Replacing rear spark plugs on a 3100 V6?

atikovi · 03-29-2022, 10:02 AM

I picked up a very nice N body 1995 Skylark and will be changing the plugs. Most online videos show people removing 2 front dog bone engine mounts and ratchet strapping the top of the engine forward to access the plugs, but this car doesn't use those mounts. What's the best way to get more access?

It's my understanding that the way to do this is with a bunch of different sized extensions, and probably swivel adapters, using a magnetic spark plug socket, and going mostly by feel since you aren't going to be able to see what you are doing. I'm referring to the 3400 engine, but it might work out the same on the 3100.

I just removed the coil pack on top of the engine for better access.

That is pretty a given on these cars for a lot of procedures.
