I have been watching how this truck has progressed from the day I bought it and Every 3K I have had the oil sampled. Only mechanical failure I have had was a radiator the blew out on me coming home from a trip out west. That failure has begun to leave me to believe I have a bigger issue going on then just a fluke Radiator as by what I have been seeing in the UOA's. I had thought from day one by what I could smell after a good run that a hint of a-freeze was noted. No tale tell signs of issues except for the UOA. There are only four places I know how A-Freeze can get into Oil, Turbo, HG's EGR or worse case cracked block or head. Anyway I wanted to get a couple of third party Interpretations of the UOA from the members here to see if my concerns were legit. Thanks for this site and the p[oeple who keep it alive.
