As I wrote in the first post D.elgin fixed both the cam and the lifters. What I am talking about here is doing a slight resurfacing using a 220 grit paper doing eight movement to make sure they are rubbed evenly.
This is what D.elgin told me. Still that wont probably make the lifters rotate, just get them back to the starting point from before the breakin.
That is true for most modern push rod engines. But the straight 8 had flat lifters and flat cam lobes. There was no slope on the cam lobe.I have always understood that the lifters have a symmetrical convex curve on the bottom that is surface hardened for better(longer) wear and the lobes of the cam are not at 90 to the sides but slope one direction to spin the lifters, also to prolong wear, as the cam doesnt rub the whole face of the lifter(less friction as well)Confirm? Deny? I wonder, if these are hardened surfaces, how you are expected to fix the cam they were supposed to repair themselves after you paid them to do it, by hand sanding hardened machined precision surfaces. Just Sayin'?
