I have a 2015 Honda Civic that has a tiny oil leak between the engine and transmission. The powertrain warranty will be expiring in 500 miles, and I was thinking that the leak maybe from the rear main seal. If so, would it be reasonable to expect thee dealership to pull out the engine and replace the seal for this tiny leak? I mean a leak is a leak, and the leak could only get worse, so why not fix it? One potential reason not to pull the engine out would be that bolts could be over tightened and mistakes could be made during removal and reinstallation. One example of this is how a dealership stripped my alternator Bolt without telling me on and older Civic.
