are all honda pcv valve the same and are they interchangeable as in using a b18c pcv in a h22a motor because they look the same except for the part number. my h22a pcv valve is clogged and i happen to have a spare one for a b18c and wondering if you can use it in the h22a. thanks

 

I'm not sure if they are. But they are so damn cheap why not just pick up a new one?

 

im in australia and parts for honda's aren't cheap over here.
