Hello Bronze Bird, Yep, stock valley pan. I have a feeling that some of the smoke may be from me messing with the PCV valve and removing the grommet. Either way, I am getting some smoke floating back in the car when I get on it. I would not call the amount excessive, but if I can find someone who has tried the PCV valve I am hoping that may fix it. Then I wonder whether to just put the valve in my valve cover and plug the valley pan opening or put it in the valley pan and put the breather back in my valve cover. Thanks...….
