These are photos before the soak. Side view let's you see the amount of carbon on the piston really well. The mount of oil getting past the rings was actually loosening some of the carbon and it was actually smearing on the cylinder wall on some. The before photos of straight on did not show the extent of carbon. Just looked like a black piston.

After the soak and initial easy drive with the berryman still in the oil. About a half hour run time never going over 2200 rpm. The piston is nearly completely clean. Can actually read the numbers on the piston.

Cylinder wall at 156k still has really good crosshatch.

Flushing the oil circuit out with new oil. Wanted to be sure I got as much contaminated oil out as possible.

Ignore the time stamps on the photos. The date was not set on the inspection camera.

I will post back with oil consumption results. So far this has eliminated a knock retard issue I was having. Oil greatly lowers octane in the chamber and my knock is gone completely so I'm going to assume oil consumption will greatly improve.
