just wonderin , who acually puts a filter on top?, i was gonna start ventin mine to under the car cause my one been gettin cloged up with crap? its like its suckin air in? so just vent it under the car save gettin oil over the clean rocket cover.
If you've still got the PCV valve connected to the inlet manifold, then air will be pulled in through the breather when the valve opens. That's the reason for having a filter on the breather.
should i vent both to under the car then? says on td04 complete list of mods that u need to vent 1 and leave a breather on the other? lol dont say what 1
