Weird bov sound. Boost leak? Video inside

Bmw3thirty5 · 05-09-2014, 11:14 PM

I randomly started getting a different sound from my bov. It's ER CP with synapse bov. On map 2 (14.5) psi I was only getting about 13. Is this a leak? I haven't check connection to inter cooler yet but I checked charge pipe and it's good. I attached the video and you can hear the bov isn't as loud as it should be and it blows off like 3 little blows consecutively. Any ideas would be appreciated thank you.

Hey man, i have the identical set up. I was having this problem for awhile and finally resolved it. And yes, it was a small leak. Check your vac hoses in the back, also check where the vac hoses attach to the back of BOV. I actually took my nipples out and wrapped them in that white pressure tape because one was leaking. Also make sure you are not leaking where you attached to the factory intercooler piping.

So what exactly solved your problem?

I'm guessing the faulty vacuum line was causing his leak.
