everywhere that has a gasket or o-ring...replace it. i had to deal with the oil thermostat for oil cooler o-ring becoming hard over the years and dumping oil. the material they use now i think is different so late model's don't seem to have that issue. still a good idea to replace a 50 cent o-ring regardless since the motor is apart. if you want a perfect engine, you'll want to replace cam adjusters as well, and inspect lifters and camshafts for wear. head bolts as well.
