If you can (not sure on that model coil pack but one f150) electric spray contact cleaner to dry it out and apply dielectric grease to keep it out, now if is or has access to your engine oil and needs a gasket which I do not know of then there must be another procedure to take.

Thanks, Mark this sounds like a plan. Certainly worth a shot.
