well I've herd a lot about the LIM gasket problems on a series II but i haven't herd much about the series 1. does it have the same problem? i was just wondering this because my bonnie has almost 160,000 miles on it and it has a series 1, no leaks or anything but i was wondering if i should expect it soon.

Yes it has the same problems. I replaced mine at 190K and wish I had done it sooner. Mine looked like "DANTHURS" picture in this thread.
