When diagnosing the engine yourself, listen to its operation and pay attention to the color of the exhaust gases. These indicators will help you assess the technical condition of your car's engine.

Step 1
If you find a suspicious sound, make sure it relates to your car's engine and not other parts of it. Eliminate transmission and transmission noise by depressing the clutch pedal. While rocking the engine connected to the car frame with elastic cushions, listen to the suspension, crankcase and exhaust system of the car.
Step 2
Remove the alternator belt and check if the sound it makes is related to extraneous noise. Remember that loud knocking sounds at the top of the car indicate a necessary adjustment or increased wear of the valve train.
Step 3
Noises emanating from the middle and bottom of the vehicle when revving up indicates a serious engine problem. They warn of increased wear on the piston system, liners or crankshaft journals.
Step 4
A ringing metallic sound when a car accelerates or when the engine speed of a stationary car rises sharply is referred to as knocking knocks. Prolonged driving with such a defect leads to the destruction of the motor. Eliminate the malfunction, which can be caused by low-quality fuel, early ignition, engine overheating or a decrease in the volume of the combustion chamber due to carbon deposits on its walls.
Step 5
Pay attention to the condition of your vehicle's exhaust gases. A bluish smoke with a burning smell signals that oil has entered the combustion chamber. Remove the spark plugs and inspect them carefully.
Step 6
If traces of oil are found on the threaded joint, replace the valve stem seals or valve guides that are worn on high-mileage vehicles. If smoke comes out of the exhaust pipe all the time, and not only during gas overloads, check the parts of the piston system.
