My brother in law that works as a mechanic at a Toyota dealership was telling me the same thing. When I replaced them all the last time I was told to buy Melon lifters. After running them for a few years, Now I had one that I could wiggle the push rod. Tightened it up, drove for 35 miles or so, started clicking, now I can wiggle the same push rod again. Come to think of it, the first set of lifters worked fine for 2 or 3 years! Thanks for the input.
