David,
I
believe the "sniffle valve" on my IO550-G is simply a small orifice to which the
intake valve drains are attached. (when overpriming, fuel drains from this port
onto the ground). For the TSIO engines, a real "sniffle" valve is used. It is,
in fact a more complex - and more expensive- valve. Exactly how it works, and
which one Lancair stocks, I don't know, but there are two types. Hope this
sheds a little light on the subject.

All,
I am curious how the Sniffle valve on the
cont io550/tsio550 works.
It seems to be a check valve but if you are
normally asp
the manifold pressure would be less than
outside and if you are
turbocharged the manifold would be
higher.
This would mean a different valve in each
situation, yet
the lancair store only sells one part
number.
What is the story?
