Used Plugs Tell A Story 1. Normal Combustion deposits are slight and not heavy enough to cause any detrimental effect on engine performance. Note the brown to greyish tan colour, and mini mal amount of electrode erosion which clearly indicates the plug is in the correct heat range and has been operating in a healthy engine. 2. Worn This plug has served its useful life and should be replaced. The voltage required to fire the plug has approximately doubled and will continue to increase with additional miles of travel. Even higher voltage requirements, as much as 100% above normal, may occur when the engine is quickly accelerated. Poor engine performance and a loss in fuel economy are traits of a worn spark plug. 3. Carbon Fouled Soft, black, sooty deposits easily identify this plug condition. This is most often caused by an over-rich, air-fuel mixture. Check for a sticking choke, clogged air cleaner, or a carburettor problem float level high, defective needle or seat, etc. This may also be attributed to weak ignition voltage, an inoperative pre heating system (carburettor intake air), or extremely low cylinder compression. 4. Splash Fouled Appears as spotted deposits on the firing tip of the insulator and often occurs after a long delayed tune-up. By-products of combustion may loosen suddenly when normal combustion tem per atures are restored. During hard acceleration these materials shed from the piston crown or valve heads, and are thrown against the hot insulator surface. 5. Oil Fouled Too much oil is entering the combustion chamber. This is often caused by piston rings cylinder walls that are badly worn. Oil may also be pulled into the chamber because of excessive clearance in the valve stem guides. If the PCV valve is plugged or inoperative it can cause a build-up of crankcase pressure which can force oil and oil vapours past the rings and valve guides into the combustion chamber. 6. Fuel Additives Red to purple deposits on one side of the core nose are an indication of a fuel additive. While many of these deposits are non-conductive and do not contri bute to lack of performance, some additives contain octane boosters 7. Ash Fouled A build-up of combustion deposits stemming primarily from the burning of oil and/or fuel additives during normal combustion... normally non-conduc tive. When heavier deposits are allowed to accumulate over a longer mileage period, they can mask the spark, resulting in a plug misfire condition. 8. Pre-Ignition Usually one or a combination of several engine operating conditions are the prime causes of pre-ignition. It may origin ate from glowing combustion chamber deposits, hot spots in the com bustion chamber due to poor control of engine heat, cross-firing (electrical induction between spark plug wires), or the plug heat range is too high for the engine or its operating conditions. 9. Detonation This form of abnormal combustion has fractured the insulator core nose of the plug. The explosion that occurs in this situation applies extreme pressures on internal engine components. Prime causes include ignition timing advanced too far, lean air-fuel mixtures, and insuffic ient octane rating of the gasoline. 10. Overheated A clean, white insulator firing tip and/or excessive electrode erosion indicates this spark plug condition. This is often caused by overadvanced ignition timing, poor engine cooling system efficiency (scale, stoppages, low level), a very lean air-fuel mixture, or a leakage intake mani fold. When these conditions prevail, even a plug of the correct heat range will overheat. 11. Insulator Glazing Glazing appears as a yellowish, varnish-like colour. This condition indicates that spark plug temperatures have risen suddenly during a hard, fast acceleration period. As a result, normal combustion deposits do not have an opportunity to fluff-off as they normally do. Instead, they melt to form a conductive coating and misfire will occur. 12. Mechanical Damage May be caused by a foreign object that has accidentally entered the combustion chamber. When this condition is dis covered, check the other cylinder(s) to pre vent a recurrence, since it is possible for a small object to travel from one cylinder to another. This condition may also be due to improper reach spark plugs fitted. 1 2 3 4 5 6 7 8 9 10 11 12
