I was checking my oil and coolant, (I've got a small oil leak somewhere, and recently fixed a coolant leak), when i noticed a small crack on the front of my head. It looks like maybe the engine was pulled using the stud and it stressed this area, causing a crack. Is this somethin to worry about? Should I put some jb on it or something to try and keep the crack from spreading?
The crack is directly above the pulley in this picture, below the valve cover and to the left of the stud.
Close up of the crack. It doesn't look like a load bearing area, so I dont want to be over-concerned.
