What will you need?
- The first liquid is BG 109
- Second - Mitsubishi Shumma Engine Conditioner 250 ml.
Liquids may be of other brands, but this combination, as experience shows, is one of the best.
Step-by-step process for high-quality decarbonization
To decarbonize the engine, you will need two fluids, one to be poured directly into the engine oil, the other into the engine cylinders. To do this, open the neck on the cylinder head cover and, using a funnel, fill contents of the first jar.
Then we start the engine, raise the engine speed to 1700 rpm for 20 minutes. Then we switch the engine to idle mode and keep it running for about 1 hour. The benefits of the flushing fluid filled in are clearly felt, as the engine begins to run noticeably softer and vibration decreases.
Next, we move the gas injectors, disconnect the wires by pressing the latches, unscrew the 10mm wrench using an extension cord and the coil wrench on each cylinder, take them out and unscrew the spark plugs using a spark plug wrench.We pull the candles out of the wells using coils. The iridium spark plugs appeared to be in good condition.
We set the pistons in the cylinders at approximately the same height using any metal spoke and fill each combustion chamber evenly second means through a homemade extension cord from a hose. Tighten, but do not tighten, the candles and leave overnight.
In the morning, we unscrew the spark plugs again and use a medical syringe of suitable volume to extract the liquid poured the day before into a small transparent container.
It is very dark and thick in color due to oil and soot deposits dissolved in it.
Cover the cylinder head with a clean rag and ventilate the cylinders by cranking the engine with the starter. We repeat this process until no more contaminated liquid comes out of the cylinders. The more dirty the initially clean rag is in the end, the better the decarbonization of the engine went.
Next, use a clean soft cloth to wipe all the spark plug wells until they shine.
We wash the spark plugs in solvent 647, additionally clean them with a stiff toothbrush and wipe with a soft, clean rag soaked in the same solvent.
We install the spark plugs in place using a piece of hose. If you simply throw them into the well, you can shift the position of the side electrode, which is unacceptable. We clamp the candles tightly, but do not squeeze them, so as not to damage the ring that ensures the tightness of the candle in the thread.
We wipe each coil, install it in place, tighten the bolts and connect the wires. Initial attempts to start the engine may be unsuccessful because the combustion chambers contain many ingredients other than gasoline and air. There is no need to be afraid of this.
After several attempts, the engine will start, and abundant smoke will pour out of the exhaust pipe, the density of which will gradually disappear. After this, the motor will run even softer, and the vibration will practically disappear. All that remains is to drive the car 10-15 km and change the oil. This completes the decoking of the engine.
