PCV hose question
 

I discovered that my PCV valve is puking oil into the intake. My Camaro does the same thing so I put a air compressor inline filter in the pcv line. Worked great so I plan to do the same thing here. Problem is there are 3 lines going to this PCV valve. Two lines go to the throttle body and one looks like it goes to the lower intake manifold. I have no idea what these other two lines are for. Looks like the actual PCV line is made of plastic and the others are rubber. Can you guys explain how this system works. This motor is completely different from what Im used to. Thanks

Figured it out. Coolant lines.
