Anybody ever hear of an Ecotec head leaking water from the spark plug seat? I have a new 07 Ecotec head that is leaking from the seat on the first run. Is there any way to repair this?
Thank you
.... oh, don't tell me I'm the only one that read, ECO, and PROBLEM, here....

its your imagination......
NOTHING EVER FAILS ON AN ECO!!! That engine was designed and built at the hands of GOD!!!
But its possible the leak is coming from the casting plug in the spark plug valley, or maybe there is a crack.... IDK.
Repair. Pull the head, have it checked for cracks. (after pulling the casting plugs and resealing them)
