Pulled the head off 240, running B230f. It has some corrosion on the head. My question is, have water or oil jackets been sealed by corrosion?
Holes in new head gasket line up to corroded area. I poked with knife and its solid.
Any help or insights appreciated. This is the one im wondering about. 3rd hole? From bottom . Near intake valve. I put a black dot on it with a sharpie .
