I was considering getting this: Airaid PCV Breather
But I wasn't sure if it would fit the Fiero V6? Summit racing's website is really vague in the details, does anyone know what size PCV breather I should get? By the way I'm looking to put this on the FRONT valve cover, since my tube for the front PCV is disconnected and I can't seem to reconnect it.

The hole size the filter needs look larger than the fiero one so you would have to adapt. You can verify by checking the PCV hole since it's the same size on both covers.
If you are worried about the size of the filter you can move the PCV to the rear cover and change the tube to it easily, then locate the filter of the rear cover.

dodge runner they are quite a bit different i just replaced both of mine
the back one furthest away is smaller.

Interesting, what year? I know my 85GT they are the same...I had the grommets out when I painted the covers and put them back in the wrong holes, had to reverse them. Unless the PO had somehow replaced parts.

yes mine is a 85 and i got the new ones from the fiero store.
and mine is still very original. yup just went out and checked the
second set i bought and they are different.

I just used the breather that AutoZone sells in their "tuner" parts section. Right next to the hot air intakes.
I swapped the grommets front to rear (mine were different sizes) and moved the PCV valve to the front valve cover. I put the breather in the rear valve cover where it will be less likely (I hope) to get water dumped on it.
