Three extra PSI in the cooling system shouldn't cause a gasket to
leak - if the seals and hoses were that sensitive they would pop left
and right on people.
The bolt that is weeping might be a "wet" bolt, where the threads
have coolant on the other side - check the manual. If so, you should
only need to remove and reinstall that one bolt with some sealant on
the threads, or (if all else fails) a copper washer under the head.
Mitchell says 13 PSI and Autozone says 16 PSI - One of them is
probably right, but which one...? Tie breaker: Go ask Ford. ;-)
