[QUOTE="Ruger, post: 1320754, member: 1594"] After consulting with several mechanically oriented friends (I thought I was among them!) and a knowledgeable guy at the Ford dealership parts desk, my suspicion is that I've been over-torqueing the bolts. Doing so may have simply put more pressure on the o-ring than it could handle, may have caused the thermostat housing (AKA water outlet, AKA gooseneck) to deform due to excessive pressure, and/or may have caused the gooseneck to deform due to too much heat being directly conducted to it via metal-to-metal contact with the engine block. So I have in my hands a new Ford thermostat gasket (P/N F1VY-8255-A, cost $8.82), and I have a new Ford gooseneck on order. We'll see... [/QUOTE]
