The idea is to entice warm air down into the tube.
A simple hole or slot would be fine as a pressure relief but probably not as efficient.

Not banned as far as I know....he used to post on a lot of different forums around the net, and seemed to disappear from all of them about the same time. He had a lot of good stuff to say.

Paul,
It might well be that George simply got sick of all the inane political correctness and subsequent over zealous censoring, particularly on VansAirforce.
George liked to dish it out and he was totally intolerant of fools so he could be quite curt at times....but in his defence he was also prepared to cop it on the chin as well. He just seemed to revel in the argy bargy.
Aaaah history has a way of redefining itself. One year you're a troublemaker and social misfit.......the next year you're a sorely missed font of greater knowledge.

George
I for one learned a ton from George. He was one who would spend 1/2hr typing a reply with clips to articles and research all the time. He didnt know me from Adam, and donated his free time to helping me and countless others here....yes even when I asked really stupid questions.
I did read under his handle here awhile back that he was BANNED. That is unfortunate, I know this is a business and has rules...but he was a great character.
Wish he was still here, hope he is well and enjoying life. I respect those that just put it all out there and dont worry about treading carefully and playing by the rules everyday. Thats just kind of cool.

I just hope
his absence is by choice and not some misfortune such as health or accident. His dissertations often were very informative and interesting, maybe even acidic!
Happy New Year to George and all the other RVer's.

George has not been banned from VAF, he posted as recently as last September. His account is still active.

I agree with this...that guy was worth his weight in gold.
I think it's refreshing to see different personalities come out in these forums. If we over-do the political-correctness, then I think we start losing site of what identifies us as individuals. There's a lot more that could be said about this topic, but I'm already guilty of drifting away from the "whistle slot" topic!
Speaking of which, I just drilled a single #30 hole about 5 inches from the bottom and called it good. I do notice oil on the end of the tube quite often and wonder if that's normal.

That can depend on how much oil you put in. Although my Lyc can hold 8 quarts, it likes to blow some out, if it's over 6. Many others do the same.

Thanks for the fast reply, Larry...I only put in 6 at oil changes. I learned my lesson early on!

Why no wistle hole on an RV?
A little late to this discussion but maybe some in-site will still be helpful.
Years ago their was AD's issued on some aircraft that didn't have them. If I remember correctly, every one of these had crank case vent tubes that penetrated the cowl with the end of the tube out in the (cold) airstream.
As we now know this is a bad thing...moisture in the vented gases condenses in the cold (out in the air stream) end of the tube and freezes blocking the tube. End result could be a blown out crankshaft seal and loss of engine oil.
Correct me if I am wrong but I am pretty sure their are type certificated airplanes flying around right now (legally) that have no whistle hole. Because their vent tube outlet is not in the cold airstream.
Most RV's ever built have had the vent tube exit point within the area of the cowling airflow and as a result do not have a whistle hole.
