I installed my Mishimoto catch can today. Installation was no problem. While I was installing it, my ball valve showed up. Apparently there is a link to the wrong part elsewhere on this forum because I ordered based on that other link and the valve won't clear the bottom of the catch can so you cannot open it.
Oh, well. No big deal. I just ordered the correct one that is linked in post #7 above (Thank you
@securityguy).
BTW, I'm getting zero noise/hiss from the Mishimoto. The quality of the included hoses seems very good, but they have no markings on them which I suspect means they aren't great. But they seem more than robust enough for this particular application. If my OCD gets me, I may upgrade to transmission oil cooler lines like others have suggested.
