Recently when I was cleaning the TB and IACV I took out the breather hose from the crank case. I noticed there was a wire inside so I thought it wasn't supposed to be there and proceeded to take it out using the stubby end of an antenna.

Well it turned out to be a thin metal wire with wire brush on the end. It was held in place by the fact that the hose itself was a bent shape. Is this thing there to prevent/filter deposits being spit back out from the crankcase back to the intake path? Did anyone else notice this brush-like filter in their hose?

My wife's '88 Nissan PU has one, and it is supposed to be there. Don't know about my '97 SE, I'll check in the morning.

 

Cool thanks...let me know when you find out. I ended up not putting it back in cause I wasn't sure. So far didn't notice any difference with drivability/idling.

 

i took mines out and its been about 8 months, no problems noticed from removing the wire brush.
