problems caused by bad motor mounts

i know some of the problems bad mounts can cause but feel free to throw in your knowledge on the subject,thanks

Exhaust leaks, "rough idle", power steering lines crushed, cracked oil pan. I also believe my bad motor mounts caused enough stress on the tailshaft of the trans where its mounted to crack it. If my day goes as planned, I will be dropping the K-member on mine tomorrow to replace both mounts. I will document this procedure with photo's.
