Just goes to show how useless all the "catch cans" and other devices on the market are in comparison.




Yes, but it also depends on how heavy breathing your engine is. Our results found that engines which were worked/chipped/etc had more blowby and put more soot into the oil - which means the filter blocks at a much faster rate. So rather than 250 kW (for OE-spec engines) I would suggest that a 200 kW limit is more sensible (for engines which achieve the 200+ kW by "tuning").
How likely is 200+ KW though, that's over 260BHP! Figure that's pretty much at the extreme end of TD5 tuning.
