I picked up a quattroporte couple months ago, did a fresh oil change, checked all fluids, gear oil etc etc and I decided to take it out today since it was sitting for a week in the garage. In the morning it was fine, drove over 40 miles, parked it for about 2 hours, start it and a bunch of whit smoke came out and went away, drove it for 20 miles, parked it for an hour, start it and crazy amount of white smoke that took a bit till it cleared out. Took it home, and check the oil which it was changed 200 miles ago, and it’s milky white... is it the head gasket? Oil cooler problems? Or is it like how German cars in the cold they get milky? Any openions? Greatly appreciated..
