Okay, so I did about 30 miles of mixed driving with a couple of WOT pulls. No issues as far as performance and no residue from oil in the engine bay. The top of the valve, under the filter is dry. This is with all PCV hoses connected. Now, I would think that you may see more oil misting if you plug the driver's side PCV hose because the crank case ventilation has to go somewhere, in which then...most of it would go through the oil cap filter. I did notice at idle that there is a slight amount of airflow coming out of the cap filter...it is not pulling air in at idle. Which is what it's supposed to do with the valve and all. Other than that, the engine is a little louder ( valve train noise coming out of the filter) and there is a faint smell of oil in the engine bay. I'm still on the fence on whether I will keep this on or put the oil cap back on. I did want to test this, though I'm not really sure what I expected from it....nothing really. At least it's being tested for the community.
After the drive...
