Changed the head gasket and put in head studs truck was running great prior to tear down but was pushing bubbles in the over flow. The replacement went smooth but now the truck doesn't have as much power and I have codes p000f, p0087, p0251, p1011, and p1012 all fuel codes. Is it possible that one of the tubes to injector is not sealing right, the truck runs smooth just not as much power. It is deleted and I run h and s on low. What is the best way to check it thanks in advance.

As long as everything is plugged back in correctly, you might want to pull the valve cover back off and check the injector tubes. Are you making any oil?

Can a connector tube cause motor to make oil? How does fuel get into oil from connector tube issue? Wouldn't this just cause a high fuel return rate?
