Under engine when stopped at lights. I ran ~21" hose down front of engine and out one of the lower close out panel. I could see the plume from driver's seat when stopped.
I am in the camp of trying to stop both the soot and oil from getting to intake. If oil gets all the way to intake port, heat of the engine will cook it down to coke. I know, we can't stop other oil sources but doing best I can. Yesterday, I removed about 1oz of oil from catch can after 1390 miles driven. I have same brand can as you. My run to can is more like 10" each direction though. Can is just in front of engine's thermostat so it should be getting cool air.

I recall others emptying ~5 oz for perhaps a 5000 mile drive period. Mark M, can you provide your numbers please? Different people are seeing different rates of collection. I wonder aloud if predominant use is freeway speed versus local driving(me) influences this ?
