MessageThat's correct. The whistle cut should be inside the engine compartment. Mine is about 6 inches from the bottom
of the cowling. I don't think there would be an icing problem there. And if there is, I'm landing, right now!!! cause
it is WAY too cold outside. (;<)))
The angle cut at the bottom of the cowl/fuselage (mine is 1/2" aluminum tube) sticks out about an inch or a bit more.

Ronnie,
Thanks for your response. <cut on the piece that sticks out the bottom> - Bottom of the cowling? Shouldn't the whistle
slot be near the opening of the crankcase so the potential ice blockage would be down line?
The angle cut is a good idea. Some have wrapped a spring around the middle of the slot also.
Paul

I used the whistle slot and it works fine, IF you have a good rearward cut on the piece that sticks out the bottom. I
tried cutting it more in line with the fuselage bottom, and that caused oil to blow onto the firewall through the
whistle slot. I recut it with more angle and it is working fine without getting oil on the firewall.

Because of the possibility of the crankcase breather hose freezing up, reflectorites have suggested slitting the top
side of the hose near the crankcase outlet for pressure relief in such an event. This avoids blowing out the crankcase
seal with a blocked hose.
Has anyone considered/used a pop off valve in the hose instead of a slit? Seems like this would give a more reliable,
controlled escape. If so,where would one get such a valve?
