Here are the pics of the two different tensioners. The broken unit came from the failed 3.2, the intact unit came from a 1998 2.5 Boxser engine.
Note the wear surface and the thickness of the tensioners.

It kind of hard to eye ball the thickness difference of the tensioners but I guess there is. I one thing I did see was the pot metal at the break. Those tensioners must be put under a tremendous amount of stress (I think of watching a motorcycle chain under power and then letting off) and to use crap metal is crazy.
So Jake, you think this could be the cause of some of the failures? Because of the carnage in a block after one lets loose that it simply is being overlooked and the blame is put on the IMS? If thats the case the fix seems so much easier to remedy.
