Not looking to argue the point, just presenting some information that I found that sounds logical and stating what I believe. This isn't much different than our political elections is it? 50% believe the world should be red and 49% believe the world should be blue and 1% don't have a clue. So whose belief is right???
I am in agreement with Alvin, if your lifters are clattering, then replace your lifters, no bottle of snake oil is going to replace worn metal parts, in spite of what Paul Harvey promised.
