Hose on the back of the intake?

[BlownAway]

I have a 95 GSX and does this hose have to be connected or can it also be blocked.

I'm assuming this is the intake to the turbo not the intake manifold. That hose should be connected to your PVC vent to suck blow by gases back into the intake. At the very least plug the hose/nipple to prevent debris/unmetered air from entering your engine.

Wrong. The PCV valve is connected to the intake manifold by a hose. It does not go to the intake pipe. There are 4 hoses connected to the intake pipe: boost control solenoid, valve cover breather, charcoal canister, and bov tube. You don't need the bcs hose if you have a mbc - block the port off on the intake pipe. If you don't have a mbc you need the bcs hose. You need the other 3 hoses.

Yeah i knew the term PVC vent seemed wrong to me I mean the valve cover breather. I should of clarified when the PVC is closed during boost the blow by gases are forced out the valve cover breather and the hose connects to the intake to turbo to suck them back into the system.

The only things that should be on the intake to the turbo should be the valve cover breather hose and the reciruclation pipe. The charcoal canister should be part of the EGR system. The BOV should be coming from the intake manifold. The stock boost solenoid hose is connected to the wastegate.

Thanks alot I will be taking care of that today.

Wrong.


As turbosax 2 stated:

There are 4 hoses connected to the intake pipe: boost control solenoid, valve cover breather, charcoal canister, and bov tube. You don't need the bcs hose if you have a mbc - block the port off on the intake pipe. If you don't have a mbc you need the bcs hose. You need the other 3 hoses.

1. The charcoal canister should be connected to the intake pipe, even though it's part of the EGR system (unless you deleted your emissions, then it doesn't need to be).

2. The valve cover breather (on the passengers side of the car) should be connected to the intake manifold, preferably with a catch can inline.

3. The bov recirculation tube should be connected, unless you're running a speed density or blow thru setup.

4. The one hose from the BSC (or wastegate control solenoid) should be connected, unless you have an MBC.

If you would like a diagram, I will draw one up (or post a pic of my stock intake with the holes labeled.

No, he is right. This is #2 in my above post (the valve cover breather). Just don't follow greeneclipse's statement about leaving it hanging or putting a breather filter on it. It needs to be hooked up and if you put a breather filter on it, you'll have oil all over your engine bay since there's a bit of oil that goes through that line. Which is why it's recommended to put a catch can on there.

The inlet on the intake pipe is on the back of it (towards firewall) next to the charcoal line inlet.
