For the first year I had my 911 I ran dino oil and had no leaks.
I then switched to Shell synthetic and I developed a leak onto the passenger side heat echanger within three days. It rarely hits the groud but it does stink and smoke a very small amount.
i just finished replacing the valve cover gaskets, crank case vent hose and gasket, the pressure sender, thermostat o-ring and oil cooler seals, hopefully the leak will go away.
