I worked at Freightliner for 20 years and never once saw them try and pull a fast one on a customer. You want to call the Detroit representative and ask him to look into it. Call him and fax the bill and everything else you have on the original repair to him,and give him the location of the unit.
Thanks for all the input, the head and all parts were new, there was no reman parts here and all were OEM Detroit parts. They are claiming the top outside of the piston came loose and caused the valve that broke off. The valve stem is in the head, and they now want to send the head and piston out to Detroit for their verdict. But I have to pay the shipping of $800 to do it they or detroit won't cover it. This is why O/O and Companies go out of business. I figured it out, the truck has less than 3000 miles since they put the new head on, and has less than 240,000 on a rebuild. The Rebuild was done by a noname shop, working on getting paperwork (before my ownership) and was done in 1998, I'm sure it was Detroit parts but it still makes no sense. The other cylinders look impeccable. I just hate fighting with shops to get them to stand behind anything they do.
Do you have any way to get me information on how to get ahold of a Detroit Rep? I would like that information.
Am I reading this right? It was rebuilt in 1998 and 240000 miles and 13 years later you want Detroit to stand behind a piston that may or may not have caused your problem? Your only hope is the head had a bad valve and they will cover the cost of another head, the 13 year old piston is gonna be your problem.
