Raskosovka "Laurel": reviews. How best to use the "Laurel"?

During the operation of the power unit of the car, a part of the fuel-air mixture remains in the combustion chamber, which settles on the oil-removal and compression rings, as well as pistons and cylinders. Over time, this leads to the fact that the rings lie and do not fulfill their function. There is an increased fuel consumption and a decrease in the dynamic characteristics of the engine. In this case, you can use the excavation "Laurel". Customers ' feedback , advantages and disadvantages of the means, as well as the way to apply it, we will consider in this article.

Some general information

Currently, there is a huge amount of money to clean the car engine. There are both foreign and domestic producers who have proven themselves well. In this article I would like to talk about the domestic product for excavation - "Lavre". Reviews about it are more than positive, and many motorists prefer this washing. But I would like to note right away that if the motor of a vehicle needs major overhaul, its cleaning by "Lavrom" or any other similar means will not help. Only the overhaul will solve the problem here.

It is worthwhile to draw your attention to the fact that the excavation can be done by one's own hands. There is nothing complicated, although much depends on the design of the car. The more modern it is, the more time it will take. But they often perform excavations on motors that have already run fairly and are heavily soiled by carbon deposits. Usually, motorists perform washing independently, because this will save some of the money and make it all conscience.

About the reasons for the appearance of zakuskovki

First of all, I would like to understand in more detail what is contributing to the severe pollution of the motor. The fact is that during the operation of the car, very often you have to drive at low speeds. This leads to the formation of carbon deposits on the valves and walls of the combustion chamber. Although in fact, this is by no means the only cause of internal combustion engine coking, as there are a lot of them:

• Use of low quality fuel;
• Driving on a warm engine;
• Use of unsuitable power oil.

All this gradually leads to the fact that the deposit becomes more and more. Ultimately, the mobility of the compression and oil-removal rings is limited . This contributes to an increase in oil consumption, a deterioration in the dynamic performance of the engine and other problems.

Undoubtedly, the solution of the problem will be helped by the excavation of the "Lavrom". Customer reviews confirm this. Let's see if this domestic product is so good, how to use it and what not to forget.

"Soft" cleaning

There is one quite popular way of caring for your engine. Mostly suits the owners of new cars or those that have just undergone major repairs. The essence of the method lies in the so-called preventive "soft" cleaning of the engine. This allows maintaining the internal cleanliness of the motor for the entire life of the engine. "Soft" cleaning is a regular event, which must be carried out every 2-3 thousand kilometers. In this case, also used the excavator "Lavr", the reviews of which we will consider.

True, there is no need for any skills and abilities. All that is required of the driver is to add the "Laurel" to the fuel, observing certain proportions and intervals. As a result, a protective film is created in the combustion chamber of the power unit, preventing formation of carbon deposits during a certain time. If the procedure is repeated on a regular basis, then zakoskovki can not be afraid.

Unpacking of the engine "Lavrom": instruction, photo

Still, the more popular and topical method of washing the car engine is "hard" cleaning. The fact is that not all motorists regularly use detergent additives in fuel, and not everyone owns a new car. Low fuel quality and heavy operating conditions result in the engine becoming highly contaminated and losing its performance.

The first step is to get acquainted with the instructions for using the excavation laurel. Reviews say that it is the failure to comply with the dosage very often leads to sad consequences. It is recommended to pour 45 ml of liquid into the cylinders by the manufacturer of the washing, and immediately close the technological holes. This is done for the formation of a steam bath. Thus it is necessary to try to expose pistons approximately on one level and to leave a liquid for 1 hour. It is also recommended to rotate the pistons periodically.

After a few hours, it is necessary to unscrew the candles and close the technological openings with a clean rag. This is done in order to avoid getting the washing liquid on the car part. After that, for 5-10 seconds we turn the starter and so several times. In this case, it is advisable to press the accelerator pedal as far as it will go. This will lead to the fact that the remnants of the "Lavra" will completely exit the system. After that, we start the engine and let it run for 10-15 minutes at idle and variable gas mileage.

"Laurel", means for excerpt: consumer feedback

Already many motorists have tried this tool on their motors. Most drivers are positive about this washing. Nevertheless, there are a number of nuances that must be observed and what the car owners say. First, in order to avoid problems with the ignition system, it is recommended to remove the connector from the Hall sensor or short the central HE wire to ground. In any case, you can not allow the ignition of fumes because of the spark. Secondly, immediately after flushing, you need to replace the oil in the system. This is the required item for execution. The point is that the washing with the slurry settles in the crankcase. Accordingly, during work all this is mixed with grease, in which there is nothing good.

Most car owners plan to flush just before the maintenance. If you do all the work yourself, it's very budget-friendly. The above reviews and instructions can help the novice driver. Unpacking the engine "Lavrom" should also be done regularly to achieve the most optimal results. In some cases, it makes sense to repeat the procedure.

In details of the complete excavation

It is necessary to install the car in a horizontal position (as when replacing the oil). The vehicle engine must be warmed up to operating temperature. Without this, it will not be possible to achieve the effect of the steam bath. The next stage - the twisting of the candles or the removal of injectors, depending on the type of power unit (gasoline or diesel). Further, as already noted above, you need to put the pistons in the middle position. To do this as accurately as possible with a screwdriver, which measures the depth on which the piston is currently standing. Crankshaft can be turned manually by 5-10 degrees. We need this procedure so that there is no overspending of the "Lavra", and it spreads more evenly.

To dispense the "Lavra" it is best to use a syringe. If you notice that after a while the cylinder is emptied, you can add a little washing. As for the length of the excavation, there is no unequivocal opinion. Someone leaves according to the instructions for an hour, while other drivers for the best effect wash for 12-14 hours. Everyone should decide for himself. The effect of the "steam bath" will only last for the first time, but in very difficult cases it makes sense to perform a 12-hour excavation. After the candles are swirled, it is necessary to start the engine and allow it to work for a while (no more than 15 minutes), while it is advisable not to increase the speed above 2.5-3.0 thousand. The next step is to replace the oil and filter.

What problems can you face?

Far from always the process of excavation goes like clockwork. Nevertheless, this method is known for a long time. Undoubtedly, several other means were used before. For example, our grandfathers for excavation simply mixed acetone and kerosene in a 1: 1 ratio. In fact, the "Lavr" has a similar composition with slight differences. The fact is that after washing the combustion chamber from the walls of the cylinders, the oil film is completely removed. That is why the first engine start after the excavation can be called critical. When there was no specialized means, but used acetone and kerosene, this led to the appearance of scuffing on the pistons and other defects.

But modern means of such lack do not have, after all after their use on walls the oil film which protects system from the raised friction is formed. But many motorists still do not trust the composition and add some motor oil to the cylinders. There is nothing terrible in this, it will burn and fly out into the exhaust pipe. Sometimes it is quite difficult after the excavation to start a car. In this case, it is recommended to install a set of new spark plugs or burn old ones, and while they are hot, try to start the ICE. If necessary, the procedure must be repeated several times.

Another important

We have already sorted out a little with how the excavation "Laurel" is performed. What it is and how it works, you also know. But I would like to highlight a few important details, which are rarely spoken about. The point is that, ideally, the excavation should help increase the compression of the power unit. But sometimes the opposite happens - compression falls.

Often this happens on old engines with a significant mileage. The wear of the piston group in such an engine has long exceeded all standards, and the deposit acts as a seal between the cylinder and the piston. When the excavation is carried out, the deposit is removed. This leads to a drop in compression. Consequently, the overhaul of the power unit is approaching. Therefore, with 100% certainty to talk about the benefits of washing the motor can not. In one case, the excavation can significantly delay the overhaul, in the other - on the contrary.

What do drivers advise?

Ironically, many motorists prefer to use a "soft" excision. This is a less effective method and more time-consuming. Nevertheless, he does not require any effort from you. It is enough just to fill a certain amount of liquid in the fuel tank and drive further. Nagar, though for a long time, but still gradually burns, while the higher the load on the motor, the faster and better the washing process, at least, this is said about numerous reviews. The means for excavating the "Lavr" from the domestic manufacturer is inexpensive, but its efficiency is not worse than "Liquid-moth" or "High-gir", which are higher in price several times.

Moreover, motorists note that the "Lavr" is the most neutral to rubber seals and gaskets. But still do not use it too often, as the oil seals and old gaskets can not stand. But nevertheless it is necessary to understand that if there is too much output, then excision does not help. Yes, this method can delay the overhaul of the power unit, but in the end it can not be avoided.

Let's sum up the results

Nevertheless, the network is much more likely to receive positive feedback. Raskosovka rings "Laurus" really able to restore their mobility. But much depends on the condition of the power unit and the amount of carbon deposits. In some cases, in order to achieve more or less noticeable results, it is necessary to perform several washes in a row. Only then will the compression ratios increase, and the oil consumption will decrease.

Separately, a few words I would like to say about the complexity of the excavation engine "Lavrom". Reviews say that there is no problem on the in-line 4-cylinder power unit, then everything is somewhat more complicated with V-shaped engines. Of course, the essence remains the same, but to put pistons in about one position will be more difficult. Do not forget about the ignition, which for each unit is installed separately. In the rest, the procedure for excavating is similar to the above.

So we figured out the means of "Laurel", the instruction for washing and other important moments. If there is no time and the desire to independently engage in the excavation of the engine, then you can contact the car service, preferably checked. There specialists will perform a high-quality washing of the system. If the motor on your car is in-line, then this pleasure will cost you several thousand rubles. For V-shaped power packs a bit more expensive. Although it is better to try to cope on your own, because this requires a minimum of knowledge and tools. The main thing is to follow the instruction, which is written on the package "Lavra" and the sequence of actions. Reassemble in the reverse order. After the "hard" washing is recommended to install new spark plugs and change the oil.
