Doc, regarding the spark plugs, I read somewhere about access being available via removal of the front plates in the rear tirewells. I looked on mine and it does appear the section directly in front of the tire which makes up part of the black surround comes out. Is this a good way to change the plugs I do have access to a lift and I have seen the way from underneath, just wondering about the other access..

It is by far easiest to put the car in the air and do it from underneath. You may be able to reach through the wheel wells, but to me it seems that is a lot more work than just putting the car on a lift, or on a set of jackstands and crawling underneath. From below it is a straight shot.

Hey DOC
Great write up

Have a question about the spark plug tube. The left rear cylinder head is coated with some oil blow by. I was told by the Dealer during my PPI that the spark plug tube needs to be changed? Is this hard to do or is it as easy a pulling the old one off and sliding the new one in. Also should I replace all of them or just the one that is leaking? Lastly do I need special assembly lube?

Thanks
GW

Once the spark plug is out of the hole, you need a pair of pliers or a sharp angled pick (a big one). They are a real bugger to get out some times, and you pretty much end up destroying the old ones trying to get them out (at least that has been my experience). Each tube has 2 o ring seals on it, one on each end (different part numbers btw). When you go to put it all back together, coat the o rings with silicone lubricant, and they should pop right in.
