i think larry just meant he did not like reusing used pistons.

and while that is a valid position, i have used the old ones on at least three mb diesels and know of a couple more with success. the pistons have to be examined and measured for excessive wear by someone who knows what they are doing (not me, my machinist). on some of my engines we had a piston or two that did not measure up and had to find other pistons. we used pistons from another engine or two that i have laying about that did measure up.
