here's the production studio setup

the jar at the back is plumbed between the lower crankcase breather and the PCV towards the inlet mani
whilst the jar closest is between the air filter/turbo inlet and the upper crankcase breather entry at the top of the engine cover.
in this clip I'm mostly just cruising around under light load keeping under 60mph.
you can see that since the inlet mani's under vacuum most of the time, it sucks all the hazy vapours from the crankcase, some vapour condenses inside the rear catchcan (working almost immediately u can see it begin condensing 2mins after starting up), goes through the PCV and into the inlet.
the jar in front is mostly clear cos most of the time it's just cool clean air from the filter flowing through towards the upper crankcase entry, so nothing to condense. the only time there's a hint of vapour is when I'm accelerating on boost and the flow reverses briefly.

so after just 45miles of cruising the crankcase to inlet jar has condensed this much vapour

next I'll be driving back home with more boost and at 70mph.
notice that when I'm at/above 0psi, the +ve boost shuts the 1-way PCV so the hazy blowby that was flowing through the rear jar stops flowing n remains still,
meanwhile the excess blowby vapours now exit the crankcase out the other way via the upper breather port, through the jar in front hence it begins to mist up during boost.
when I lift off after boosting, the inlet vacuum opens the PCV, the flow suddenly reverses back to normal, clean air rushes back through the front jar so it clears up,
the hazy vapour that was in the front jar then travels through the crankcase, through the rear jar so it resumes hazing up, then back into the inlet mani.

after 60miles it's collected this much

on closer inspection here's the empty front jar from the air filter to upper breather port

and here's the rear jar from crankcase to inlet mani, just look at the milkshake
