There are two hoses on the hood of the car leading to the throttle. What pipes do they come from?
This is the crankcase ventilation hose. When the cylinder burns and explodes, part of the gas leaks into the crankcase from the gap of the piston ring, resulting in too high pressure in the crankcase, which is easy to cause oil to seep from these places of the oil seal. The vacuum tube connected from the valve cover to the intake manifold forcibly sucks the exhaust gas from the crankcase into the intake manifold, and is afraid that the pressure in the crankcase will be too low due to the excessive vacuum of the intake manifold, so an extra tube is added to the intake hose (there is no vacuum), so that the pressure in the crankcase can always be kept in the best state.
