its the rear main seal, common on these cars. our blocks actually have seperate plates on front and back. on the back you need to remove the trans to get to it, then you can unbolt the plate with the main seal on it, put in a new one, and put it back together. Should take about 5 hours at the most ( working on the ground with no trans jack or all the proper tools.) but once you do that, your in top shape.
