I did not remove the distributor.
One thing though, the engine seems to use more oil than it used to, and it will puff blue out the exhaust when restarted after it stumbles and stalls.
Ok based upon that you almost certainly have a bad intake pan gasket on the kegger. Look down the throttle body inside the intake. If you can see oil this is your problem. It will cause the motor to use oil and have a vacuum leak. Exactly what you are describing.
There are aluminum plates out there available to replace the stamped sheet metal piece on the bottom of the intake to make sure it does not leak again.
