Oil cooler location
A friend of mine is going through diesel training and told me the probable cause for my EGR valve and cooler clogging could be my oil cooler being clogged and my turbo having carbon build up. Is this possible and if so where is my oil cooler located and what is the best way to clean it and my turbo? Any help would be cool.
Thanks Tom

Many people blame the egr/egr cooler. In reality the oil cooler fails, plugs up, and causes the egr cooler to over heat and fail. They replace the problem and eliminate the messenger. Bad choice in my op.

Hmmm, I hesitate to post this hypothesis...
Is it possible that the reason the oil cooler is clogging might be due to the exposure of exhaust passing through an exhaust cooler, i.e. the egr cooler, which could be super heating the coolant and damaging the coolant? It has been suggested that this exposure may be contributing to the drop out of solids and goo within the coolant. If this is accurate, then could it be possible that the EGR cooler is causing the oil cooler to clog, which causes the EGR cooler to fail?

Chicken or Egg. This is fun. Go fella's. This is anything but boring to we 6.0L fans. Do we watch the ECT vs EOT delta to tell us when to replace the oil cooler or.........

Some have also speculated that the clogging was from silicate drop out in the Ford Premium Gold and have changed coolants. Yet some have gone a 100,000 miles plus on the gold with no problems. Some have also found casting sand in the cooling system. Myself being one of the later. I have installed a coolant filter as a pre-emptive measure. Some have not and had no problems. I for one believe in leaving the system as designed and do the pre-emptive items to include maintenance that is more stringent than Ford requires. I like to think that a direct result of this is the reason that my truck has never left me stranded anywhere.

Found mine in the bottomof this bucket when I drained a couple of gallons from the radiator:
When I was doing my coolant filter install:
It came out of the bottom of the radiator I guess. Drained about 2 1/2 gallons of coolant for the install. Sorta looked like metal shavings but a magnet wouldn't pick it up so I'm saying it's sand.

No plugging yet (as far as I can tell) pulling filter this weekend. Pulled a camper the 4th weekend first time with filter and SGII. Temps were high 225/235 pulling hills. Going to clean outside of radiator, intercooler, and condenser while I'm in there. Temps and delta is ok unloaded.

In the spirit of speculation and an attempt to help dispel fact from fiction, the "casting" sand which everyone is finding. How do you know it's casting sand, was it tested? Is this casting sand really silicate fallout and not casting sand at all? Here's a favorite antifreeze article of mine with a great picture of silicate fallout which I could see being mistaken for casting sand. Again just in the spirit of speculation..... :-)
