has to be orings. the HPO is blowing past the orings that seperate the HPO ports from the fuel ports in the head and being back fed into the fuel system through the rail in the head, under pressure, to the fuel bowl. my truck did this as well, it was the injector o rings

i would assume he means the amount of oil coming out of the spill spouts on the injectors, ie runnin with valve covers removed and visually verifying the oil coming out of the injector spill spouts
