Oil Catch Cans

[Slidewayz]

Im just wondering does a oil catch can have to have a breather put onto it or not?

as far as i know it is illegal to have a catch can with a breather. you are allowed to have one without a breather.

gasses go to atmosphere. must be kept within the engine. i know this is fact in WA

Breather is a silly idea on a street car.

Traffic + hot day, yuck.

Just plumb it back into your intake pipe so it won't affect your idle.

Yeah its all to do with emissions - illegal!

Mine is plumbed back, however you can "still" have a breather on it, just dont get caught really!

plumbed back will save alot of hassels.

if you really want one tht isnt plumbed back just run the plumb back line down to where it should go, i know on a 33 you cant see if its hooked up or not.

It does if you dont plumb it back in. You have to vent the crank case air somewhere. If you plumb it back in, it then becomes an oil/air separator. Thats what you want if you run your car on the street, or the cops will get you for an epa.
