I don't know of a good list, but I have learned a few things about the 2.5 engine:

-It's a real pain to change the timing belt on the DOHC 2.5 ('96-'98 or so) The single cam version of the 2.5 or the 2.2 should be easier

-Early 2.5s had head gasket problems ('96-'99?)

-The front crankshaft oil seal lasts just slightly longer than the timing belt.  Change it when you replace the timing belt or you'll be tearing thing apart again soon.
