Does it affect the car if the exhaust pipe on the valve cover is pulled out?

There are two pipes: one is the valve chamber from the intake hose to the valve cover, and the other is the valve cover to the intake manifold, both of which cannot be pulled out; The first is the unplugged air that directly enters the engine, causing oil pollution and other hazards. The second is the real dragon tube, which will improve the speed a lot.

The first one is connected with the subsequent air branch pipe, and this end has a PVC valve (also called crankcase forced ventilation valve), which is a one-way valve. The exhaust gas generated by the crankcase is pumped into the intake branch pipe and burned by the vacuum negative pressure generated after the other end is connected with the intake branch pipe.

The second one is for air intake, and the other end is connected to the bellows connected to the throttle valve of the air grille, which is directly connected to the atmosphere.

Extended data;

If the exhaust pipe is not connected with the exhaust valve, it will be impossible to control the circulating amount of exhaust gas, and too much exhaust gas will participate in the recirculation, which will affect the ignition and performance of the mixture, thus affecting the dynamic performance of the engine, especially when the engine is idling, low speed, light load and cold engine.

The main function of automobile exhaust pipe is to pump out the engine exhaust gas under certain working conditions, and send some exhaust gas discharged by the engine back to the intake manifold, and then re-enter the cylinder together with fresh mixed gas to participate in combustion and do work, so as to achieve the purpose of improving emissions.
