The only real way to test this is to place a new seal in some solution and come back after a few months to see whats happened. My guess would be not much. In my experience seal corrosion is mainly because of an owners inattention to basic maintenance. i flush the coolant about once a year while some people dont believe you ever have to, they just keep topping it up when it seems low, which is a terrible practice.

I would do this immediately as I have a friend that did it and the RedLine ate into the seals and destroyed them in a matter of hours.

However, You would not want to use new seals, you would want to use old used seals as they have been bombarded with hydrocarbons and assembly lube etc etc and would more accurately represent seals in the engine.

I'd be suspicious of anyone recommending to put ANY Ford part into my cars.-Ted
