Hi all b6 passat 2.0t 85k stock,I have only just heard of a catch can.. do i need one/ do they help keep valves clean? is it easy to install? is there another pcv fix. i need to call VW To see if there are any RVU'S for my VIN, it is not under factory warranty, i brought it at 79k dont know much about its service history except some oil changes, brakes a two tires, i saw on the car fax report, i did purchase 2yr/24000ml service plan, $250 deductible, anyone have one of these "devices" or should i just make sure i have the latest pcv, thanks for any and all information/advice.
