I am doing some research on FORD vehicles that have cylinder head problems. It seems there is a design flaw with the spark plug holes(lack of threads) on several FORD vehicles from 1997-2004. It seems FORD has totally refused to acknowledge there is problem , and depending on the dealership help is slim to none. It seems the independnat repair shop are fixing and know more of what is happening. There is a class action law suit in California , but other than that I know of no other action against FORD. with 17 million vehicles effected, this could put the out.
