Engine Valve ???
 
What is this tube ( traced in green and identified by the red arrows ) and where do I get another one? It makes this weird noise like air isn't passing through properly and when I clamp the tube the sound goes away. Thanks in advance.

That's the PCV valve hose.

What ever you do DO NOT TOUCH the bronze/golden colored one near the Throttle Body. That's your EGR and it will burn the sh!t out of your hand.

yup like i said before, its the PCV hose, under the black tank looking thing is the PCV valve which is what you will probably need to replace. not the hose. i think they are about $25.

the EGR is the copper colored tube at the front of the manifold. Listen to Escape and dont touch it.....LOL. Also...dont do like me and pull it out, lose the seal and then bend the tube....LOL. Itll cost ya about $100 if ya do....:thumbsup:

ok guys I am confused so I ned a litttle help.

Got it, EGR is the copper tube pass side of the TB. Very hot, I have touched it, and I would recommend not touching it. HAHA

PCV hose, marked in green, goes to the black circular housing that has the PCV valve in it.

SOOO WTF is the tube that connects to the nipple on the intake and runs across the engine to below the oil cap (pic below)????? I replaced it with a filter b/c I was sick of the tube...what exactly did I do other that IMO clean up the engine bay a little?? Thanks for the help guys, I feel like a total newb

It's a recirculating tube for lack of better description. The oil that doesn't get burned off in the manifold is supposed to return back into the intake/TB and back into the manifold via that tube for a second attempt at burning it off within the engine, not the atmosphere.

You added a filter so vapors and what-not are exiting through the filter and not back into the manifold.. illegal in CA.. just put the tube back on if you go for a smog check.
