There could be many reasons why the engine has no spark. A few reasons could be that the starter or starter solenoid is going bad, or the battery is drained.
this is normal, when the car is cold or off. the oil sinks down in to the oil pan.,. If this is a GM engine you may be using an aftermarket oil filter that allows oil to drain back this is not a good thing and can cause engine damage. GM has a TSB on this very problem.
It would be best to get a copy of a GM factory shop manual for any W car that uses this engine and carefully follow the procedures described. There are 2 things that will make this job easier however. Lisle makes a tool that allows you to compress the rocker arms so the push rods can be removed (they pass through the lower manifold) without disassembling the rocker arms. They also make a tool that will allow you to rotate the engine forward making this job easier and provide access to the rear spark plugs. Also be sure to use the GM gasket upgrade kit and new manifold bolts and torque exactly to spec. Follow the procedures exactly as it is easy to assemble things out of sequence making the next step difficult or impossibles. I have successfully done this job at home and all fluid leaks were corrected. But it does take an entire day or 2. It is important not to treat these engines like an old iron V8. Stay away from them with the old air wrench.
Keeping the plug wire out of the way, Start the engine. In a few minutes the engine pressure should push out the porcelain center from the plug. At this point you can use a tool called an easy out to remove the threaded part of the plug.
Depends on the engine. On Ford V8 it is passenger side front, on GM V8 it is driver's side front.
take the front grill support off if the engine is in the car. then remove the plate covering the cam. then remove the cam?. it is alot easier with the engine on a stand.

Gm Dex Cool or equivalent. The red color antifreeze.
That engine is pushrod, it is the GM 3100 if I'm not mistaken. What are symptoms because bent valves are unlikely.
The GM 3.1 litre V6 engine has a timing CHAIN
The General Motors 3100 family of after 1996 underwent a changeover to interference designs. This standardized GM powertrains design across multiple platforms such as the 3400 and 3500.
That would be the 3ed spark plug from the front on the drivers side head.

The 1994 GM A Body vehicles with the 3.1 requires 41 to 47 psi for fuel pressure.
There are some comments that you should not adjust the gap sizes of the plugs and use them the way they come out of the box. Hmmm .. I have a 1999 Grand Prix GTP with the 3.8L V6 supercharged engine. My GM owners manual states a gap of .060 for all the replacement plugs listed not only for my engine but for all Grand Prix engine sizes of that year 3.1 / 3.8 / 3.8SC Check your GM owners manual .. it will state there in the section of different replacement parts, what spark plugs to use and the gap size
A GM 2.4 liter engine in a 98 cavalier should have a spark plug gap of .050. The plugs may come pre-gapped, it is still a good idea to check them.
1 gm = 1000 milligrams therefore 3.1 gm = 3100 milligrams
as your standing in front of the car, on the right side of the engine bay, behind the exhaust running along the right side of the engine (again, as your looking at it from the front of the car.
