None yet and none that I'm aware of, yet
I think the big thing about hurting pushrods is when they rub against the head or block and or won't drop down away from the adjusters when setting the valve lash cold, in other words pulling the pushrod up against the adjuster and seeing if it will drop down on it's own weight
Don't get me wrong, I have hurt more than one pushrod due to not preventing the problems that burn the tips ups
BTW, I do use Manton series 3, or better, only on all my Hi Po motors, street or strip
