As new as I am to 6.0 problems I still can't justify spending that much time replacing a stock oil cooler only to have it clog in 57 miles and approximately 20 hrs later. I deleted egr. Flushed coolant. Ran zerex g05. So I got pissed off and assaulted my credit card for a BPD heavy duty w/cold climate. This better work. Im out of money lol. Worst part is, the guys at XDP say im probably the 3rd or 4th time they've heard that this month. Total waste of money.
