In reply to your A/M3/S.27.10.25., with regard to the platinum tipped rocker arm of which the platinum has completely burnt away between three and four thousand miles, we have discussed this matter with EY. and EFC. who consider that it is probably due to the presence of too much oil vapour, and we therefore can only suggest replacing to A.T.D. account.
