So recently I tried to get my 4run to pass smog and everything was peachy keen except there's a hose about 5/8" thick on the front side of my valve cover that goes nowhere. it didn't pass the visual inspection. in order to get it to pass I need figure out where that hose gets connected to. Every vaccum hose diagram I've seen has that hose cut off. Can anyone help me out?

 

Does this help?

 

it's actually not on that one either... it's one that's right behind the oil filler cap. thanks for the help though buddy

 

should go to the throttle body
edit- or the intake plenum

 

I don't think there's any intake ports big enough for that hose on either the intake plenum or the TB. It's almost as thick as a garden water hose

 

take a picture. I'm also gonna say it goes to the intake.

 

Check this link for pics. The answer is there.

I did find the answer....thank you very much!!! Now all I have to do is find a stock hose and get rid of this garden hose that's on my valve cover.
good looking out homie.
btw: this is the first isht brown 4run I've ever seen. it's pimp as ufck
thanks again

 

I forgot the turbo's were different.... /me smacks self.
I learned something today!!!!

 

It's cool, I still appreciate your help. clean 4 run. where did you find those tube bumpers? I've been looking for them for quite some time

 

They were on it when I bought it a couple years ago. They're smittybilt if I remember correctly. The front bumper's kind of racked, think the PO bumped something on the left side, but it doesn't bug me.
