Triumph 6 cyl. valve stem seals

["H. Schoonhoff" <8gees@wxs.nl>]

In the August issue of Practical Classics I read about fitting small
rubber valve stem seals from a BMC A-series engine to a Triumph 4
cylinder. Does anybody knows if these also fit on the 2L 6 cylinder? Did
perhaps someone fit  other valve stem seals ? What are your experiences?

If I fit an extra oilfeed, I'll certainly need valve stem seals to keep
oil consumption under control.

Your reactions please.

Thanks,   Huib.
