| To Hs{Lord Ernest Hives - Chair} from Mx{John H Maddocks - Chief Proving Officer} X3806. Mx{John H Maddocks - Chief Proving Officer}9/14.9.29 CENTRAL LUBRICATION SCHEME We find as a result of further testing of the oil pumps that we still get oil leaks which run down the passengers side of the dashboard. Although some little time ago we said we were fairly satisfied with the modifications that had been carried out to overcome this trouble, it does appear that conditions of high temperature and further running will cause leaks to develop.
