Can anyone tell me if the from crankshaft seal is replacable without breaking the crankcase apart. I was replacing the flywheel and when I removed the flywheel cover the entire inside of the flywheel cover was covered in oil. After cleaning it up I noticed the crankshaft seal was in slightly crooked (pushed out slightly more on the bottom). I have done quite a bit of automotive work and without thinking much about it figured a new seal would just press in. I ordered one and after it arrived I see there is a hump that goes around the outside, which got me to thinking about whether it was replaceable without disassembling the engine. Any advice is appreciated.
