Do these lobes look OK? None of them are rounded, but they all have the same wear pattern. Cam has 700 miles and 40 or so passes.

The "shiney" area on the nose of the lobe is shinier and wider than Ive seen on my other used cams..fwiw.

Get out your mic and measure the lobes top and sides see how much wear you have
I think unless a cam is extremely low duration that's not possible by directly micing the cam. With the lobe at 12 o'clock the 3 and 9 positions are well off base circle.
A person could measure the lift with the cam still in a block very accurately though.
Besides, virtually ANY measurable wear is a bad cam, as once it starts to go it goes very fast, and usually looks pretty ugly (scoring, galling) in the process.

when i measure cams, i use two blocks of wood with 'v' cuts in them and bolt on a degree wheel, using dial indicator to measure from lobe to lobe. magentic base on a steel bench, altho i have used just a plate to mount the base.
It may be ugly, but it sure is slow.
