I know the owner of this car very well, and should like to write and ask him how he has managed to wear his cylinder bores in such a short space of time. Before doing so perhaps you will let me know what you have told him, whether you have asked him to run on special oil, and who paid for the rebore. By answering this, I shall not be putting my foot into anything. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
