| tappets to make them noisy? Is it wear on the bottom tappets, poppet valve sticking or insufficient oil supply? We are strengthening up the damper flange to stop oil leaks. We had SpectreCodename for Phantom III 11 on the track last week in exactly the same condition as your car, it lapped at 85.1 M.P.H and then put a con rod through the bottom half while trying a lap with the silencer cut out. It looks as if the exhaust system is worth about 4 M.P.H. Yours is worse because the design omitted a few holes by mistake. 2/G10 has gone over with E and will be ready to run at Chateauroux in about three weeks. It will be a useful stand by in case of major SpectreCodename for Phantom III failures. Is SpectreCodename for Phantom III Clutch giving trouble when lined with Bog & Beck material?
