Well I'd think all one would need to do is pull the valve cover to fix this. That is if that us all that's wrong with it. I'd have to ask myself what went wrong to cause this. I don't imagine you will get off so lucky. It's been my experience with things that once one thing fails in a valvetrain other things will as a result. You will want to pull the injector and look down at the piston and see if the valve made contact with the piston. Best of luck to you man.
