Do aluminum heads or blocks ever crack? My honda car has a small leak from #1 cylinder into the water jacket. In hot weather, it blows the water out of the radiator and then overheats. Verified it with the leakage tester today. #1 and #2 both might actually be leaking. It's probably been doing this for a year, and not gotten any worse, which doesn't seem like how a head gasket leak would be. Of course I'll pull the head and take a look, but if the head gasket looks fine, should I be looking for a crack in the head or block? Seems difficult for aluminum to crack
