What in the hell is this shit suppose to do!?!?!?

I have no idea, but I've seen a setup like that somewhere before (probably a magazine or something). Curious though, I wonder how long it will take before the heat from the headers melts the rubber hoses.

a lot of NA motor setups that make a lot of power and rev high contain a ton of crank case pressure. Normally if you have too much crankcase pressure you will start to blow the O rings on the valve cover gasket out, etc... which is not to good. To solve this people tap another hole in the valve cover (sometimes up to 2 holes added to the valve cover) to help release the pressure. Also people tap the block (oil galleys) to help reduce oil pressure on tight clearence motors.
This setup is normal and does work really well for that type of application. With my car with 280+whp JRSC I did not have a problem with crank case pressure, however I did tap the block to help drop oil pressure. And yes those hose will probally wear quickly from heat, so a black or clear braided line would be preferred.

It's kind of like an open pcv setup which vents crankcase pressure. It should work because the crankcase pressure can escape to the valve cover via the oil galleys. Not sure if this guy has done anything to the actual pcv valve though...
However, I do agree those clear lines are not going to last due to the heat from the header.

That is a CR VTEC engine. I guess they are trying to get more air into the the crank case because the breather tube must not be getting enough air in by itself. The problem with this may be that there is no out for the crankcase; this setup really needs the catch can at the other end where the crankcase gasses are vented out, not where the fresh air is brought in.
