Is the provent or the other one shaped to where you could easily "vacuum" the fumes to the intake with a large hose? I'd like to make something that keeps the oil in the engine, AND sucks the fumes in to the intake. Reason being, I'm a severe asthmatic and can't breath with any exhaust or crank case fumes under the hood (enough always makes it in to the cab to cause me problems).

I know I could pipe it to the airbox, but then you're slowing losing oil, which is lame.

That is exactly what the Provent system does, it filters out the liquid oil using centrifugal force and a internal coalescing filter which then allows the liquid to drain out of the bottom of the filter housing into a drain tube and the fumes are returned to the intake boot to be consumed by the motor (a closed system). The drain tube can be routed back into the motor as some on this list have opted to do that, does require some extra work. On mine, I simply routed the drain line to underneath the vehicle and put a small valve so that I can drain out the liquid about once a month. Filter does a very good job and no fumes, vapors, or smoke from CCV!!!!

Wow, and I made the silly assumption that they vented to the atmosphere! I would have bought one a year ago if I'd have known this. Many thanks WW!
I haven't seen any write-ups about how anyone routed the oil back into the crankcase. Do they tap a hole in the valve cover?

And the intake el would have never, ever, ever broke from heat and the stress of movement at that point had it not been for the oil?

I periodically drain my Provent drain line that is routed down below the engine compartment and fitted with a small drain valve. In cold weather when I open the drain valve I get a small slug of water from crankcase vapor condensation followed by oil. I'd rather not have that water put back into my oil pan.

I agree. A fair amount of condensation accumulates that I would rather not route into the oil. On an OTR truck that runs all day and the oil stays hot enough to keep the oil free of water I can see tapping it into the oil pan, but on a daily driver? No. I got a small drain valve and when I see the clear hose is getting full I dump it in my used oil container.

Thanks for all the input. I just got the new hose from IDparts and installed it along with the Provent now all set for many more miles. I just put a drain hose on the provent and will drain it every time I change the oil.
