Did you recently topped off the coolant? I have the same problem where too much coolant will weep out the overflow by the cap, even with 1:8 cap. Since it drains into the front downtube of the frame, it hits header.

I had that problem and it was the rad cap. Replaced with a new one and problem was solved.

Unless like MX813 stated, you filled the rad up too high.
