How often do you need access to the piston on a modern boxer? I'm aware of one where the piston disintegrated at 180K miles. The solution to that problem was a salvage engine that was only 25K miles old. Much cheaper than trying to fix the old engine.

So, are the cams only supported right in the middle with the ends sticking out into space? Maybe I'm missing something, but that pic doesn't look right. Also, I wonder what that big boss on the outside-center of the head with the hole in it is for?
