Have a gasket burn test done. For 20 or 30 liras, the result is obvious in 20 30 seconds.
When the cylinder head gasket is generally destroyed, or when the cylinder head and gasket or the block are exposed to extreme temperatures, the metal bends, turns or does not change in time antifreeze drinking or tap water or completely The gasket between the block and the upper cover due to use without antifreeze cannot hold the pressure created by the pistons. This is called compressor leakage. The pressure formed in the combustion chamber mixes with the engine cooling water. This causes external expansion in the cooling system, causing the water hoses to swell. However, exhaust gas mixes into the cooling liquid. Compressor leakage The vehicle loses traction because some of the power of the piston or the pistons escapes. I would like to add the following information that your vehicle is dyn with 120hp. o test measurement is different. In the dyno test, the power that the vehicle transfers to the ground, that is, to the wheels, is measured. The vehicle manufacturers determine the hp without the drivetrain. That is, even if it is a brand new vehicle, the dyno is lower than the factory data. Here, the temperature, humidity, the used engine oil, the pressure lining, the gearbox situation, ignition system etc. are the factors that increase or decrease the hp.
