I just stripped down an M112 from a 2002 CLK that somebody managed to swap ML rockers into and "blew up" the motor he said. It does look like there are clean spots on the pistons from a valve strike.

Questions...
1. Is this a plausible story?
2. Is there any value to all the bits and pieces I just unbolted (heads, cams, pistons, front cover)?
3. Do these M112 & M113 engines suffer from the same head bolt ills of the M117 alloy blocks? (do they need helicoils much; special fitting for drilling holes)? Which is to ask, is this block a large paperweight?
