Fuel in coolant

[mdcody]

We have fuel in our coolant bottle. my question is do I have to replace the heads or can they be fixed? The truck has 200,000 miles on it.

If they are not too far out of specs they can be machined as long as they are not cracked.

They can't be fixed if it is the heads themselves. If it is an injector cup (rare) a new cup can be installed.

Ford does not acknowledge an injector cup as a possible cause of fuel in the coolant, the head cracks right above the cup

I figured it is heads cracking seems to be the problem always. Going to start tear down this week.
