total rookie move here, im used to havin room in an engine compartment. how do you reach the rear plugs and wires on the back of the motor to change them on a 93 regal

3.1 liter, they make a tool that takes the place of the dogbones (the mounts on the front of the engine that mount above the radiator) that allows you to pull the engine forward to gain some access. The mounts usually have a notch with a hole in them that will allow you to pull the engine forward and put the bolt through the hole to hold the engine in place.

3.8 - Its tight but it can be done. If it has the bar that mounts in between the struts it makes it a little easier to remove it. Not sure if a 93/regal has it or not.
