Transverse mounted engine? Apply parking brake and place transmission in 'neutral' (engine off of course). You will see a 'dog bone' engine mount in center by radiator. Remove the back bolt (I think). Place a bar in the lift bracket and rock the motor forward enough to place the bolt back in the next hole. This will tip the engine forward enough to reach the back 3 spark plugs. It's still a tight fit, but it helps.
Hope this helps.Changing spark plugs/wires on 1994 buick regal custom, 3.1 engine.?
you will also need a thin walled socket to fit the plug regular sockets will not fit between shield and plug

Changing spark plugs/wires on 1994 buick regal custom, 3.1 engine.?Just use a small angled pry bar to remove the 'heat shields' that are around the plug. These help shield the spark plug wire boot from the heat given off by the exh manifold.
Chilton Manuals are worthless. Purchase a Haynes manual.

The 3100 SFI is a very common power platform for GM, it's been in many many models and is still being produced today. By no means do you need to %26quot;rotate%26quot; the engine to get to the back plugs. I did get a good chuckle from the comment however ;)
It may seem impossible but I can assure you it's not. I've personally changed the plugs on at least 30 of those suckers. Some vehicles are more difficult than others (the 3100 in a Chevy Malibu tops them all).
You'll need the right tools for the job of course. A swivel attachment for your ratchet (driver) can be of great assistance when trying to reach plugs on the back side of an engine. Other than that you'll have to fight with it a little bit. If I recall climbing into the engine compartment (knees on the intake) makes it a bit easier to get your tools/hands onto the back side of the engine. You can also attach the spark plug socket to the plug first and then attach the ratchet, this is often times easier than trying to attach the ratchet/socket at the same time.
Good luck...and please, don't ever try and %26quot;rotate%26quot; an engine ;)
