But what do they do?
Fitted a catch tank a few weeks ago. Whilst doing it i cleaned the puc (pcv valve?) out. Even though there was a spring inside, im assuming part of a valve. I could blow through it both ways.
So thinking it was faulty i ordered a new one off Ebay. Seller had decent feedback and has sold 150+ of these.
Anyway, it turned up today. Got a spring inside but i can still blow through it both ways.
Am i missing something? Is it not supposed to be a 1 way valve?
