    I have an oil leak or two I need to find before I tear I to mine. If I get into the back one I will replace packs and coils. Right now I have to many other projects. My ac is not working right so I will drive my explorer until it cools down.

    If you have had a rear one go, its normally a good idea to change the entire rear bank. Others back there will go soon, so it saves you a ton of time and effort to just do them all back there at once. If you are buying the low cost ones such as have been mentioned, I would do the fronts too just so you have a single date they all went in, but it does tend to be the rears that go first much of the time.

    If you want, I can e-mail you a document (word) that will help you with many photos of the surge tank from the rear.

    I'm running Visteon too (4 on rear and 4 cheapers on front) and they work good. Best quality for the bucks I have seen 2 years ago.

    For your rear wiring harness, as you don't want this become a money pit, I suggest you this :

    As you go there, watch if you have oil in plug wells, you can need seals for them (F6DZ-6F048).

    I replaced the bad one and all is well again. I don't know what I was thinking but I bought 10 so I could replace all 8 and have some spares..if I ever tear into the back ones I will replace them. Might wait until it is a necessity or I have spare time.

    If you take the rear off you may want to take it a step further and remove the valve cover to measure your gaps. I'd imagine you are over 100k and it's a good time to be monitoring this. You could also take the time to replace the valve seals which if never replaced are nice and hardened. Of course this is a lot of work to add to the simple venture. Just a suggestion to reduce time back there.
    Also as other mentioned get something to protect the wires from the valves more. Many melt or may very likely already be exposed to the elements.
    Fusable link tape works great for a patch. Of course nothing beats running new wire in those cases as the connectors may also be cracking.

    While you have things off check behind the power steering pump at the water hoses. The plastic "Y" connector frequently cracks, and should be replaced.

    Finally inspect your Hall sensor harness as it too gets exposed to a great amount of heat with little proper shielding.

    If you like simpler things (I just realize that I'm adding another step to this long list...), I add the suggestion to replace your upper alternator bolt to one without a stud and rewire the ground on a lower surge tank support bolt.

    Then your next alternator replacement will take you less time (and you will probably have to change an alternator on it sooner or later).
