Hey mate. I have a 17 Crown with the 1Jzgte, already replaced the stock recirculation bov woth another one. That one didn't last long. So im going to also swap out for an aftermarket bov.
u can modify stock bow - there is a hole downside the bow - just setup an fitting on it and its starts work from vacuum like turbosmart but it's will be free ^_^
How did you get the hose to fit good enough around the 25mm fitting? I bought these parts to do this too and the hose measures 30mm so it's a decent amount bigger than the 25mm fitting
