Spark Plug: Description and Operation
1997 Oldsmobile LSS V6-3.8L VIN KSECTION Description and Operation
DESCRIPTION
The spark plugs are the resistor type with a tapered seat. No gasket is used on these tapered seat plugs.
NOTE: Always use 6-point deep socket (with rubber insert) in good condition when replacing spark plugs. When setting the gap on a spark plug, use a wire type feeler gage and make the gap adjustment by bending the ground (side) electrode.
SPARK PLUG LIFE
The spark plugs have platinum pads welded to the electrodes. These pads extend the spark plug life to 160,000 kilometers (100,000 miles).
IDENTIFICATION
The spark plugs can be identified by the "ribless" porcelain insulator. This "ribless" insulator and boot design provide a better plug-to-boot retention. The spark plug and boot design significantly reduces carbon tracking and reduces engine misfire.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
