37 I.e. is it defective or not, not really any way to tell. But I can post a pic of the part to itself its off the car. There is no way you can fuck up installing this, its literally place oring and tighten three bolts. The o ring is properly placed. Now they claim that's all you have to do, but that did not prove true. Since the o ring didn't seem crushed at all I can only assume that the the etching for the oring is too deep.
I only post this for information, if any else has success with this part that would be great to know otherwise it didn't work at all for me. Stock is back on with rtv I've got work in the morning...
