Glad to hear you fixed the fuel leak.

On the coolant leak. Are you sure the coolant is coming out of the threaded hole?? If it is....why don't you just seal the threads on the valve cover hold down bolt that is in question.

If that fixes it you could just leave it or.....you could thread an allen set screw, with the threads sealed, down recessed in to the hole. Then put a shorter hold down bolt.
