts instead of bolts costs a little more the first time, then can be reused forever.
 
I forgot about the difference I the seal for the cranckshaft, keep the 6.5. The only reason I suggested the 6.2 crankshaft is possible damage when the rod bent.
The rods in 6.2 and 6.5 are interchangeable afaik. Since your 6.5 is bent, and you have the 6.2. If your putting an engine together that is already troubled with the crack, I would spend as little $ on it as possible unless you would for sure use them in a replacement engine down the road, like head studs.
 
You are sure there is only 1 crack? Main webs in the block ok? Head bolt holes crack free? These engines fail and are not able to be rebuilt cheaply due to cracking. As the cost for parts there appears to be higher you can do expensive crack repair.
 
are you sure that's a crack and not a score from a previous engine problem? A crack like that should have pushed antifreeze out the radiator
