Ok guys after beating my head in the wall. Trying to stop the massive oil down of rear of valve cover. I figured out the problem. Hope this helps all you others out there. Fixed mine so far. For a sum of $14. I’ll attach photo of breather I bought and goes right into grommet. What I believe to have been happening. Is when it was ran to bottom of Webber carb air cleaner. The fresh air inlet was put behind filter.
Instead of pulling in fresh air. When carb opened up. The vacuum through carb was creating a vacuum causing the carb to pull oil mist back through fresh air inlet, Getting it all over valve cover and engine bay. Oreillys is where I purchased mine.
