Just picked up a Greddy Type S second hand. Now, this thing has two vaccum ports on it. One is on the black "hat" cover and the other is in the aluminum casting part right under the first. Which one do I plug into the intake manifold boss and do I leave one unplugged or not? Pics to be posted later if we need them. Thanks

Well, I'm lost. I must be testing it wrong because I even took the unit apart and took the smaller spring out (there are two, the smaller is inside the larger) and it still does not respond. The Type S is designed just like the stock BOV. It has a spring in the upper cap portion that is on top of a plate connected to a shaft which controls the valve at the bottom. Down around the bottom of the plate that the spring sits on it is surrounded by a rubber gasket that seals the bottom portion from the top. Now, the upper boss on the unit feeds the upper portion of the cap and the lower angled boss feeds air underneath the rubber gasket just like the small hole on the gasket surface of the stock unit. Any ideas?
