fresh air hose
can i take it off without hurting anything? i know the crankcase needs vacuum but can it get all it needs from the pcv system? i unhooked the fresh air hose while the car was running and i didnt feel much vacuum at idle from the tb. the reason im asking is its getting a decent amount of oil in the intake. i assume from blow-by. i was just gonna cap the port and put a breather in the valve cover

i think what happens is at high rpms the pcv valve cant keep up so the pressure relieves the easiest way which is through the fresh air hose. i installed one of those filters where the grommet goes in the cover and seems to be working
