Yeah im curious about that part too, i went to autozone and orielly and they just have the "rattling" kind. Ive heard the new one is built different that other, im not really sure exactly though. I would like to get any info too.

I think it is PN#12572717 but not sure.

 

Their also was some other info I am looking for that was in a post that talked about this.

But I can't find the post.

the new pcv valve simply has a small hole in the end

a fixed size so a small volume can pass through it

any dealer should have it you won't find it anywhere else
