Does a broken ignition coil burn oil?

A broken ignition coil doesn't directly cause oil to burn. ‌ The main function of the ignition coil is to convert 12V DC electricity on the vehicle into tens of thousands of volts of high voltage for spark plug ignition in the engine combustion chamber. It is similar to a small transformer, but the operating environment is more demanding, because the engine operates at higher temperatures and requires thousands of fires per minute. The damage of the ignition coil usually leads to the loss of car power, lack of cylinder, jitter, increased fuel consumption and other problems, which is because the spark plug can not be ignited normally, resulting in incomplete combustion of the combustible mixture of gases, resulting in carbon deposition and black smoke. However, the damage to the ignition coil is not directly related to the phenomenon of burning oil.

The main reasons for burning oil include aging or damage of valve oil seal, resulting in oil infiltration into the combustion chamber; The piston ring is worn or damaged and cannot be effectively sealed; As well as too much carbon inside the engine, affecting the normal circulation of oil. These problems will cause the oil to enter the combustion chamber, mix with the fuel and burn, resulting in the phenomenon of "burning oil". Therefore, while damage to the ignition coil can cause a range of engine problems, it does not directly cause burning oil.

There's oil in the ignition coil. What's going on？

There is oil in the ignition coil due to leakage from the valve chamber cover pad. The material of the valve chamber cover pad is mostly rubber, which will inevitably become old and hard over a long time, so there will be oil leakage. Solution: Replace valve chamber cover pad.

The valve cover is on the top of the engine, and the oil leaking out will flow down the cylinder, and the temperature of the engine working is very high, which will directly evaporate the oil on the cylinder block, producing a pungent smell. Valve chamber cover gasket is mainly used for sealing to prevent oil leakage. Pull out the ignition coil and see that there is oil on it, it must be the valve chamber cover pad leaking oil, which needs to be replaced in time. If not treated, the ignition coil will always be soaked in oil, and its life will be affected.
