From what I read, there is supposed to be no > suction when warm, correct? No, they never seal off completely. OTOH, they don't leak enough to make any difference. The correct way to test them is to see if the idle speed changes any when you shut off the air with your thumb when the engine's warm. If the idle speed does not change, the AAR has closed enough. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
