Keep the oil topped up, change the filter once a year until you get it fixed. Having said that the winter, when you plan on fixing it is right around the corner. Don't over think it.
to track down everything would require dropping the transmission from under the car, and also dropping the entire front suspension and subframe while also supporting the engine from above (to get the oil pan off). It will be easier to pull the whole engine and trans out, and separate them on the floor so that I can check around the rear main seal and flywheel bolts, which I may not have done correctly last time.
