And now my idle is higher than normal. I reset the ECU and drove around for a while, but it didn't change much. I will check the TPS tomorrow, but that wasn't the reason for my post.

When I was cleaning the valve, which was not as dirty as my throttle body was, I was thinking that I will probably have to do this in another 80k miles or so... Is there a way to fully remove the oil from the blow-by gasses?

I mean, there is. There are oil catch cans on the market that will also return the oil to the sump, but that would be overkill for a b230f because the actual amount of oil vaporized is relatively small (if your breather system is clean and not plugged). But perhaps an oil catch without a return line and the required plumbing might be worth it. Something simple to drain every third oil change or so. I have seen some cheap renditions that look like an air/oil separator from an air compressor, but they seem sketchy. There are also decently priced ones from MFactory that have 15mm fitting and an indicator to show the oil level. I understand that this might be overkill, but it sure would be nice to not have to clean the throttle body or IAC valve again.

Question is: Would this create any kind of resistance or hinder the PCV system in anyway?
