My 2004 Lariat 5.4l 3valve has a knock on the passenger side in the back. I think it is a bad lifter. Two questions. Can the valve cover be removed with out draining the AC? The book says that the AC needs to be drained so that the accumulator can be removed. On the 3 valve, can the lifters be removed after popping off the rocker with out removing the cam? What do I need to replace in the process of doing a replacement of a lifter (valve cover gasket-seals......anything or is everything but the lifter reusable? Ant suggestions?
Thanks for any help. I have been looking for answers and pictures but have found none.
