That would seem to be consistent with a piece of an injector coming off, like you said in your first post.

What was the reason given to think it was done by a valve?



EDIT: Better quit talking about a lawsuit, or the poor guy's thread will get shut down.

 

If valve struck piston --- it would have bent.

Off the top of my head.. without seeing an actual picture...

I am suspecting something left inside the combustion chamber.. a nut, bolt, etc.

A piece of something coming off... injector... etc. possible.. hmmmm

 

Did they replace any glow plugs?

 

One other question for you guys,

It seems that they remove the rocker assemblies when they remove the heads. They were off when I went to look at the damage. So I would imagine the also took them off when they did the head gaskets. Seems that there would be room for a mistake in reassembly of the heads that could cause the valve to hang up. (which is what they are claiming happened)???? Your knowlegeable thoughts on that?

 

Diplomacy is in order, bud... start with the dealer... and if that fails.. Ford...

 

After all the discussions from you guys, I will try and push the dealer a little harder to own up and work something out. I am sure it was something left in intake or some damage they missed after the EGR or head gasket fix.

Best to you all

 

please post picttures of the damage to the head, injector, piston, cylinder wall, glowplug and anything else.

also ask the dealer why they wont replace the head, a piston, a rod,an injector, a glowplug. that would really reduce the parts cost buy about 3k, and the labor would go about 1k.

just a thought.

 

I just want to remind you that no legal actions are to be discussed or sought, these are the Guidelines you agreed to when joining this forum. We are here to offer technical advice to your problem.


When the EGR cooler was replaced, did the dealer install a new oil cooler at the same time? The cylinder failure needs to be inspected more to determine if heat or a foreign object was the cause.

Now the problem, you openly admit admit using a engine modifier, this could have or may not have contributed to your problems. This falls under the Pay to Play rules. You cannot look the dealer straight in the face or Ford for that matter when using a device. Those of us that modify or use tuners, do so at our own expense.

I would start searching for a used engine if it were me. Modified the right way, you should have no more problems.

 

Same question ...........

 

also If possible would it be possibel to see a copy of the repair orders with the tech comments and parts used durring the repairs.
without any of the above its all just pure speculation.

 

If someone installed a 03-04 glow plug, they are about 1.7mm longer, if memory serves, and can hit the 04.5-07 pistons. Glow plug tip breaks off and causes carnage. If a valve hit a piston, you would almost certainly see a witness mark on the top of the piston. Did the dealer surface the heads? Measure the head thickness. If it is less than 3.74 inches, it has been surfaced and can cause valve to piston contact, but I dont think that is your issue. Where are you located? Thanks, and good luck

 

That is why I was persistantly asking. I have seen it happen before. The new ones are 1.2mm shorter.

 

I knew why you were asking, just wanted to enforce the reason you were asking so the OP would answer. And I didnt remember the length. Thanks

 

Thank you Matty. Sometimes I get lazy and don't always explain what I am looking for.

 

Soft piston (Broke)?? Soft piston would show marks. Maybe a super hard piston would break, Seen lots of valves hit pistons never seen one that didn't leave a witness mark that part of the dealers story doesn't make sense. Also I think chezit is right can' they change 1 rod and piston and clyinder head? Sounds like a case of CYA.
