Whether or not it's right for your car, I can't say as I don't know anything about Audis. However, it's normal for there to be some (not a lot) oil in the intake of the cars I'm familiar with.
First: what you're suggesting is illegal if you live in a state where it's illegal to remove an emissions device. At a minimum, you're making your car non-street legal. That aside, you're creating pollution for no good reason. There's a zero percent chance that your catch can will be more effective than a modern catalytic converter, especially when ...
The pulsing should not be a huge issue. Remember that your 4-cyl engine will not have a constant vacuum associated with it as it is only drawing it twice per revolution of the crankshaft, which means you'll get vacuum pulses. Vehicles with more cylinders will have a more constant vacuum draw, but will still have vacuum pulses ... they'll just be less ...
The PCV system reduces pollution by collecting "blow-by" (unburned gasoline and oil vapor) that would otherwise be vented into the air we breathe. The PCV system routes blow-by back to the intake system so it can be burned properly. PCV is designed to handle these by-products correctly; it is not harmful to the engine. Placing a closed container on the end ...
I think you need to give more information about the application to attract answers. For example, define "dissipate": do you mean to scrub off enough thermal energy to bring temps to within 2 degrees of ambient? 20? 200? Is the goal to use this intermittently or for constant use? Big difference in BTU's there. And is your goal to bring the shaft to 0 rpm ...
If the oil return passages are plugged, then at high rpm or after sustained operation you may be building up lots of oil in the head which is then finding it's way out into the airbox. Since you did have some parts come apart inside the top end, maybe some of the baffle ended up in the return passages and is preventing sufficient oil drainback.
For such a cheap part, if you suspect the vacuum hoses then just replace it to remove it from the list of possible causes. From my knowledge the MJ tritons were still carburettor. If this is the case then perhaps it might be worth trying to diagnose a possible carburettor issue. If it performs this behaviour at any particular throttle position then it might ...
Take Timo's advice. If it 'aint broke, don't fix it. If it's not a scheduled service item, don't mess with it unless you've actually got a problem.
