Couldn't tell you off the top of my head - but a significant amount more than that of a XU motor. The crown is massively thick in comparison and it has a very long skirt - to the point where the bottom of it basically kisses the oil squirter - it couldn't be any longer without fouling the squirters. Especially thick on the DW pistons around where the combustion bowl is - to be able to get enough meat to put up with the constant heat cycling.
