What purpose do filters on oil catch cans serve if boost and vacuum run through them? Wont they reduce or cause the boost vacuum to exit the system?

 

pretty sure they are there for more looks than actual function but the could help in releiving some pressure for the can itself

 

You just reminded me...i need to get a catch can....

 

Ur welcome but anyone else? Ahh ---- it, its not Im going to use a filter on em neways

 

I use one so I don't send boost into my crankcase.

 

Sounds like yours is setup wrong, might want to rethink it.

 

+vac source should be pre-turbo...

 

i would run it with out a filter. if there is a filter on it i would think that there would be little to no vaccum unless the filter is really restictive. if you are running a catch can with filter i dont see how it would be any better than if you just ran a strait filter

 

unless you'd like to suck up all the oily ---- commming from your crank case...you should use some sort of filtering media. I don't understand where everyones input about filter media creating vaccum and so on. Maybe you should search and figure out exactly how you need to set up a catch can system...and figure out what the exact purpose is so that you can better understand it.

 

I ran a filter on mine, but it wasn't hooked up to any source where it would see boost or vacuum. The filter was just to let the vapors escape.
