greetings...

replaced my pcv today... it really needed it. the hose between it and the air filter assembly was completely clogged. spent about an hour cleaning everything out (including the weird channel inside the air filter assembly... which was also clogged). amazing how much better the car idles now.

anyway, when diconnecting the air filter assembly i came across the part in picture one (attached). i'm wondering what it is.

furthermore... inside the hose between it (whatever it is) and the air filter assembly was the screw pictured in image 2.

can anyone explain why it may have been there? i removed it during my afore mentioned service and things seem to be running great. seems a bit screwy (pardon the pun) that someone would have put a screw inside the hose.
