The oil cooler failing usually causes the EGR cooler to fail in most cases. And whether you have a EGR cooler that is blocked off or a full delete, it is recommended to have gauges/monitor to check the ECT and EOT delta so you can tell if the oil cooler is getting blocked up in the coolant passages even if you put in a new oil cooler and EGR cooler. You also need to install a coolant filter, and flush the coolant system, then switch to a ELC silicate free coolant.
The oil cooler gets blocked up and prevents the coolant from reaching the EGR cooler. When the EGR cooler is ran dry or with less coolant flow, the very hot exhaust gases (up to 1200*+) expand the thin walled exhaust tubing in the EGR cooler, then when you shut the truck down those exhaust tubes contract. Over time with them exhaust tubes expanding and contracting, will cause them to fail. Also with a lack of coolant flow thru the egr cooler, those hot exhaust gases can cause a flash boil of the coolant and over pressurize the coolant system, causing coolant to puke out the degas cap. Now if you were to block off or weld the ends of the EGR cooler, you prevent the hot exhaust gases from entering the EGR cooler. This will prevent/prolong any issues with the EGR cooler. If you goto Bullet Proof Diesels (BPD) web site and look at there EGR cooler and compare that to the stock EGR cooler, you will see that BPD's EGR cooler is made out of heavier walled and larger OD exhaust tubing.
If you need to be concerned about emissions, the better choice would be the BPD EGR cooler, or use the EGR spool plug that can be removed so you can put in the EGR valve prior to going thru emission testing. But if you do choose the spool plug or weld both ends, you might need a SCT with custom tunes so you don't get the CEL. Also you want to tie the EGR valve off to the side and leave it plugged into the electrical connector.
If you don't have concerns for emission testing, then the full EGR cooler delete is the better option.
