You have to take out your transmission, clutch, and flywheel to get to it. It's a seal around the back of your crankshaft at the back of the engine block. If you do this job check your clutch for oil on it that also goes for the flywheel. Might be a good time to just replace a few things like pilot bearing, throw out bearing, and clutch while everything is out. That info is mainly if you have a the seal itself isn't hard to replace but getting to it is tiring and time consuming.
