mine spits oil under boost... however that may just be a result of pressurizing the crankcase via the manifold and forcing it out there. i may grab a 3 port and only use 2 for now...either way i need to get a check valve on the other

alright i'll throw something on the driver side to manifold with a check valve in it.
i grabbed somewhat of a bulk head fitting to put the passenger side back into the intake elbow. I was going to "filter" it in case positive pressure was forced out there still i dont want to shove it back in front of turbo.

So I changed out my drain valve with the better, easier shut off valve. I didn't know that the catch can.com catch an was empty inside. I thought there would have been a filter of some sort. e3e92b50f4f3303a120df7ee6dea8163.jpgd9a4c5f308fb0ab5ae121101bfc87926.jpg7cf858af6ed04bc61f9e84744311d1a1.jpgfd39a5d69b6d85848512e1715b1b070a.jpg

I presume it's at the top then? I only took off the bottom to change the drain plug and it looked empty inside.

Yeah. All the filtering/coalescing stuff (the "catch" part) is up top and the part you removed is the reservoir (the "can" part). There's a tube in the center with a cap on the end with about 8 holes in it. That cap unscrews, and there's filter media behind that. The oily mist goes into the top center of the assembly and passes downward through this filter media. The tiny oil droplets condense and collect to each other in the filter to fall out of suspension from the air, then they drip down into the can. The filtered air is sucked out through the outlet port in the side of the reservoir. I wrapped my scrubber pad around that center tube and stuffed it back into the can. It's a tight fit, but this holds the pad in place. You just have to make sure it's tucked it and not getting caught up in the threads as you screw the top back to the bottom. It sounds more difficult than it actually is. The scrubber pad basically acts as a second filter so the air is getting scrubbed twice. I'd say that it definitely improved the efficiency cuz I've consistently drained about 1 ounce more than the 2 ounces I consistently drained before.

Just installed my catch can yesterday. Drove around 50-60 miles today, and opened it to see if it would show any signs of working. See attached.

That's a lot for only 50-60 miles. You should check into the other oil consumption measures, primarily the updated rocker cover. Also clean your intake manifold and do the GM upper engine cleaning procedure since you've obviously had a lot of oil going through it.
