What damage can a bad lifter do?

When a lifter goes bad, the inside section of these lifters can go all the way down to the point where they contact the camshaft. So, the roller on the lifter presses against the camshaft and can damage it to a point where your camshaft would need replacement in the next 10,000 to 15,000 miles.
