Engine Top Cover Gasket Leak Detection in Gasoline, Diesel and LPG Vehicles

It is a test kit that helps detect engine top cover gasket leaks or engine block cracks quickly, cheaply and clearly in vehicles running on gasoline, diesel and LPG.

Today, almost all internal combustion engines are water cooled. As fuel burns in the combustion chamber, the cylinder and engine heat up to very high temperatures. This heat is transferred to the cooling water circulating within the engine block. As the heated water passes through the radiator via the circulation pump, the radiator fan is activated and reduces the temperature of the water. The temperature sensor, which constantly measures the temperature of the water, is activated when needed and keeps the engine and engine cooling water constant at a certain temperature. In a normally operating vehicle, cooling water never enters the combustion chamber, and the gases formed by the combustion of fuel in the combustion chamber never mix with the cooling water.
- Malfunction of the temperature sensor
- Failure of the radiator fan
- Excessive strain on the vehicle
- Extremely hot weather
- Malfunction of the circulation pump
- not using antifreeze
- clogging of the radiator
- blockage/burst of coolant hoses

For a number of reasons, the engine cannot be cooled sufficiently and the engine cylinder head gasket burns/deforms and capillary channels are formed on it, causing engine gases to mix with water. These leaks may not have any effect on the performance or general condition of the vehicle in the early stages. If these leaks are not noticed and the vehicle continues to be used in this way, overheating, loss of water, loss of performance on hills and high fuel consumption begin to be observed. Despite all these indicators, it is almost impossible to clearly detect the leak. The surest way to eliminate these doubts is to remove the engine top cover and check the gasket. This process takes a long time and is costly.

So how does one detect leaks?
In case of leakage, combustion chamber gases quickly mix with the cooling water. The circulation pump carries the gases to the vehicle's coolant expansion chamber. When you vacuum the gases in the tank atmosphere, the test liquid in the kit, which is sensitive to combustion gases, turns green if the amount of gas is low and yellow if it is high when it encounters these gases. If the blue color does not change, there is no leak.
So, "Green Color" means that there is a small amount of leakage in your vehicle's engine and you probably caught the leak in the beginning. In this case, you must replace the cylinder top cover gasket.
If the test fluid turns "yellow", there is a serious leak in your vehicle's engine. You should replace the cylinder top cover gasket without delay and have the necessary checks made for block cracks.
