Oh but they can be installed...
Reilly,
Is there an automotive valve seal which will fit the Lycoming valve stems? I ask, because I know of another list member who was considering doing just that.

Interesting, my mechanic told me to order a set of valve stem oil seals for my next annual because the intake valves have a little oil leaking past them at low power. Perhaps I got my wires crossed somewhere.
Are stem seals a standard thing to fit to these engines or is it an experimental only application?
Can I just go out and buy them from a Lycoming engine overhaul shop?
