Yes the crack is hair line i had filled the little wel with water and to my dissapointment it disappeared before my eyes. The mechanic had sugested to put aluminum boding agent to seal it. Yes is this another concern i should be concerned about? Shoulf the raditor be flush or what?

Still cant see the crack just a spec on the expansion / casting plug. is that where it is leaking. make sure you change the oil and filter before you run it again. The water in the oil will close the pores in the paper oil filter.
