Im in the same boat as you Powerstroke.I have been shopping the job in the New Orleans area to change the oil cooler and install my EGR delete kit and have gotten quotes that range from 540.00 to 1030.00.They are saying 10-13 hours.Im thinking I can do it myself.I swapped my turbo out myself and it doesnt look like the oil cooler and EGR coler are much deeper than the turbo.looks like its just the next layer of stuff to take off.
