I tried a road draft tube on my 340 about Fifteen years ago and first race they
made me pull it right off!!

I guess it depends on the year of the car? What was the last year they used them, '66?
Anyhow, I thought about that after I posted that. Our car was a '71, so I guess it wouldn't have been legal, either.

Yikes! I are getting to be an old fart. I remember seeing cars on lifts that while running, you could see the smoke billowing out of the tube. I guess '66 was wishful thinking.
It's ironic though, the stuff that's allowed these days, and you show up with a draft tube and yer out!

Me to, for every stroke you could see a little puff of smoke from the draft tube. ed

I have tried several theories at the track and confirmed some of them on the dyno. Brake booster valves are not created equal. There is dyno proven power here if you work for it. Mine will suck the bottom of the pan up against the pickup. You have to "release" the vacuum for the oil to drain. Then you'll know your close!

As are PCV valves. . . . and you are very correct that you have to work for it.

Wade,
Please expand on your comment of "releasing the vacuum for the oil to drain".
