What is this hose?

Anyone know what this hose is on the top of the 5VZ? It runs from the intake to a fitting on the driver side valve cover

 

I thought that was for the egr valve once upon a time. Not it's just a vent.

 

I was told it was the EGR too but pretty sure its not. You think its the fresh air side of the PCV system?

 

Its def something along these lines. I had the same thing but it connected at a different location.

 

Im putting on a new intake and wont be able to connect it. I think I can get away with a breather on the fitting but not sure. The PCV is running to a vented catch can...

 

Another intake????

Try capping it off and see if it make a difference.

Found this today......

BTW it looks like we'll be working on Paul's wiring next Friday after lunchtime.

 

I dont know if I want to cap it. I think its the fresh air supply for the crank case. Old oily air out the PCV and fresh air in through this fitting...

Yeah man, great price on that S/C kit! You or Paul need to snatch that up quick.

On the 4th? Probably can't do, gonna be with family...

 

Gots no monies for the S/C.

 

what intake are you going with that it will not connect?

 

Turbo

Wouldn't want it connected anyways, it would pressurize the crank.
