Question about 2002 Pontiac Montana
There are two ways to replacing the 3 rear spark plugs.
1. You can remove the two dog bone engine mount in front of the engine bay and tilt the engine forward, so you can reach the spark plugs over the top of the engine with extension and swivel with the ratchet.
2. You can jack up the front end up and go from the bottom of the van. Your going to also need to use extension and a swivel with the ratchet and have to work by feeling your way around.
Careful not to damage the spark plug wires if your not going to replace them.
Good luck and be safe, the easiest way for you to tilt the engine forward is to place the transmission in park and place the parking brakes on with a block in front and behind the back wheels. Disconnect the dog bone engine mount, remove the block from the front of the back wheels. Take the parking brakes off and push the Montana forward and this will tilt the engine forward. Once tilted, place the parking brakes back on and relocate the block to the back wheels.
Follow the instructions in revers to connect the bog bone once again and be safe, better that you have someone help you tilt the engine if your going to do the #1 method.

You need to drain some coolant. Loosen and disconnect water lines by the firewall- the ones in the way of your wire change. u need to get a diagram of the firing order of the engine so that those wires are correctly connected to the coil packs.

SOURCE: Spark plugs difficult to replace
The engine does need to be shifted to replace the rear plugs, but it is easy. Take out the dogbone engine mount in the front of the engine compartment and push the vehicle backwards while still in park , then throw the parking break on once the engine tips forward.

the spark plug hole need to be repaired and the smoke is probably due to the spark plug begin pushed out...combustion gas...

Inspect for the correct routing of the spark plug wires. Improper routing may cause cross-firing. Inspect each wire for any signs of cranks or splits in the wire. Inspect each plug wire boot for tearing, piercing, arcing, carbon tracking or a corroded terminal.
If there is any corrosion, carbon tracking or arcing indicated on a plug wire boot or terminal, both the plug wire and component it was connected to should be replaced.
