Both me and my dad were told not to work on it at all by the person who did most of the work since she got it, and I haven't looked at it much so I don't know for sure, but...

I don't think the flywheel has a timing mark for the diesel on it, so that could certainly be a problem. The crank pulley wobbles a lot, but as far as I know it was put back together properly when the timing belt was done last, so its hopefully not getting any worse right now. I still haven't had the opportunity to take pictures of it at a time when its light enough to see anything, but I will post some this weekend.
