| -2- have been asked to instruct the works to fit LeC.3420 with .350" pipe replacing .500" pipe on all cars fitted with the new resonant air silencer. We are now carrying out further experiments on P.II. cars with a view to still further improving the oil consumption. Too much oil is being pumped out of the crankcase into the breather pipe, on one experiment the oil actually came over the top of a'18" pipe fitted vertically from the crankcase into the open atmosphere, and our job is to prevent this by some form of baffling or find a better place on the engine.
