So check this out, if you leave hemi tick without treating it knowing what we know now, what do you think the temps are in that spot? The heat in the lifter will go right down to the roller. So what happens when metal is hot, much easier to damage, much easier to cut, mold whatever. If you stop that tick, one would think the temps in that spot would have to be cooler then if it ticked. I still think it would be north of 212f, because there is so little flow there, but whatever the temps I'm sure the lifter is less temp if it isn't in a tick condition. Another reason that if you can stop tick with lubrication or additive, you would be crazy not to. Same thing with cam lob, that sucker is flying around, if everytime it hits the roller and there is resistance which uncle tony showed us, then how much hotter must that cam lob get then a cam lob that has no resistance? I bet temperature is a huge part to these cut lobs.
