working on fords for 20 years ive seen the same in the plug holes on most cars even ones a few years old. rust,dust, corrosion etc. (the climate we all live in is way hot then way cold ,damp many months, its normal) as long as you got the plus out ,cleaned the holes and used a little dye electric grease on install its fine.
