6.0 Blowing White Smoke, no other symptoms
I have a 2004 F250 with the 6.0. Just rolled around to 40,000 miles this week. Everything stock. Only mod is for high idle. A few weeks ago it started blowing white smoke when cold, more than the usual. I took it in and they found 2 fault codes, one was a general FICM code, and the other was a turbo underboost code. The FICM code was for out of date software so they reprogrammed it. Then they took off the entire intake and turbo and disassembled it to find that it was very sooted up. So they cleaned it and remounted it. I also had them do an oil change to synthetic 5W-40. Truck ran great up until a few days ago. Started smoking excessively and even have fluid dripping out of the exhaust, which clears up after driving for ten minutes or so. This morning I touched and sniffed the fluid. It had a consistency of water and was odorless. When I accelerated it blew a lot of the smoke then cleared up. When stopped again same thing and eventually dicipated by the time I got to my destination. When it blows the smoke it seems to be underpowered until the smoke clears up. When I got to work this morning I let it sit for an hour and went to check under the hood. No oil loss, no coolant loss. I'm stumped. Let me know your thoughts.
