I searched, but didn't see if anybody had ever tried this, but I wanted to know if this makes sense. I am getting rid of the PCV and putting a catch can in place (1 line goes to catch can and two left over lines that go to the TB). I also wanted to get rid of the check valve going to the intake to make my TID simplier. So I thought about venting the line below the oil filler neck and PCV line to an oil catch can and then hooking the outlet from the charcaol canister to one of the left over lines from removing the PCV that goes to the TB. (Side note: I am in a emissions state, but they aren't to strict on visuals here) This way I can still run gas fumes to the intake system, but elimante dirty fumes and oil condensation from the oil system from going to the intake system. I am not quite sure which line to connect the Charcoal Canister line to since there are two lines left over on the PCV? I think the line that connects on the bottom of the valve is the outlet line (there are two line that connect to the bottom of the PCV, one that goes to the block and one that goes to the TB)? Does this seem feasiable? Maek sense to anyone?

Has anyone ever thought of this or heard of anyone try it?

opinions? I'm I crazy?

relax on the post whoring someone is always reading, even when you don't think they are.
This idea is fine, if not, a good one. To make it emission friendly, you could route the catch can filter (remove filter and use a vac line) back into the intake as well. The stock PCV system will route oil back into the intake becuase there is no catch can, there is only the charcoal canister, and there is a one way valve that routes actuall oil into the intake. Honestly I think that leaving the pcv line that goes to the canistor will not allow oil to enter the intake. Routing a rubber hose back into the intake from the catch can will keep the fumes in the intake, but the oil out, just remember to change the catch can so it doesn't overflow over time.
This is all 'environmentally' speaking of course, just so that its emissions friendly. As most of us would even give a ****, im just telling you a way to keep the bad fumes other than exhaust, within the engine.
Keeping the oil out of the intake is awesome, it prevents the intake from clogging up with gunk from the oil and dirt deposites that bypass the filter over time. This is why all stock intakes for the seven and many other cars are just coated in black gunk, becuase of the stock PCV routing system.

Route the charcoal canister to the purge valve. That's what I will be doing.

You can go one step further and replace the purge valve with a generic PCV valve, and then route the canister to a 2nd PCV valve.

would that be better to route the charcoal canister line to the PCV value where the line from the oil filler neck was instead of taking the charcoal canister line a directly hooking it to one of the lines going to the TB (maybe it would be good to put a check valve it between?)? I was looking at the FSM and trying to figure exactly how the stock system operates and it seems as though under normal driving conditions (while the intake is in vaccum) it uses that vaccum from the intake system to suck gases from the oil filler neck into the intake system? So in theory placing an oil catch can on would not give the same suction effect that system is use to.

When the engine is under vacuum, the purge valve opens and sucks vapour from the "crankcase". This is standard operation in almost every combustion engine. A similar thing happens with the charcoal canister. Similar enough that you can just route the vent from the canister into your purge valve.

Oil catch-cans are a bandaid for those who do not wish to keep the system operating as the factory designed it. I have never understood this approach, because it means that you now must mount a big can somewhere, and check it's level every once and a while. The stock systems uses 3 vacuum hoses (you can reduce this to 2 by using a generic PCV valve) and maintains itself automatically.
