Breathers are working fine for me...

Some like to contribute to global warming, others are trying to slow global warming.

And those folks trying to slow it buy Prius'....you won't find many of them on a forum dedicated to 8-cylinder performance cars (half of which have removed emissions systems).

Breathers here..no oil residue at all. Just some oil smell once and awhile.

Why not get a breather can

I'm running Bobs. It's a nice piece with drain valve on the bottom.

I need an opinion here. Will I get enough flow out of a singe -10an teed from both valve covers to properly vent the crank case? I know that is larger than the factory lines put together... Looking at using this...

Cans don't stop all the oil, a lot still makes it into your intake. Oil = detonation, detonation = windows in engine blocks.

There's a difference in what he is mentioning, a catch can such as brand "J" is still routed back into the intake, but a breather can simply vents the vapors into the atmosphere through the filter and is not routed back into the intake. It's pretty much like having the breathers on the valve covers but it has something to catch the oil. So, no oil in the intake and no chance of anymore detonation (well, from the PCV system anyways lol)
