CCV Delete / bypass / re-route or catch can

I recently replaced the cold side intercooler pipe and deleted the throttle valve. In doing so, I noticed a lot of oil in the pipe. So, I started doing research. It looks like the OEM Ford Crank Case Vent unit allows some amount of oil to circulate back through the turbo. Supposably by design.

I have found articles / videos in favor of all 3 options. One guy (mechanic) is adamant that the factory fixes issues that are brought to him.

I just don't see how sending oil back through the turbo is a good idea. Adding oil to the air system just seems counterproductive.

So I looked at the oil catch systems or the reroute system.

What do you guys think or what is your experience?

The CCV isn't designed to send oil back thru the intake. That's just a horrible way the process ends up effecting the motor.

How I understand it all: CCV is a feature needed to prevent the crankcase from getting over pressurized. I have read that there is more blowby at idle than when under load as it's the piston rings that cause the biggest part of this problem.

A catch can isn't a bad idea when applied correctly. A reroute system to vent to the exhaust may not have the "as designed" flow to pull the "blow by" out of the head area.
