I need some help. A few months back I noticed a slight oil leak coming from the seal right behind the crank pulley. I was under the XK last night and noticed that its getting worse. I priced the seal at the dealer and its going to run me about $11, however they mentioned its a lot of work just to replace that seal. Does anyone have a service manual for an 07 XK with 4.7 liter that can post the instructions so I can look over them before I do it? Thanks
