I know the pictures aren't that good Sorry about that, but I took a lot and these were the best.

Both cracks go all the way around the tensioner but in very strange directions. Like a windshield crack does. As I look at it no wonder these things pop chunks off. I have a GM one on the way so a side by side may be nice.
