Ok so i had a vacuum leak and i found a hose that was cracked the problem is i cant find a part number to replace it. My car is completely stock so it is a stock hose.
It is the elbow that comes off the back of the C.V.R. Its not labeled on the vacuum hose diagram. Can anyone ID this or give me a part number? Been googling for a while with no luck.

 

This one?

 

From the pic you posted, it appears you have the bov still mounted (looks just like what you are holding in your hand on the "y" pipe.except you are holding correct me if I'm wrong the cav which is located on the y pipe just at the rear before it connects to the second turbo facing up....that peace mounts to the y pipe the other end to the intake

 

Oops , maybe I should have read the post before giving my answer.good luck

 

Check out mazdatrix from pre-control hose #13-7650-n3a1

 

yes thats it

 

Yeah thats your pre-control hose. Mazdatrix and Atkinsrotary has it.

You might want to call Ray Crowe at Malloy Mazda as well. He usually has the best prices and flat rate shipping, so if you have other things you need, grab them all in one order.

 

will do thanks for all the help and quick replies guys

 

try N3A1-13-765

 

If you're ever in a bind you can always hit up your local autoparts shop and ask to browse their hose selections. Just because they don't have the right one doesn't mean you can't grab a longer hose and cut out the section you need. It's a great quick fix and can also be a permanent solution for much cheaper.

 

^yea i agree, you don't need the stock hose.
Any hose with the correct inner diameter; that can be bent a bit without the sidewalls collapsing should work fine

 

Yeah, thats the CRV (Charge Relief Valve). It is not a BOV as was incorrectly stated somewhere above.

Just find a universal parts-store hose with the correct internal diameter, which has a 90 degree bend comparable to that, and trim to suit. I do this for many hoses that I cant be bothered waiting for in the mail.

With that hose split, (assuming the rest of the system works fine) the secondary turbocharger will not come online, or will show reduced boost after approx 4000rpm to redline. It will still be driveable but down on power up top.

Once you replace it, verify that you are getting the correct 10-8-10-8 boost pattern through the rev range. If not, you also have some problems elsewhere.

(Another common cause of low secondary boost is the green check valve located under the pressure tank, splitting in half. Easy & quick to check and confirm it is still working by removing the pressure tank and having a look.)
