Post a pic of the crack, normally they wont crack unless there is something in the way holding part of that cylinder up ad you torque it and POP!

is it the 6 or 4 cylinder?

the main thing that goes wrong with straight 6 having intake and exhaust right next to eachother is warping the head. Take it off and a good draw filing to check for flatness should tell you if its warped enough to break the intake.
