I don't think I would want to hook to crankcase. Very likely to change vacuum levels and mess with tuning. Would be better to return directly to oil system, but even that would be tough to control.Might be a way to remove excess fuel from oil- primo bypass filter has a heating chamber which will remove fuel and water from oil -similar to other remote bypass filters except has this additional heating chamber which gets oil in chamber up to 195 to evaporate fuel/water before returning clean oil via gravity to crankcase.They are sort of universal type fit so you would need to be a diy type or have someone install it for you- I think cost is around $350 -google primo bypass filter for more info and a retailer.
Block heater or driving your car harder for a few miles would probably easier.
Edit: Also $350 is worth 10-20 DIY oil changes.
