| 1245 W/P. Sr/VA. from Rm.{William Robotham - Chief Engineer} Rm{William Robotham - Chief Engineer}4/R.12.5.39. With reference to Sr/VA.7/ET.4.5.39., did you fit 'L' section rings to this engine when you fitted the pistons to EB.3151? If you did not, we are not surprised that the oil consumption has taken a little time to settle down. We should not suggest blocking up the oil hole in the connecting rod. We should like to know what the consumption is when the car has done 1500 or 2,000 miles. Rm.{William Robotham - Chief Engineer} | ||
