Are you sure that there wasn't a lot of oil sitting in the bottom of the lower intake manifold?Everything is up and running, but have a lot of oil behind the throttle plates now. I have added an oil separator (drivers side), and don't see oil in the exit.
There is a vacuum tube on the elbow (just behind the throttle) that goes down in a hole (it looks like) into the wheel well?
What is this line? Vacuum can? Can it be plugged without side effects?
Any other ideas where the oil can be coming from?
