What are the symptoms of engine blow-by?

Symptoms of engine blow-by: Difficulty in starting the engine, insufficient power, and when the blow-by is severe, the engine cannot start or run. Common locations for engine blow-by include blow-by from the valve cover and blow-by from the crankcase oil filler port with white smoke emission. When encountering engine blow-by, the first step is to use a cylinder pressure gauge to check the cylinder pressure of each cylinder. The pressure difference between cylinders should not exceed 10% of the average value. Hazards of engine blow-by: 1. When the blow-by exceeds the specified value, it will lead to increased power loss; 2. Due to the high temperature of the blow-by gas and the inclusion of substances such as dust and aluminum oxide in the intake air, it accelerates component wear, increases oil viscosity, and turns the oil black; 3. The temperature of the piston and piston rings rises, causing the lubricating oil in the ring grooves and on the rings to burn and stick, resulting in the piston rings losing elasticity and becoming stuck or breaking.
