How to install spark plugs in a 3100 gm engine

On the 3100 engine in most GM cars the spark plugs on the rear of the engine are not that visable. Here is an ideal for putting the spark plus back in with out stripping the spark plug hole assuming that you are replacing the wires also. When installing the new spark plugs in the rear of the engine it is mostly by feel because you cant see the hole, so with that in mind.Take one of the old spark plug wires and pull the spark plug boot off off it, also remove the meatal conector from inside the boot.Now you can use the boot for an extenssion, put the new plug in that boot and you can start the plug in the hole. this is a good trick you can tell if the plug is going in staight or if the plug is not in at all. After you start the plug in tighten it as much as you can before pulling the boot off and tightening the rest with a socket. hope this helps.
