Bailey - Chief Engineer} /Cgh. {W Clough} 1/W.2.9.36, we recommend that we do not go over to close inlet valve clearances on all production cars, but put a small batch through to gain experience, as we have done in previous cases such as magnesium gearbox, etc. Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} | ||
