Drum roll...
140ml caught in just over 3000km.
It's doing something
After I made the vid I ended up positioning the catch can in a differnent place than the ones I mentioned.
I installed it in the front of the engine bay. Next to the right hand headlight.
I found this place enabled zero hose kinkage from the PCV valve, and back to the turbo inlet. The heavy gauge large fuel line I used for the hosing, actually supports the filter in place really well. Don't need any brackets.
Just one zip tie, self adhesive insulation foam for abrasion protection, it's held tightly and it's easy to service.
Cut the zip tie, undo the 2 hose clamps, twist a bit and it's out.
Last week during my swirl motor delete, I took off the turbo inlet pipe, and it was bone dry. Absolutely zero sign of any oil in that part of the intake.
