How to inspect the terminal post, insulator, spark plug boot, and spark plug recess area for damage and proper function on Chevrolet Corvette?

Question

Accepted Answer

Thoroughly check the terminal post to confirm its structural integrity as well as the tightness of its connection by twisting and pulling it because the terminal should not move. An inspector should check the insulator to detect flashover along with carbon tracking and soot formation that occurs through electrical charge paths from the terminal post to ground. Check for boot damage while inspecting the Spark Plug recess area whether it has moisture from oil, coolant or water since waterlogged boots can lead to ground arcing. Check the insulator for any present cracks that can cause electrical charge to short circuit instead of traveling through the electrodes (3, 4). A poor arcing condition requires assessment along with a measurement of the gap space between the center electrode and side electrode terminals to prevent Spark Plug malfunction. The wrong Spark Plug torque choice will cause operational issues but applying too much torque can break the insulator . The technical specialist must inspect the insulator tip region for tracking instead of the center electrode area while testing if side electrode and center electrode are intact through Spark Plug shaking; rattling sounds indicate internal breakdown and loose center electrodes lead to reduced spark energy. A detailed inspection must check whether electrode (3, 4) associations exist and examine the condition of platinum pads on electrodes (3, 4) where present. Observe the recess area on the Cylinder Head for debris since damaged threads or debris can stop the Spark Plug from installing correctly.
