I'm curious to see what advantages/disadvantages there are with either my current setup or putting filters on the intake and exhaust side of the valve cover while plugging the holes on the intake manifold and intake tube.
my current setup........
edit: I'm just tired of seeing oil in the intake that inevitably coats the intake valves. I'm not sure if this will cause a lean code because the air venting through the valve cover wouldn't be metered with breather filter mod. I know race engines use a vacuum pump and catch cans but my engine doesn't make any more power above 6000 rpm so pulling a vacuum on the crankcase wouldn't be beneficial over just venting to atmosphere (at least that's what I assume). I just don't want to have to constantly clean my throttle body from the blow by.
