So about this time last year I was doing an oil change and noticed oil hanging from the bottom of the transmission housing. Took my ST to the dealership and they diagnosed it at the rear main seal and it was repaired under warranty. Just got under my car today to do an oil change and guess what? Rear main seal is leaking again in less than 7k miles. This time my clutch is feeling like it's slipping so I'm pretty sure it's fouled. Any ideas of what would make the rear main seal fail repeatedly?
