Now let me clarify this is not attacking you as only you and the other party your talking to know the truth. And, this is such an inexpensive mod to do correctly, why would anyone want to take the chance and not protect their investment the best way possible?
I would argue with all the years of doing oil analysis that your mistaken on this, and there is white paper after white paper on this from engineers and engine builders doing the oil analysis's as well (I would go out on a limb and suspect someone is feeding you this inaccurate info and you are just repeating what they are telling you so not attacking you, your source is BS'ing).
I have been building race and performance engines for over 38 years, doing super charging and turbo charging of all types since the mid 1970's, and have owned, raced, managed, sponsored professional drag teams for ages in both NHRA & IHRA in multiple classes, with years of Divisional, National, and World Championships through this time as well and oil analysis, proper crankcase evacuation, and durability keep us in the winners circle so I am not just pushing a product or arguing for arguments sake, this is actual experaince....and most likely, whoever is feeding you this inaccurate info was not even born yet when we were racing and building engines...and is a competitor not playing fair.
Read (long) from the aircraft engeering side (where the pilot/passengers life is dependant upon proper crankcase evac to keep engine sound:

Another engineers standpoint: (many of these deal with off road use)

But where do these damaging compounds come from?
A clogged or defective PCV valve can contribute to sludge formation. If this valve does not operate properly, harmful exhaust gases remain in the crankcase.
These gases, which contain water, acids, soot, etc., promote sludge. Excessive amount of fuel due to leaky fuel injectors, malfunctioning choke mechanism or failed oxygen sensor can also contribute to sludge formation.
Maintain your vehicle in good operating condition. Check fluid levels, filters, belts and hoses periodically.
Make sure your car is well tuned.
Most light duty vehicles sold in USA after 1996 when OBD-II regulations went into effect, no longer require any "normal" tune-ups.
However when you check engine (MIL) light comes on and stays on, have your vehicle checked by a professional mechanic with proper computer diagnostic tool.
(That is the computer gizmo that connects to the OBD-II port in your vehicle).
The
MIL (Malfunction Indicator Light) also known as "
Engine Check Light" does not necessarily indicate any engine problems, it is designed only to indicate any failure that results in excessive tailpipe and/or evaporative emissions from your vehicle, however and efficient combustion produces far fewer harmful acids, soot, unburned fuel than a poorly or rough running engine.
I can go on and on, but the point is, yes, plenty run with inadequate carnkcase evacuation and "see" no obvious over night damage" so the assumption is generally
"all is fine".
I am sharing a lifetime of experiance and first hand knowledge. I invite you if ever in the area to stop in a tour the facility and see all this forst hand up close and personal to see it first hand. No bull, no political games, no assumptions.
