Same here. Ive posted a link to another topic on this forum with a lot of the same information I spent hours researching. My truck blew a rear main seal, oil cooler line, and blew out the silicone on the oil pan and RMS housing. Shit like that doesn't happen unless there is a damn good reason. The reason I was told and have found to be true is an over pressurized crank case.
Also with doing the research I also learned exactly HOW the PCV system works and how the valve itself works. Understanding that it's spring loaded and its operation correlates with load and RPM also tells me that unless you're running at 4K RPM at all times you really aren't pushing that much ventilation from the crank to your intake.
When I removed my catch can and installed the old PCV system, I noticed the same kind of condensation build up in the bottom of my throttle body as what would accumulate in my catch can. I emptied that can every 1000 miles. It never got full but it would get 50-75% full in that time frame dependent on temperature and usage. When installing that catch can I never had puddles of anything accumulating in my TB. I didn't take a picture as I don't typically think posting it for Instagram or to a forum when working on things so the "evidence" is solely upon my eyes only which may be a travesty with this topic and others regarding catch cans.
Anyway, I quoted you but hope Jacoby reads this post as well. I mean no ill will with posts. I post with the purpose to express my experiences in hope that it saves people time and money and maybe even expensive repairs. I don't think that most people post with the intent to viciously hurt someone. But, as well all know, ignorance toward how vehicles work and peoples mechanical aptitude can really shift a majority of people in a dangerous direction, like maybe installing a catch can where it's not needed.
Good day to everyone.
