Sounds like either HG or a head crack is leaking some coolant into a cylinder when you shut it off and the collant temp goes up and pressure in the system gets higher. Then you are fouled with coolant in that one cylinder at startup 'till you clear it. Pressure test would probably show a leak if it was done hot and long enough. It could be leaking a tiny amount at all times during running and burn it also. Obviously you do have an internal leak if there is coolant dripping out of the pipe, unless it is dripping from somewhere above and it just appears it is coming out of the crack...and the rough run at startup is another issue... but it sounds like you will pulling that head at some point in the future. Hope it is not the case, that you find an external leak but sounds like a bummer, as it sucks to have to go through that after only 11K.
