sorry, could'nt resist. In the automotive industry it is completely inacceptable to use the term "bad" to describe a failed part. I have to pound it in to my technicians to keep them from using the term. B.A.R and G.M both do not like it. Every repair order has to have a compaint, cause of failure, and correction. Technicians like to try to use bad as a cause of failure. Example ( performed diagnosis for right front window will not roll up. Tested all powers and grounds to window motor and found "bad" window motor.) How about " tested all powers and grounds to window motor and found window motor has an internal open circuit." The word defective can be used but you still need to describe why on a repair order. So when they do this, I tell them "if the part is bad, try putting it in time out." |
Okay, my guess is the piston spring inside the lifter was beginning to fail thus causing less preload which in turn was causing the tapping noise.
