98 Z34 Rear Spark Plug Change

[emba129]

I have a 98 Monte Z34 with 3.8L. Car has only 53K mi. I am thinking of replacing the spark plugs even though they are 100K plugs. Not so concerned about the plugs themselves as I am about being able to remove them at 100K. The car is going on 8 years old and I would like to at least remove them, put anti sieze on them, clean and reinstall them.

What is the best way to remove the rear 3 plugs, from top? or bottom? Do you have to rotate engine?

Please help..
Thanks Chris

It's probably easier from the top, and rotating the engine forward makes it much more accessible. As long as you have the plugs out, it might make sense to replace them, as your labor is worth not having to do it again a few years donw the road. Get some good platinum-tip plugs; Wal-Mart sells them cheap.
