are you just boosting mildly?

it may not blow off until you try pushing the turbo and RPMs higher in the upper ranges.

some blow off valves are not very sensitive to rotary vacuum levels so they tend to only blow off under hard driving situations. maybe someone who has one of these BOVs can confirm or deny this.

click on "Post a Reply" then scroll down to "manage attachments"

if the pics are too large you either need to modify them to size or host them offsite.

Hmmm...everything looks kosher.

You see the ~1/2" thick diameter hose right under the BAC valve right behind the BOV?
CLAMP BOTH ENDS!
This stupid hose tends to leak and blow off under higher boost (remember stock is 6 - 8psi).
I dunno why Mazda didn't put clamps on the damn thing. :P
