I would do the exploratory surgery as well.
Take engine out, take front cover off, inspect things under there.
Then if not any problems found there its rebuild time. The least you'll need is new coolant seals.
But I wonder how the hell does an oil jet from the e-shaft even make its way to the oil pan?
Makes me think its got to be from something under the front cover.
