New to me 07 F350 crew 4x4, stock, fleet maintained (no towing) to 200k. Egr is leaking (it started buring anitfreeze out the exhaust and the driver stopped and had it towed in) reputable local diesel mechanic gave owner an estimate of $2400 (egr cooler and oil cooler) to fix it and the owner sold it to me as is. I have deleted egr, and replaced oil cooler on 6.0's with similar issues before and they are still on the road, but I just fixed those trucks and later sold them. At this point I plan on keeping this truck for a ranch truck, it will haul often and sometimes heavy. I will tune it but keep it mild, would like to get it up to similar levels with my stock 2012 6.7. I have rebuilt several 5.9 Cummins and worked on (rebuilt every major component multiple times) on Dodges for years but I have had a buddy come work on the 6.0's in the past so I have virtually no 6.0 experience. I'm not in the best shape anymore and pushing 40 but thinking of tackling this one myself, have a shop and tools but no lift. I am trying to decide between doing EGR delete/oil cooler/updates/tow tune/exhaust (custom SCT), or to do full bulletproof with studs and gaskets along with above. It will be a second or third truck so not the end of the world if I do blow a head gasket later, I can fix it then, but once and done is nice too, just hard for me to put in the time to do head studs if I would be fine without them. I drive sensible and have never blown a stock head gasket or turbo etc with modded 5.9's and 7.3's in the past. Thanks for reading.
