[QUOTE="WVUAnt, post: 6493802, member: 52472"] It is primarily a cold start issue. Yes, it is common on 5.4 2V motors, and even some 3v. The noise does go away and does not present any long term problems for the motor. My 99 has had the knocking problem since new. It was covered under a TSB...cant remember the code, and the engine was replaced. I do remember that the TSB was very specific with dates of manufacture listed. The replacement motor knocks as well. The knock goes away when the engine is warm or when you shift the tranny into drive. The noise I think is officially called a spark knock. Using 5W20 and synthetic blend, along with an FL820S Motorcraft filter helps. There are a ton (including my own) of knocking or ticking motors with well over 100,000 miles on them. [/QUOTE]
