Piston Slap (knock)
I have a 1998 Ford Expediton with the 5.4L Engine. Last week my truck developed a very loud knock, only when the engine is cold. I understand this is a common problem with expeditons. Is ford doing something to correct the problem, like replacing engines? If not, what can I do to make this noise less noticeable. maybe, use a different oil. ANy suggestions you guys can give me will definetly help. By the way, my truck only has 75,000 miles. 
Thanks a Bunch!!!

Well, let me update you all on my situation. Since I didn't get any responses, I decided to go ahead and try to fix it myself.
I switched my truck over from Castrol GTX 10W-30 to Mobil-1 5W30 Full-synthetic. After I did that the knocking has completely dissappeard. So I hope this helps someone with my same problem!!
