That plumbing back to the intake is standard. It is also "standard" (per
one of Murphey's laws) that the rubber hose will harden with age, then crack
and leak, causing BIG vacuum leak and rough running until you find the
problem.
Looks like everyone missed ___?'s feedback - told how he'd used a clear
plastic line that had a drain valve on end - he'd collect a bit of oil and
drain it. Then he put a smaller piece of tubing on the engine and put its
"bottom/open" end inside the original/larger dia tube (which was no longer
hooked up to the engine at top, just open to the air) and never had any more
oil show up - the engine was able to "breath" in the space between the walls
of the two tubes. I think folks should try to duplicate his results and
hope that can be the "standard".

I was under the hood of my Mom's Ford today. I took notice that the
vent was plumbed back to the intake after the throttle. I'd never have
thought about it except for this thread.
Why wouldn't you plumb it back to the intake since it is a low pressure
area (post throttle), and it'll never make a mess there since it'll get
pulled back in and burned?
