There were several points in Banks' paper we should try out on car engines. (1) He states that Brightray is cheaper than Stellite and softer, thereby not being so likely to seat sinkage. I think we should try this out. (2) Are we sure we are working to the low limit on valve guide clearance ? (3) Are we trying Silchrome valve inserts on the aluminium head, also are we trying inserts fitted in by non-screwing. Rm. {William Robotham - Chief Engineer} | ||
