Ya I understand that, it's just the other side has a tear in it too , 3 times as big. Isn't it the job of keepin out drit, dust , water and all that other crap form jamming up the piston and corroding the inside,only to leave more damage. I'm no mechanic by any means, and I might over thinking this, but while its off and on the bench I'd perfur to fix it now.
