Re: 2004 engine tapping sound
Hold it!!! I just found a TSB for this!!! It was issued by Ford on October 18, 2004. TSB # 04-20-8- you have to remove the front valve cover, rotate the engine around until the #6 intake cam lobes are pointing up, then remove all of the intake camshaft caps, reinstall them and torque them in sequence to 72 lb-in of torque. The sequence is the first cap, marked 5L the front bolt first, then the rear bolt; next cap is 6L, front bolt first then the rear; 7L is next, front first then rear; then 8L, front first then rear; then lastly, 9L, front first then rear. If your still under warranty have the Ford or Lincoln Mercury Dealer do it. If you do happen to do it youself you cannot simply loosen the bolts and re-tighten the bolts. They have to be fully removed according to the TSB. Good Luck!!!!!!
