Needing some advice, I have the opportunity to buy a 2015 Ford F250 Platinum 6.7L crewcab with a CP4 that’s bad in it. Doesn’t run. Has 130k on it. What do y’all think? Is there a step by step guide on this? If I can get the parts, I can do all the work. They are asking $25k for it. Appreciate any feedback.

Depending on how bad it is you'd need new injectors... you can cut the cost a bit by doing your own work but.... its a rats nest if you're not careful. I wouldn't take 25k for sure. You'd be talking more or less 10-15k if even. Thats just me. Are there any modifications done to it and any other info you can give us about the truck?

Private party value for this truck, which falls under the “rough condition” category, is $28,900 to $32,100. Subtract what the repair of the CP4 will cost and that’s what I’d offer. The average repair for a CP4 failure is about $14,000. Take that away from $30,000 and that’s what I’d offer.

$25,000 is way too high.

I wouldn’t pay more than $16,500ish.

There is a lot of great advice in this thread, but I think someone should create a step by step guide.

This is going to be just as common as buying a 6.0 with "blown head gaskets", because most people will diag this as a CP4 and see the number to fix it then just cut their losses.

@eric@cncfab it would be cool if you guys sold a kit.

Disaster kits are sold. Some are coming with the DCR option as well.

If someone said "doesn't run, its the cp4" that's a big red flag. Is it possible to negotiate a sales contract wherein you agree to a total price and subtract the cost of the repairs at an agreed upon shop? If you're looking at a cash purchase this might be a great option. You will get the truck at a reasonable price.

You would have to dig in for a couple hours to even verify the cp4 issue. You could end up finding more problems beyond that. What happens when the motor has a cylinder with low compression? In this scenario I would negotiate a price minus repairs with a floor price of $X. A new motor AND fuel system could eclipse the value of the truck so a floor would protect the seller and atleast give them scrap or part value in the deal. If they won't, let someone else gamble on that.

Cp4, rails, sensor, regulator, injectors, lines, tank flush, etc adds up quiiick just by itself.
