I was wanting to change valve cover gaskets on my 2001 4.4. The passenger side was relatively easy because you can actually change it without removing the ignition coil box that connects to the fuel injectors. However, the driver's side appears to be a different story. The TIS doesn't outline about how to gain any slack from the positive battery lead and suggests that it just lays under the ignition coil box. From what I see it runs deep into the bowels of the intake manifiold area. Are there any special instructions for removal of the battery lead to get it out of the way? The TIS also doesn't mention any special instructions about moving the ignition coil box out of the way. It just shows in the picture that it's gone. I read somewhere on the web that there are special clips which hold the box to the injector. Is that really the case, if so the TIS doesn't mention it. Anyone have any advice before I dive into the driver's side?

Thanks.
