[quote=dirtydog;2294591]Constant filter replacement would be necessary as it would fill up with oil and if not replaced, would leak oil down the side of your engine. Can be pretty messy on certain engine's.
Won't work. The oil is pulled to the T/B by vacuum. You can make as many loops as you want and wrap 100ft of hose around the entire truck. The oil will still make it's way to the T/B. it's all vacuum that pulls it there.

I did the same thing on my bike. If you disconnect it from the air intake it can not make a vacuum. No where to create a vacuum.
I've actually added a loop and all -- keeps oil from going into the air intake. Botta bing botta boom. Gravity works a lot more effectively on oil than on air, too -- that's the basic concept that is used in every toilet to keep good fresh air on one side and bad stinky air on the other.

I think you guys are missing the whole point here or just don't understand how a PVC system operates. It's meant to circulate fresh air into the crankcase via breather on one side and re-circulate the bad vapors to the T/B to be burned off which is located on the otherside.
Once you disconnect the hose and drop it to the ground, you will eliminate that vacuum which is cause from the T/B sucking air in. That is old school and it has been eliminated on gassers because of oil on the road which is caused from just that.
There are downsides on even doing that with forgetting about the oil on the road completely. The pcv valve loses practically all it's function when you do that. it's routed to the t/b so it can detect the difference in pressure between the intake manifold and the crankcase.
If you use an oil catch can and still route the line to it's proper location, you still retain the function the the pcv valve and eliminate the oil issue.
If you use a breather or drop the line to the ground, you have essentially eliminated the pcv's use.
