Default swap

I was thinking out loud and figured I would ask if anyone had tried this If I had time I would give it a go just because I like challenges however the engine will be out int he morning and apart and coming and off to the machine shop sometime Tuesday or Wednesday am. I have came across a full rebuild kit with all name brand parts so I'm going that route.

thanks for being a sounding board

I think you are on the right path with the rebuild.

Get some digital pictures of the bad hole/piston crown and post them, please! We all love to see (other peoples) carnage!!!

Cool photos of damage

check out the photo album posted photos of damage along with the surprise I found a bent rod the red you see in the picture is a glare off the inside of the truck bed it was laying in

its off to the machine shop will know how I'm fixing it Friday

I will say one thing about this engine it doesn't lack iron i think the block weight as much as a 6.5 short block put together crank is heavy duty was a little surprised that the main bearings are only 13/16" wide and the main caps are almost 1 1/16" wide
everything else in the engine show no sign of wear at all.

We just replaced a 2005 LLY in a C-4500 the other day. The posted shipping weight on the crate was 705 Lbs. The engine comes in a big enclosed plastic crate. The weight does not include exhaust manifolds, injection pump, turbocharger, EGR cooler and valve, flywheel. Those are the major parts anyway. So Iguess the engine fully dressed weighs between 800 - 850 Lbs?

Thanks for posting this - I feel very very fortunate that these are not pictures of my engine, near Spokane two summers ago.

Everyone driving an DMax that is 'smoking a little', but still being driven should take notice! I have been very guilty but have been lucky not to have one open up like yours did.

Unhappy Update Not Good

someone asked the head is fine however the block is not good anyone happen to know where I can pick up a good LB7 Block or tell me a machine shop that can bore this block,

I received a call from my machine shop (being using same guy 20 plus years) the block is what they referred to as leopard block around the top of the cylinders thye have induction hardened the place if you look at it they look like leopard spots. they called there machine shop resource asking about a bulletin that they have that shows you can not cut this with a boring bar. He asked how they are over sizing this engine he was told they are honing to the all the way to the over size how ever to install a sleeve they would have to take .125" all the way around to make a sleeve fit that is if they can find a sleeve for this engine no one list a sleeve for it e told me the names of the sleeve companies one i think was LA sleeve not sure about the other was in to much shock to find out I can not fix this engine. the industry resource told him he did not know of anyone sleeveing a Duramax block he figures its being done just not sure where.

so anyone has a good LB7 email me or if you know some one that has sleeved one of these blocks point me in there direction please everyday the truck set I lose money guess I guess night have to bit the bullet and by a used engine I found $4000 with 112K on it with a warranty.

Well the engine had to come out, anyway.

My advice would be to spend the time looking for that low mile 2003 early 2004. Don't get in a hurry, and buy a high mile LB7 engine from the lowest cost supplier, only to find out later it was a 2001 with a smokey set of injectors.
  • Know the year and VIN of the engine;
  • Know the miles and circumstances on the donor truck (no rollovers - they might have run/sat upside down and hydrolocked);
  • Know the injector history by running the VIN with GM.
4K for 112K mile engine is no bargain, if you ask me, especially if you are doing headgaskets and/or injectors this time, next year!

Be patient get on the internet and phone - call Kennedy Diesel, call the Performance engine builders nationwide someone has what you need for the right money, in this TIGHT economy!!!

I got lucky a few years back and found a new LB7 that came out of a 15 mile truck. Thats right...fifteen miles... Paid $5K for it, complete, was going to swap it into my high mile 2001 with head gasket issues, but decidede to sell the truck, as-is. Later sold that engine to another DP member for $5500 IIRC...I knew it would only be worth more and more - but the cash money was nice, too. Here is the guy I bought that engine from... http://marineduramax.com/6.6-liter-turbo-duramax-diesel

Good luck!
