Had a car dealer sold me a expedition with a 50% cost of major damage engine and transmission I had the coil packs and plugs changed. He took it to his mechanic and said a socket was shattered inside engine cylinder and then part of socket was lodged into a valve. He is definitely just getting out of paying his half of the rebuild is he not?

Hi and thanks for using 2CarPros. Com.

Wow. That is a tough one for me to answer. I have no knowledge of who you are dealing with. Who did the initial repairs? Did you discusses this with him/her? How much damage was actually done? Does the dealer giving you trouble have a reputation for not being honest?

There are so many variables to this. I have to be totally honest. If a socket got into the head, it has to be a really small one. The plug diameter where it threads into the head is only 12mm. It would have to be a 1/4" drive socket that is smaller than that, and hit just right. Plus, why would someone be using that small of a socket once the plug is out? I do not remember for sure, but I think the coil pack is held in by a 10mm bolt. However, once that is out, the coil is removed and a plug socket would be needed to remove the plug and not the 10mm. Once the plug is reinstalled, then the 10mm would be needed again, but the plug would be in and blocking the opening.

I am not sure what to tell you, but honestly, it does not make sense to me.

Let me know if you have other questions. I hope something I mentioned helps.

Take care,
Joe

Joe,

I sat and watched the guy change the coil packs and plugs, he used my small box of tools and all the tools is in it. It is a used vehicle but the dealer was going to have to pay 50% of cost off repairs on warranty. The piston would have busted before the socket was shattered into a 100 pieces right?

Most likely there would be piston damage. The more I think about it, something could have gotten through the intake if it was being worked on and nothing may have touched the piston. But rather, something got stuck in a valve.

If the problem existed prior to any repairs, I would think the dealer has the responsibility to do what he said. No one knew what was wrong prior to inspecting and trying to repair. Did you get the 50% agreement in writing?

Yes sir and there was no work done on the intake at all. All that was done was coil packs and plugs changed.

That is a tough one for me to say. If the problem existed prior to the purchase, and an agreement was discussed and in writing, I would feel he should help.

Thank you sir.

He is just trying to get out of it. I told him I will not pay another dime on it, if he thinks he can take it to court because "Ford company" has already emailed me and said the piston would have busted before the socket was shattered into a 100 pieces because, the socket is case hardened, the piston is cast aluminum.

Hi:

That is correct. However, remember that something may have entered through the intake. If that happened, chances are it may have never hit the piston. The problem is, we do not know what was done to the vehicle prior to your purchase. But, if you had an agreement and it is in writing, he needs to step up. It is obvious there was a problem prior to the purchase. It just was not diagnosed yet. This does not sound like you got a good running vehicle and then had a problem.

Did he tell you there is damage to the piston?

He said there was a small gauge in the piston, but he had the socket supposedly busted into 100 pieces. He tore it down without me being present. I am going to see my attorney in the morning. I am going let him if he is stupid and greedy enough to pay all the court fees, then I will get him in front of a judge and if need be appeal it to a higher court.
