BOV gone silent. Boost leak?

[bodilx6]

All of a sudden (no hard driving) my BOV is going very quiet and seems to need quite a lot more stick to give any sound. Boost might be building slower/leaking but I'm not entirely sure (havent been able to really push it yet)

Boost is building but when it should be released by the BOV it just gets a very sorry psssshh compared to normal.

 

I've tried something like this before and then it was just a ruptured vacuum line going to the BOV. This was very apparend due to the sound of "escaping vacuum" but this is not to be heard now and I can't see any pipe/hose popped off or anything.

 

Its not like an IC pipe has popped off, cause boost is building as mentioned and happely towards the 1 bar.

 

But just creaping of from a stop and lifting used to build a bit of boost and a PFFFT but doesnt now.

 

What can this be?

Just checked everything connected to the BOV. Hose to the pressure side of the intake is fine, the vacuum line to the inlet manifol look good and the BOV is closed nicely.

 

Could this be an issue with the wastegate not closing properly? Or anywhere else than the BOV itself and its connections?

Just figured that it isnt a boost leak, since boost is building nicely upto 1.2 bar as before. The BOV is for some reason not letting boost out as it is supposted to. My vacuum seems fine according to my boost meter and the vacuum line to the BOV is fine also. I have disassembled the BOV and all seems well there to. Really really weird.

 

Any thoughts? Anyone?
