Very often, owners of cars with high mileage have to deal with annoying knocks from under the hood. In fact, this does not indicate any serious damage.. Probably, here we are talking about hydraulic lifters, which in turn are designed to perform a specific function.
Hydraulic compensators - these are special devices, by means of which the valve clearances of the power plant are adjusted. They are presented in the form of a tube, inside which the plunger pair is located, check valve and spring.
Whatever it was, checking and replacing hydraulic compensators in a car is a rather responsible process, the implementation of which must be treated with the utmost care and seriousness, because only in this case can you count on getting the maximum effect.
As we have said previously, Hydraulic compensators mean hydraulic mechanisms, thanks to which it becomes possible to set the required valve clearance under extreme temperature conditions. In case of excessive heating of the power plant, its internal components increase, which in turn leads to a reduction in gaps.
If we talk about the correct operation of this device, here motorists do not have to deal with any extraneous knocks or other situations. But if there is even the slightest knock, we have to talk about the wear and tear of this device, which in turn leads to increased fuel consumption and early valve burnout.
Before you begin checking the functionality of these devices, it is necessary to first understand the main reasons, capable of causing their malfunction.
- First of all, All internal components of the car are subject to natural wear and tear during operation.. And all because, that they are forced to come into contact with each other regularly, resulting in a violation of the tightness of the system.
- Secondly, in case of excess or lack of lubricant in the crankcase of the power unit. In this case we have to talk about compression as the oil itself, and air, contained in it.
- Thirdly, in case of excessive contamination of the internal components of the mechanism. The thing is, that over time, particles of metal and dirt appear on the surface of the device, which in turn leads to various interruptions in its operation.
If we talk about a worn hydraulic compensator, it makes strange sounds when the engine is running. Therefore, in order to make sure that these parts are broken, It is mandatory to use a phonendoscope. After comparing sounds, you can detect malfunctioning devices in a matter of time, and also establish the location of the defect.
To replace hydraulic compensators yourself, you must have all the necessary tools and other devices on hand.. However, it is important to remember, that this is an important and responsible process, which requires strict adherence to certain rules. Therefore, if there is any doubt, It is better to seek help from experienced specialists from the very beginning.
