Bullet Proof Diesel is going to be your best for the EGR cooler, they make a bullet proof oil cooler but it is pricey, the best thing to do to save the oil cooler is to do a coolant flush and add a coolant filter. these blocks are sand cast and some of the casting sand sticks to the cast iron and will wear away in the cooling system and this sand is what cloggs the oil cooler up/tiny passages/ the coolant first goes through the oil cooler then through the egr cooler, 99.99% of the time the reason the egr cooler ruptures is because the oil cooler is clogged and not enough coolant gets to the egr cooler and the coolant will steam and rupture the cooler. Also when the oil cooler coolant passages get clogged the oil can also steam and rupture the oil side and when that happens you get oil in the degas bottle, that is why a Coolant Bypass System is mandatory on these trucks, International box trucks have coolant filters from the factory when using the same engine. I would do a Bullet proof EGR cooler/if you live in Cali, otherwise delete it/ A Ford factory oil cooler rebuild kit/ a coolant filter setup by any of the manufactures that make them, basically it comes down to what color of setup you like.
