Me thinks the Valiant had a signifenct oil leak onto the passenger headers, I'm sure you survive that run or you wouldn't be posting the picture. Did you get the oil leak or the cause of all that smoke corrected? If so what was it
It was a valve cover leak. I had the valve cover off just before that pass. They were cork and didn't like to be taken on and off. It ruined a good picture. Fixed it by getting better gaskets but don't remember which ones. That picture was from around 1995.
