Does your aluminium expansion cap release the pressure? I dont think so, they designed the oem very well.... dont do this guys there is a reason why does it crack and not because its plastic .... you supposed to change the cap to be working properly. Catch can FTW or replace whole ccv system every 90.000 km BUT for OEM!!!! By whole I mean CCV valve and all 4 houses and UN clog the dipstick tube to the oil pan thats it, never had any problem.
