Not quite, while you have prevented the coolant from being dumped into the cylinders and blowing your headgaskets, you have not stopped the cause of a clogged oil cooler and breaking down the oil from overheating.
You have two options, first moniter your ECT/EOT temps and rebuild the oil cooler (kit from Ford runs around $200) everytime the delta gets around 15*. Second, conduct a complete coolant flush with Restore (removes silicate deposits), then Restore Plus/VC-9 (removes the scaling and junk) rebuild that oil cooler post-flush, pre-fill and fill that system with a silicate-free ELC. (Ex: CAT EC1 rated)
Removing the silicates from the coolant is the only way to ensure you don't plug the cooler up. The EGR delete, just prevents the coolant from getting in the intake with everything lets go.
