lets hear some opinions on what broke, my guess is crank.

Were tearing into it monday to find out what exactly happened, but we think crank broke.. we haven't had many problems out of our 6.7's so far. This will be our shops first motor. We have already had a few lose glow plug tips, but they were warrantied.

What would break on the crank to where it could still move? If it breaks at the back, it won't move but might run, and if it broke at the front, the cam wouldn't spin and wouldn't run at all. Would it be able to run if it broke in the middle? Does it start back up once you cut it off?

My guess is maybe pistons or rods.

I was thinking somewhere in the middle, who knows. It was merely a speculation. Did you notice the oil leak coming from the front crank seal? That's another reason I speculated crankshaft, but like I said...

I would like to know my self. First 6.7 I heard that sounded that bad.

Massive crankcase pressure from holed pistons?

That's almost as loud as my 7.3... lol.

I'm curious to what could be the problem as well. Back to where the break is, are they running the cam gear off the front of the crank? Not like they have been running them on the back of the 6.4 and 6.0?

HAAAAAAAAAAAAAAAAA crank play! LOL

Sorry couldn't help my self

Back on track, you guys tearing the motor down or just tossing in a new one?

 

[dentexpowerstroke]

Still within ford tolerances I'd imagine haha

 

[ghohouston]

I should elaborate, at our yard, we have 4 shops, one for boom/bucket trucks, two for dump/haul/medium duty trucks/equipment, and a ford shop. I used to work in the ford shop, but now work on the big trucks. I was just more so posting this video for thoughts, but yes, they will be tearing into the motor since its out of warranty.
