Hi all thank god its Friday. Just wondering if anyone can help. How do I go on about checking to see I my pcv valve is faulty. I've spoken to someone at a Peugeot dealership what a waste of time that was and they said that you can buy a replacement kit, but then other people have said you can't buy a kit the pcv valve is incorporated into the rocker cover and you have to change the whole thing. Easier said than done if I could find somewhere who sells the rocker cover for my engine. I have a 2010 200bhp. How can I check the valve to see if its passing oil. Also is it worth buying a catch can for my car.
