My son-in-law (an engineer) and I recently did this job. The advice of leaning the engine forward seemed useless as you still cannot access the rear plugs well enough to change them (in my opinion). We went at them from underneath. If you have a lift, then you are in luck. If not, use ramps (we did). My son-in-law has smaller hands and was able to change two of the three from underneath. The one that is closest to the passenger side was changed in combo with him underneath and me from the side of the engine. Most of the work was done on this left rear plug from the side of the motor with the guy underneath helping. We also found that using a mirror on a stick helped a bit to get an idea of which way the plugs were angled etc. will do it blind and it will take you 2-3 hours for the rear plugs. We did not bother with the wires...we had new ones on hand but since the motor was running clean and smooth I opted out of the added frustration. I would say replacing the wires is a good idea however. We just weren't having any fun at this point! VENTURE: NO WONDER GM IS GOING BROKE.
