Crazy question but I'll ask anyway...
Is there any chance OE valve covers originally had a mesh material inside the PCV baffle like the attached photo? Or is this simply someone's attempt to reduce oil mist from being sucked into the intake?
I realize it's highly doubtful, I only ask because I have seen this more than once on original used SB covers. In fact, I've seen it enough that it made me wonder...
Thanks,
Dave
