Re: F250: Dad, I found a shop just west of Dripping Springs called Malone Diesel. Here's their website: www.MaloneDiesel.com
. I read their "Tech Tips" and it is obvious that the guy knows his stuff, especially with Fords. I would call them and ask to speak to someone who knows the 6.0 engine well and then explain your situation to them. I suspect that they have seen that problem a hundred of times and may be a wealth of information. Using some aftermarket parts, they maybe able to get the truck to better than original so you can continue using it. Or maybe they'll tell to fix it as cheap as you can sell it. I don't know, but I bet they'll have an opinion and some suggestion.
Here's their phone number: 512-858-2132 Hours: Mon-Fri, 8a-5:30p.
I'll let you know if I find any other shops that look helpful. ”
