Things I might need to replace to stop this leak?
 

The leak if you don't know already is coming from behind the DIS rotor housing. When I get behind there, what is it that I might need to replace? I don't want my car off the road too long. I figure I would get what I might need ahead of time(if it is not to expensive) so I can fix it right away and get my car back on the road. Thanks for your help.

You have a camshaft seal leak.

Not technically difficult, but it has a high "oh ****" factor. You are going to need a 32mm Wrench (big one), and either a hex head or cheesehead socket on a good sized breaker bar, and an extra pair of hands.

Send me an email, I have the exploded view of the assembly
