I just got finished replacing my intercooler piping, hoping that it was the last of my boost problems (it had a 4 inch long split). Was using my Fighters-Garage boost leak tester, located another boost leak on the driver's side of the block. I'm looking up and down my vacuum diagrams and can't figure out what the hell it is.




It's just a nipple that's directly above the MAZDA 13B writing on the rear rotor housing. It's leaking boost and oil and there's no empty vacuum lines around it so I need to know if anyone knows where this nipple is supposed to feed to.

Thanks.

 

Please help, it's the empty nipple in both of the pics. The hose that goes to it will be a 6mm or 1/4 hose. I want to finish this up before it gets too dark.

 

that is the catch tank from the purge control solenoid valve.
F10 in the fsm manual.

so from the intake to the purge control valve to the catch tank to the top of the chacoal canister.

 

It gos nowhere, Just cap it.

bryant - I went over and over my vacuum diagram and everything regarding the purge control/charcoal canister and catch tank is hooked up and fine.

As you can kinda see in pic #2, the nipple comes off the top of the lower half of the oil filler neck assembly that runs along side the intermediate housing. Gadd are you sure that this is meant to be capped? I'm guessing that would make sense, because there's no remains of a vacuum line that once was there. What's a common place that I could buy a 1/4 inch cap like that?

Thanks guys.
