Ok dual webber carbed 2.0, I think the PO had the head vents running to a T then to the oil breather near the oil cap... Is this right?? I did a search and now I'm really confused,,,,

You could do what the V8 drag racers use. Crank case vacuum scavenger tubes welded to the exhaust. They create negative pressure in the crank case and help to seat the rings better and reduce blow by. This setup is not legal to run on the street but know one really checks for this set up. To use it correctly you will need check valves on the scavenger tubes. You would also run a sealed case, no vents other than the valve covers.
