plug change
I have a 91 vette with 27K miles. L98 vin 8 engine. According to the FSM i am due a plug change. I thought i would do it my self until i started looking for them . WOW , what is the secret to getting at them. Looks like pulling the engine would be easier.

Its not that bad, with the right tools. It takes me 45 minutes to an hour, taking my time, to swap plugs on my 85's L98. I use a sidewinder wrench on plugs for cylinders 2 and 4 and an adjustable head 3/8" drive on the rest. Some guys go thru the wheel wells for straight access.
Take your time and you'll get the job done. Remember to check the condition of the old plugs and correctly gap the new ones and put anti-seize on the threads.

I have two different spark plug sockets - one has a built-in universal joint. I have a number of different extensions of various lengths along with other U joints. With the right collection of tools, the job is do-able (but not easy

Thanks for the info guys. Is there any advantage to coming from underneath for some of them. Years and years gone by I had a 59 Vette and one plug was a lot easier when it was up on a lift.

Right side, is the problem, taking them out, with extension and universal, is the trick. NOW installation is get yourself old rubber hose, that fits the spark plug perfect, and then slide it on, screw it in the best you can, and pull the hose off, and set your socket to tighten.

Actually, I use the hose trick for all the plugs. It helps to avoid cross threading.
