Hey guys, I am having a problem finding the correct breather. I've been using a push in which is not correct for this style valve cover. I tried a ford motorsports screw tab breather from Summit and Mustangs Unlimited with no luck, would not sit correctly. I rigged this up with a couple push in grommets. It does not work well but is my temporary fix until I find the correct breather. I recently tried gluing the PCV grommet in last night on the other side. Any of you have an issue with finding the correct breather and PCV part to fit in these valve covers correctly? They are the ford racing covers which are pretty common for the aftermarket. It seams like my holes may be larger than what's on the market unless I am trying the wrong parts. Thanks!

 

i'd try that one

I'm about 95% positive that's what I tried... wondering if I should try again in case it wasn't. That would be the same bottom view where the tabs screw in but if I recal the tabs weren't long enough
