Welp, I believe my deltas are far enough to go in and replace the oil cooler. While I am in there, I was going to delete the egr, do standpipes, dummy plugs, and stc fitting. Is there anything that yall suggest to replace or add while I am in /around that area?? Im going to IPRegr delete, and OEM oil cooler/gaskets/standpipes/dummyplug/stc fitting. Thanks for the suggestions!
