Next question, (this will never end) after some research on BOV's, it looks like we should be closed at idle. My valve will not a-just to closed, Turbosmart sells higher rate springs.
The only thing this should change is the hiss at idle and a small chance of intake charge contamination.
In the GTM 1.0 you recycle the BOV air but in the 1.5 and 2.0 it is open. If you through a belt you would sucking in unfiltered air. I am going to put a small K&N on my valve and get the correct spring to close at idle.
