Ok, so i was trying to figure out if I have a vac leak (I can hear hissing sound) and saw this but have no idea where it is supposed to be plugged into (if anywhere? ) It comes out of the block between cyl 1 and 3 as shown in the pics:
Ok I found its spot! Its on some black thing that sits below the solenoid, does that come with it if u buy a new one? The plastic piece the hose goes over actually broke off inside the hose
A "new one" what? hose? No, Mazda will sell you a new prebent hose, but it wil cost 10x the same as a unbent vac hose from any auto parts store. If you mean "new one", the plastic piece, then yes, it will have a new nipple for you to attach your vacuum hose to.
You can try super gluing the nipple back onto the plastic piece (not sure which vac silinoid you broke, but it is deffinately a vac silinoid). You can try JB Weld too, but either way make sure you do not clog the hole. Also, make sure the plastic pieces are clean and if they broke smoothly you'll need to rough up the contact faces with some sand paper or something to help them stay together.

The black plastic thing is the item labeled "vacuum chamber" in this picture. It's sort of important. You'll need to get one off a junk yard car. I doubt you can even buy it from Mazda anymore.

I think I have a set of those vac chambers laying around if you broke a nipple off.
they are critical to the VRIS system, and something else T's off of it.... I forget. Either FPR or EGR.

Omg...I for sure found my vac leak problem.. but have NO IDEA how to fix this and what it is even called/does? Please someone see if they know anything about it and if they know a place I can buy one.
It has a hose that attachs to a metal spout on the intake mani right next to cyl 1 that is this thing:
and this is the hose/circle thing I took out:
My brother owned this car before me and said when he redid the intake manifold it broke but he super glued it back together. I also found the other side of the yellow circle thing sitting next to the cyl 3 spark plug wire,
It is the one way valve for the vac chambers for the VRIS.
They are hard to come by . They need to be a good check valve if you're going aftermarket. You get what you pay for. There is a way in the manuals to test it. But it needs to hold full vacuum.

It still affects the VRIS? It doesn't go to the VRIS at all, it drops off that spout and goes below the intake mani (on the outside) and over to where the cyl 3 is into something else. Would the link I put up be a good replacement? I'm outta options =/
That chec valve fills those black chambers under the intake manifold. Those chamber provide vacuum to the VRIS solenoids when you're at WOT (zero manifold vacuum)
When you shift, it evacuates the chambers again, and then next run up the RPM range at WOT, you have vac for the VRIS again.
If it doesn't hold vacuum, you won't get VRIS past just a few flips of them if any at all.

Looks good to me. Its description pretty much exactly matches what its supposed to do.

Ok. Looks like I'm gonna take off the intake manifold tomorrow and try to just jb weld that part together to the best of my ability (it broke the plastic spout that comes out of what im guessing is the vac chamber in the intake?)
