All this blowby test talk with garbage bags (has anybody tried the Glad ForceFlex bags yet) and stuff got me to thinking, and I went to wallyworld and bought a sack of the party-whistles that both make a noise and 'roll-out' when they are blowed....maybe called party screamers or some sort. I found a nice sack of scooby-do whistles for a measley $1.89

I disconnected the crankcase vent and ducktaped the party whistle to the tube. At 1500 rpms the whistle was hardly blowin and only rolled out a almost imperceptible amount, but when I checked it with a micromenter it had actually unrolled a couple of thousandths....but that is insignificant I think.

At 2000 rpms the whistle begun to scream and unrolled, rolled, unrolled, rolled, and produced a fluctuating whistling sound that drew several of my neighbors over to see what was the matter. At full throttle the whistle shot off the hose and hit a woodpecker that was watchin from the sidelines. Luckily the bird survived the blow (they are endangered speci here) but he has a crooked bill. I don not know how that will affect his chances of survival, but he looked happy as he flew off.

I was almost embarrased but thankfully the wife was not home. Should the blowby present a consistent flow/pressure ? I could have sworn that the car was tryin to play that rupert holmes song 'escape' but it was probly just my imagination. I plan to try the spiderman whistles soon.
