Found this bucket while disassembling an 2008 CL65 with a M156 motor... the engine was undergoing a renewal of camshafts and hydraulic buckets due to a pre-existing factory defects with the cams and buckets.

Obviously the bucket will be renewed but take a close look at the top of the valve stem that utilized this bucket... the head is rounded. Can this be used, as is, or does the cylinder head need to be pulled and the valve renewed?
