Oil catch can questions..

[DatSRBoi]

What the the inside of a real oil catch can looks like? Is there a filter inside it?
Also I see people who has the head exhaust fumes run into the catch can and end it ther with a filter rather running another line from the can to the intake. Doesnt having it run to the filter help aid in sucking out the hot air? And since we are V6 and there is another head exhaust fume outlet in the back right under the manifold, would it be safe to run both the front and back into a catch can?

Thanks...Wanting to invest in one to keep the oil out of my manifold and my new intake coming in soon..

it has some wires inside it to trap oils. you see people have a filter at another end because they dont want the oil get sucks into the intake maniford. they rahter want to dump the oil out when it is full. that is the whole purpose of oil catch can.

I second that.
It prvents oil being sucked into you intake.
Cause you never know if that little drop of oil will end up in your throttle body.
