Cracked 2000 7.3 block

[Derek525]

This is my first post, unfortunately while driving home on the freeway the other day I heard a kind of a pop. When I looked in the rear view there was a huge cloud of smoke. I immediately pulled over and shut the truck down. After I got out I noticed oil dripping everywhere. I thought it might have been the High pressure oil pump or line. To make a long story short, I found a 6" crack on the driver side of my block near the front of the motor. The motor turns over fine, there was no missing or knocking before or after this incident. the motor will not start because there is no oil pressure and oil and antifreeze have co-mingled. Does anyone have any knowledge as to why this would happen? I am looking for a new block now.

Thanks

hmm. well it's right near the engine mount. may have something to do with the location of the fracture

Holy Smokes That sux man. How many miles were on it? And what is it in? Might be better off looking for a new truck. And scrapping that one. I think you can get a short block for about $4k. But you gotta pull the cab off to do any work on these.

You don't need to pull the cab on a 7.3 truck. You can pull the engine cab on.

Id just go get a engine from a salvage yard or Craigslist. Rebuild and drive her some more

Any mods done to the truck?

Wow! They just don't make metal like they used to, with recycling & all.

Plenty of mods: 4" Exhaust, WW, Full ATS Trans, Boost Relief, CAI, DIY STGIII Hybrids, Regulated Return, GTP38R. Was not abused, about 200k. Ran great.

Looks like a rod let go to me , just didn't make it through the block. Here's an option but it's his first post

Mine made a pop too at 111k but looked more like.....



Someone else had a black mamba motor for sale , cant find the page though

Just picked up a rolled 01 with 140k w/gtp 38 turbo, rebuilt trans and rear end. figure I will throw in bearings and head studs and gaskets and put my aftermarket goodies on it and sell the rest of the running gear. Maybe find a block and make another engine with the other parts for a spare. Oh I thought about a broken rod too, nope everything rotates fine. will dig into it more later.
