I have a 2006 Ford Fusion SE (2.3L 4-cyl.) 5-speed Manual, with 280,000 miles on it. It's been a great car with very little repairs, etc. I've noticed a little oil on the driveway - nothing big, but certainly consistent. At my last oil change, they told me I had a leak in the crankshaft seal and that I should take it to an engine shop. I'm not a 'do it yourself' kind of person when it comes to big repairs. So I'm wondering if it's an expensive fix and worthwhile? I'd love to keep the car going another year... but don't want to end up spending a ton of money on it. What do you think? If I don't fix it, should I avoid oil changes? The leak doesn't seem bad and it doesn't drive any different.

Thanks.
