| ( 8 ) Oil Filler. LOP. E.84983. Complete to above LOP. incorporating "Gaco" Sealing washer in oil filler cap. Supplied by Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} No trouble was experienced with the Gaco washer. Oil Level Indicator. LOP. E.8506 Lec.4352. Existing, complete to above LOP. & Scheme incorporating:- Lec.5067 Crankcase Vent. E.88197 Oil Level Indicator. Removed after 9500 miles and replaced by oil level indicator with special experimental cork float. This has covered 11.800 miles and shown no weakness. The indication of the oil level is particularly sensitive to variations of gradient and camber owing to the float being at the extreme rear of the sump. Allowance must be made for the oil to level out in the different sump partitions while filling, particularly when cold. It is very difficult to obtain an accurate oil consumption figure. Oil Temperature Regulator. LOP.E.86801 Lec.4871. New, complete to the above LOP. and scheme. Special strengthened cooler supplied by Rm{William Robotham - Chief Engineer}/Std. No trouble experienced. The maximum oil temperature out of the cooler recorded was 105°c with the water at 85°c. It did not normally exceed 95°c - 100°c. Ignition Distributor. LOP. D.75167. Lec.4950 & 5400. Ignition Distributors overhauled and re-fitted. Poor pick-up after the car had been left standing was experienced. This was due to the cam spindles sticking, which upset the working of the automatic advance governors. The trouble was less noticeable after running a little time, or the spindles could usually be freed by revving up the engine in neutral a few times. Examination showed that the top bearings of the cam spindles had received no oil, nor was there any possible way of oil reaching them from the lubricators. The spindles were rusty. The contact points were not disturbed or adjusted throughout the mileage, and there was no noticeable change in the gaps. No trouble was experienced with the distributor rotors.
