I've located the O2 sensor in my 318 in the driver side manifold. The problem is that it is recessed and difficult to get to. Is there a special tool ( similar to a transmission line wrench ) that can ease in removal?

Yes they do
most autoparts places carry a specific O2 sensor socket the RC use a 7/8"

i was able to use a wrench from underneath. autozone will loan the tool for about $15 and you get the $$$ back when you return it.
