Lower pully seals can be weepy like mine , rear subframes can rust out , my engine has done about 80 thou and is just fine only had the ac cluch fail and the and the alt belt guide pully bearing done and you can get a clutch for £160 , bit hard to work on , and its not a bad idear to clean out the upper and lower manafolds every few years as the EGR dumps a lot of crap in there.
