I'm pretty sure that I won't be using this piston again. Temped to pull out the offending matter and apply some bondo to see how that works.
Something new to hang on my wall.
I did notice that the top ring is stuck in the groove and not making contact with the cylinder wall. I will order a new piston, get the rod checked out, and then all new rings for the other three pistons.
Some good news... kind of. If the valve was not introduced to the piston, I would not have noticed that the heat from the turbo was melting some plastic bits on the passenger wheel well. It you look through the little hole on the large melted plastic piece you will see a white tube. That's the fuel line.
Heat shield is in order!

For those of you playing the home game, here is a little more turbo action for you. Assuming that the tune is stock, this is running around 17psi of boost. Not too bad for something that has a 17.5 to 1 compression ratio.
The 444 cubic inch engine has been great over the years.... let's see, carry the two, divide by infinity, and I come up with 7.3 liters of stump pulling power out of the old 2001 F250. Today's trucks will blow away the power numbers of my old work horse, but since it still looks pretty modern, looks nice, and it quite functional, I started addressing some of the issues.
When I got on the throttle, there would be a cloud of oil smoke behind the truck. To avoid the smoke and oil spray out the back when towing the trailer/car, I would slow down while going up hills to stay out of the high RPMs. A buddy (Dana) took on the task of addressing the oil leak.
My understanding was the oil was coming from the turbo pedestal so I ordered the four O-rings from
http://www.dieselorings.com (funny that they have my exact truck on their home page). When Dana got into it, he discovered the oil was actually coming from the EBPV actuator on the pedestal that controlled the warm up valve; closes the valve to help the engine warm up quicker. [EBPV - exhaust back pressure valve).
Turbo with the valve.....
Actuator with obvious oil leak around the EBPV....
Removed all the EBPV parts.....
Sealed the pedestal....
No more valve....
Next.... the fuel tank!
