THE ULTIMATE GUIDE HOW TO
Periodic inspection of the spark plugs is an uncomplicated but extremely important method for engine diagnostics. The working part of the spark plugs (vortect or any other engine)- the electrodes between which a high-voltage spark is formed, are located directly in the combustion chamber and collect on the surface all the "traces" of the work of the power unit. The presence of certain deposits experienced motorist can tell about potential problems with the motor. One of the most disturbing symptoms is the presence of oil on the candle.
Where will oil get on
The engine is designed to provide the necessary tightness of cooling and lubrication systems. Liquids circulate in their contours and cannot get into the combustion chamber. That is why traces of oil on the spark plug already initially speaks about certain problems. In this case, it is strongly recommended not to continue operating the vehicle, but to immediately turn to auto mechanics. Tightening the repair is fraught with deterioration of the motor condition and can lead to its complete jamming due to poor lubrication.
Oil leaks are associated with impaired tightness of those components and systems where it is provided for constructively. In this case, the lubricant may leak:
In the first case, the problem should be looked for in the wrong gaskets: cylinder heads or an oil filter. The second is not visually determined. It is to control possible leaks in the cylinders and applied diagnostics spark plugs.
Reasons for immediate diagnostics.
In addition to periodic inspections of the spark plugs, there are situations in which diagnostics should be carried out immediately:
For greater reliability, it is recommended to perform diagnostics on a new spark plug - their ideal (without traces of work) surface makes it possible to notice even the slightest traces of oil on the spark plug thread.
On a candle can be:
These symptoms (increment) indicate the degree of destruction of sealing elements. With a small amount of oil, the car troits and “shoots”; with large quantities, it often stalls or does not start at all.
Causes of oil falling on spark plugs
There are several engine assemblies from which oil leaks into the chamber can potentially arise:
Each of these problems is serious enough and can cause major repairs. In order not to aggravate the “losses”, it is not worth delaying with a more detailed diagnosis of the mechanic.
