coolant bubbling between head and intake...

cracked the head haven't I? Coolant and temp gauge were fine when I started, fifteen miles down the road (at my destination, after driving the speedlimit), gauge is rising precipitously and steam coming from underhood...

Now theres antifreeze percolating between the head and intake manifold

change the intake manifold gasket? also check coolant lines going to the IM

right on the money, thx. Intake manifold gasket was bombed.
