About 10k miles ago, I had my clutch replaced. The shop also replaced my rear main seal as preventative maintenance. They only charged me for the part and they even gave me the old one. Now black oil is seeping through the hole at the bottom of the clutch housing and around the rubber seal on the clutch slave cylinder. Its not dripping yet but there is oil on the outside of the clutch housing. Is this unusual for a new RMS? The car has 52k miles.

It's a bad seal. Don't know why they changed it to begin with.
