I am having a similar issue. SO, m question is... how can oil come from anywhere concerning the bellhousing? Is that what you meant by 'getting into a oil passage'?? My leak is showing up on both sides if the engine. Does this mean that I might have more than one bellhousing bolt causing problems? I am also considering the idea that the distributor gasket is compromised in some way... If anyone sees this, please let me know.
