Thank you for the replies
I plan on doing a lot of reading here, to familiarize myself with the Powerstroke.
I was an aircraft mechanic in the Air Force, plus do all my own diesel and gas engine work, as well as manual transmissions.....pretty much have all the tools I need, plus a couple lathes, presses, drill presses, etc to make whatever I need.
I did my homework on the 6.0 prior to purchasing one.....it seems to definitely be an engine that requires a mechanically oriented person to keep up with the maintenance on, unless money is no object. I'll definitely be sticking with Motorcraft parts. Actually had to order the thermostat today, as the local Ford dealer was out of stock. I'll check at the Freightliner and International dealer for the flush.
The automatic transmission is the only area where I am out of my realm.....at least it is spotless, operates well, fluid is clean, no leaks....and I understand they are pretty much bulletproof unless you haul a lot of heavy trailers. I have the tuner, specifically to handle any CEL's after the egr delete....I don't plan on bumping up the power at all. My boat + trailer is 4500 lbs, relatively easy work for the truck.
I'll be digging into it over the Christmas weekend......I'll have all my parts in by then, and will go ahead and flush it the weekend before. I did plug in my scan tool to check the EOT and ECT when cold....in case a sensor was out of whack.....after cooling off for 9 hours, with a 46 degree outside air temp, the EOT was 59.4 F and the ECT was 56.8....so the sensors seem to be right on.
Basically it runs quite well right now......starts great when cold, no issues other than the 170 degree engine temp. (Which on the dash gauge shows in the bottom third of the normal scale.......)
