90% of the time you don't have to do anything to a Ford 6.0 to be able to keep driving it, but as you add power you are going to have to spend some money. 10 grand sounds about right if you have a shop do all the work on the engine for you.A guy I work with just got his 6.0 redone to "bullet proof".
Cost him 10 grand........
Correct! This is why I asked the questions I did earlier to the OP. I have owned a 6.0 for years and they have their challenges but there are some regular maintenance tricks you can keep up on to avoid problems. It does become tedious but is better than dumping 10k unless you have that money at your disposal. At a minimum delete or upgrade the EGR because that is the biggest defect IMO and has the biggest potential to cause catastrophic failure. If you have a cold start (which the 6.0 will eventually have) the first thing to test is the FICM. If that checks out your problem is likely sticky injectors. They can be treated without replacing (very expensive) if the truck warms up and runs right.
The truck is running excellent right now actually. Just broke 100k on it. I bought it from a old farmer up in Twin falls, Idaho who was the original owner. New FICM is on it, as well as an EGT gauge.How is the truck running now and how many miles on it? Do you have a cold start issue?
