One of the last parts for inspection; the rockerbox. This is the part that contains the rockers, cams, camshaft and the bevel wheels that drive the cams via the vertical camshaft. Simply remove the rocker spindles and a few screws and the cover comes off. The rockers can now be withdrawn and the oil seals removed.
The cams and camshaft are left in situ; everything looks fine and well oiled. The tunnel that contains the cams is in perfect shape; this is the part that is sometimes smashed in worn engines, resulting in excessive oil leaks (I'm quoting George Cohen here). The 'ear' at the inlet side has been welded; it looks like a repair well done, no cracks visible. No signs of excessive wear except for the rocker spindles that show some marks where they rubbed against the rocker-rollers. I'll see if I can get replacements for the spindles, new seals, clean it all up and fit it back together again.
