02 426 yzf is leaking coolant from head

That tube with the o-ring the slips into the top front

center area of the head, thats held in to the motor by

one tab with a 8mm bolt.. thats where I have collant leaking from. Do you guys thing its just a bad o-ring or could I have a bad gasket or something even more serious?

I'm going to try a new o-ring first and see what happens, just curious if anyone else ever saw this or had this happen to their old 426?
