so i got my STi coupler in
and i am building the air oil separator system witch i can put in soon once my plastic fittings come in
mann hummel provent 200 and i welded a nipple for the drain back on my stock dip stick tube. you need a one way valve and i got high temp o rings for the provent 200 lid.
the hose is a bmw 1990 325 6 hose witch has a step in it the same size as the provent 200.
