Anyone know if the release pressure can be varied on the APS BOV? There's that grub screw sticking out the end which - I think - is for adjusting the release pressure, but I'm not convinced Might do something like screw up the idle...

 

I think the screw adjusts how much it will allow teh piston to travel and thus release VTA as opposed to re-circ from what I remember when I took mine appart a few months back.

I dont think that it will actually change teh level that it releases at.

 

Oh poo.
Although I'd have thought that this would still make a difference? But you've taken the thing apart - I've just glared at it from the outside!
Thanks, though

 

It only appears to be a stop I am afraid.

curiosity got the better of me though I just had to take it appart
