Query: Unreliable

Started leaking within a month (under 1000 miles). Useless since now I may have to redo the seal and just wasted money on this... and no.. I did not overtighten the bolts as to have ripped the gasket. This is supposed to be a dry gasket which needed no additional sealant. I hope it works for someone else. And what's the O ring for anyways???
