Clearwater area, mind you I've been running a JVC CC for 2-3 months now with price and easy of install being why I chose it since it has factory quick disconnects, but that tour does sound tantalizing.

It passes first the air filter, then the MAF sensor (as this incoming air ultimately becomes part of the air/fuel mixture in the combustion chamber), then incorporated into the MAF is the IAT (Intake Air Temp sensor), and then the MAP sensor. So before any of it reaches the combustion chamber it is measured by each of those sensors so the ECU can determine the amount of fuel, ignition timing, and more that is needed to achieve the correct targeted A/F ratio. From there the spent exhaust gasses pass the upstream O2 senors (sensors 1) and this data lets the ECU know what needs to be done to meet the pre-set parameters in the tune. If it's lean, more fuel is added. If rich, some is taken away.


So, when you mistakenly assume pressure is always going to be present, and think "I'll just put a breather here to release pressure and all will be fine".

Correct, lack of knowledge/borderline ignorance made me believe venting the clean side might have no side effect as I thought it also produced blow-by, albeit in way less quantity than the dirty side, and since figuring out it's the contrary, I thought adding a vent/filter on the clean side would have no ill effects either since the engine has more air available, but no, I discovered this needs to have a vacuum, which is the next thing I'll have to look up since it's related to this.

So it will pull in air that has NOT passed the MAF/IAT/MAP sensors so it confuses the ECU because none of the data coming in matches the tables as expected in the tune, so to protect the engine it adds more fuel. Then the upstream O2's tell the ECU it is too rich, so it takes fuel away. It will show in a scan short term trims adding and subtracting fuel so things are far from ideal. So we NEVER vent or use breathers (at least the few that understand this). Those that do vent are using technology from the pre 1960's and that leaves most of the wear and damage causing substances in the crankcase to mix with the oil and attack the metal internal parts and more.

Re watch that video a few times to understand better, and ask questions on any part not totally clear. Education is key as you should never blindly make a decision based on an add or because someone else told you to. Understand each function the PCV system provides (only one is pollution related) and how each affected part of the engine relies on one or more. I mentioned the piston rings and retaining stability. In engines of old (prior to the 1990's mainly) all had a high tension piston ring so this was not an issue, but as more demands of better fuel economy popped up, several changes were made. One is the piston rings were now similar to what we had been doing with race engines for decades. We used lighter low tension piston rings and today that's standard. That frees up HP and increases fuel economy, as well as running far too thin of oils to properly protect. So, all piston rings are now low tension, but several factors are critical to maintain stability, and the one we can control is the need for pressure above the rings and suction below. We are one of the only systems that provides this.

Lots more to learn that were happy to share.

Thanks! This is the kind of information that is really hard to come by in videos/articles; for what I can tell, 2019+ requirements changed to 0W-40 instead of 5W-30 so my car already has the thicker oil, next oil change I'll make sure to get the ESP formula.
