Well that is how I read it as well. I don't see any missing valve Peices,a valve may have a crack from possible glow plug tip. That engine will get scrapped,I imagine the busted rings have destroyed the cyl, the head is junk. Now we all know where all the Peices had to travel thru. That surely can't be a pretty pic either.

 

That's what I'm thinking. The valve heads are intact. And whatever caused that damage was bouncing around the entire area of the piston head. The could have been a piece of valve head, but I don't see where a piece broke off.

Sure looks to me like either a GP tip or an injector tip.

 

Isn't this the actual broken valve? Look at the huge chunk missing out of it.

 

Looks like an oily spot to me, but if it is a missing piece then THAT would make sense.

 

Yeah, the dark part is the valve seat under the valve. You can see the edge of the valve where it is cracked is not aligned with the dark part.

 

The Dark spot is a broken valve.

 

Ah, got it. That's what I was missing, er, the missing piece.

 

Using the zoom feature we have now, I can see you are right.

 

Your correct. my failure not zooming up as well. well that explains it all now.I hope all works out well for you.

 

With all that damage to the top of the piston, I'm surprised how good the cylinder head looks. Would have expected it to be pretty dingged up too since it's AL.

 

Which head was it? Passenger or driver side?

 

Well I think that's the first insides of a pickup model engine I've seen...
I hope Ford gets this replaced soon for you.

 

Looks like the problem with cracked valves extends beyond the CC trucks. I wonder what the build date was on this PU?

 

And what were the conditions leading up to the failure? High revs? Temps? Or was it just a random part failure? If we know more of what was going on, we could mitigate our personal risk.

 

I think gathering build dates for these failures could be a good thing.see if there is a pattern, with possible defective valves. Or something else is causing this. But now a pickup kinda puts a different twist to it,than being in the chassis cabs.
