Catch cans are very difficult to get data points on. The important things you want to know is, is the can getting oil? That's easy to check, I'll open the drain valve in a few days and see. Next, is the oil staying in the catch can? So I'll disconnect the large vacuum source line and check to see if it's dry, and disconnect it from the inlet tube, make sure that connection is dry. Are you smelling oil? There shouldn't be any oil smells under any driving conditions.
The last thing, and this is the best test but also the most difficult, is getting a pressure/vacuum reading from the valve cover and/or crankcase. So not only is this difficult to get, but it isn't important at idle and free-rev, you really want to see it under throttle, under load. So you'd need to datalog. Maybe someday when I drill my valve cover to add more ports, but not going to do that right now.
The ADE fittings disappointed me. The fittings are different sizes, the PCV valve one being an 8, and other a 10. There's no reason not to make them both 10s, which would be a lot easier and slightly more effective. I stepped mine up to 10 immediately after the fitting. The smaller fitting from ADE, the 8 one, is also machined wildly incorrectly. The flange angle is supposed to be 37 degrees, and it isn't, it is far steeper, more like 65. I'm wondering if it isn't 53 degrees, and the manufacturer cut it opposite. Either way it's wrong. Not a huge deal since it shouldn't be under pressure, but it is more prone to leaking the way it is. I'll report back if I find leaks.
If you want one, you're going to have to pay for it! I'd need $500 per can, and that does not include the ADE fittings. But I could customize it in almost any way you'd like, and it'd be powder coated however you'd like.
