confused the crap outa me, I think 'dump valve' and I think about the
thingy in the manifold or a turbo engine rather than the little rubber
wossit in the bottom of the air filter box.
Is there such a valve in the heater box? spose there must be
considering the intake is open-upwards allowing rain straight in.
I'll piss-off now and do something useful....
