My ticking began with 17k on the truck. I took it to the dealer and had them make note of the problem. Of coarse they said it was normal and not to worry. Some of you suggested using 5w-20 oil to prevent ticking. I was due for another oil change so I used M1 Syn 5w-20. The ticking has quietened down a little but it is still there. The change of oil has helped but we still need to get to the root of the problem. Has anyone tried using different lifters or is thinking about doing so. I would if I had the extra cash but my Vegas trip is coming up soon! It's up to us to figure out this problem!
