Ford Crown Victoria Spark Plug Parts Questions & Experts Answers
Q: How to inspect a spark plug for issues such as bridged gaps, deposit buildup, oil or carbon fouling, and signs of overheating on Ford Crown Victoria?
A: An inspection of the spark plug must check for a bridged gap along with the identification of deposit buildups that would close the electrode gap due to oil or carbon fouling. Check the cleanability of the spark plug when deposits are observed. Check the spark plug for oil fouling by identifying wet black deposits on the insulator shell bore electrodes since excessive oil entries result from worn rings and Pistons or excessive valve-to-guide clearance or worn or loose bearings and immediate resolution of oil leakage with new spark plug installation. Black dry fluffy carbon deposits on insulator tips as well as exposed shell surfaces and electrodes necessitate spark plug cleaning because these signs indicate incorrect heat range or soiled air cleaner or too much fuel or too much engine idling time. The inspection for normal burning should identify light tan or gray deposits found on the spark plug firing tip. Engine damage becomes evident when melted electrodes along with damaged insulator surfaces show metallic deposits that may stem from untimely ignition timing and wrong fuel selection or heli-coil installation by unauthorized personnel. Therefore, new spark plug installation becomes necessary. Spark plug replacement is needed if white or light gray spots or a bluish-burnt appearance of the electrodes is detected because overheating might result from engine overheating or the wrong fuel type or loose parts or incorrect heat range plugs or low fuel pressure or off-time ignition settings. The presence of fused deposits should be checked since these melted spotty deposits that look like bubbles or blisters usually form during sudden acceleration but you should clean the spark plug when these deposits exist.
