Gregg,

Was the head leaking really bad before you changed it? I've had exhaust systems with enough coolant dumped inside they take a good drive and heating to burn off completely. I had an S4 I did turbos on that smoked for a week from the oil in the cats.

The link to the video didn't work for me.
