[Richard Coutts-Smith]

Been talking to another Aussy Humber owner who has a query:

"I suspect the valve guide seals on the vehicle are in poor shape. The Rolls manual on these engines seems to indicate that these are relatively easy to replace without removing the head. Are they rubber seals or something else?"


I note that the seal is referred to as an "0il Seal" in the workshop manual, and "Packing" in the spare parts book, and is on the inlet valve only?


It does appear (Rolls "B" Series Manual) that you can remove the inlet valve spring in situ, with the right tools to stop the valve dropping, but the Champ and Humber manuals both mention the oil seal replacement only with the head off.

Any one been down this path?
