Pistons ok or not
So I had to take off the head because I've got 3 exhaust valves that have pieces broke off. Well taking off the head I can now seeno have nicks in the top of two of the pistons. I'm getting a full valve job done in the head but should I tear apart more and replace the pistons and if so only the one really beat up one, both with nicks, or all of them. It's a justa 2010 engine so no big power with 120k miles. Cylinder walls are still perfect.
