Us old folks recall the black stripe down the middle of highway lanes...when road draft tubes were commonplace, if not downright standard until pcvs came along.
The amount of wet vapors aren't going to cause much in the way of dampness on track.
As noted above, the
oil is routed back to the pan.
There was actually a line all the way back to the rearend, which had a T off to the trans, and then up to the tank. Generally speaking, given the uphill and lengthy nature of the rearend/trans tubing, only vapors made there way to the tank itself.
Mine is hooked up that way as delivered by Da Boys. The tank was the only breather I ran for the first couple of years. I added valve cover breathers later, but not really because I needed them...the old school setup works just fine.
