Plastic PCV valve vs Metal PCV valve?
My plastic PCV valve is working fine but I thought I’d buy an original NOS in-bag L351 metal PCV valve for authenticity. The wider plastic PCV valve appears to work better than the metal one, much more air flow and a much better seal when you blow into the carb side end. The plastic PCV valve also makes more noise when you shake it.
