TIAL BOV issue.

I thought I noticed the swissshhh sound overtime wasn't as loud and then one day after a downshift I don't really hear it, just slightly. Pulled vacuum and it was perfect, visually it's working. Something gone bad inside?

Don't those have preload springs inside? You could have a bad spring. When you are sitting there idle, is it allowing boost out?

No, it's working perfect. I was told by a vendor to remove it and check for debris that might have in.
