Yep, I've pretty much come to the conclusion that I'm just going to fix what's broke, for now at least.  Definitely the balancer and maybe drop the pan and do the timing set, depending on how ambitious I want to get this winter.  Those Pacific Northwest winters in an uninsulated garage lying on a creeper on a cold concrete floor can be mighty tough.  Takes a lot of energy to get up off the couch after the kids go to bed and go dink around out there.
