BSA B31: Strange oil leak from Timing case

[briancairns]

I believe Derek is refering to the alloy plug circled in red which was fitted after BSA machined the oilway to the quill.

No , My casing definitely does not have that...1954 BSA plunger

They all have it Brian, even my 1948 B32. It's a necessary part of the manufacturing process but if your's is more or less invisible it's probably not the source of the leak.

Apologies, ok thanks.

cheers

Brian, Sounds like you have cured the problem. Well done. Perhaps the pop you heard was a dead rat being expelled from your pipe? Now get out there and give it a damned good thrashing, just to settle things in.
