As this site has helped me far more (computor wise) than I have returned, just wanted to say thank you and pass on some info that I received from a fellow member and a friend that I trust. Lets see if I can do it;
Have/had this noise on my wifes 96 Explorer 5.0. Now have to admit the engine noise is no where as bad as wifes cries, "fix my truck". You get the picture?
