active bov not right

[maxlax7910]

I just thought I just finished installing stage two on my 96 m3 c38. but I took it for a spin and the bov sounds like it has a piece of paper slowly flopping around as it blows off. Any one have any ideas. could it be from the vac line or the gasket?

Any help or ideas are much appriciated.

Either the BPV return hose is kinked, or the vacuum line is obstructed/pinched.

I fixed it, the vac line had a slit in it. it was kinda easy to find once I looked.
