No, used ones, the lifters had about 10k miles on them. Makes it even stranger I would say. If it was to be a casting flaw, then you'd expect it to have shown in the first part of it's life.
I still think it's indeed a casting problem, maybe in combination with what Rhys sugested: a rotating lifter and a stationary pushrod.
The reason why it only showed now is because I used a different pushrod on the lifter which must have had a slighty different 'size'. Because of that some very little initial metal-wear-bits got loose and helped sanding it down further.
When I took out the lifter the hole was full of shiny metal bits. Which I think dramaticaly increased wear.
cheers, ben
