What will happen if the oil return pipe of the car is blocked?

At present, most EFI vehicles are equipped with oil return pipes, but this device is rarely seen in classic cars, so many drivers don't know what it is used for and how to deal with problems. If the fuel return pipe of a car is blocked, the air-fuel ratio during fuel injection will not be well controlled, and the most intuitive manifestations are the difficulty of starting the car, unstable idle speed, engine jitter, engine flameout while driving, slow throttle response and so on.

Once the oil return pipe of an automobile is blocked, we need to check and eliminate it immediately, otherwise it will not only accelerate the sudden decrease of the service life of the automobile engine, but also affect the aging of the parts of the oil supply system. Adding special detergent to automobile fuel is the simplest method, but it is not durable and the cleaning effect is not particularly ideal.

When using fuel cleaner, remove the carbon deposit in the automobile oil circuit and its accelerator. The cleaning effect of this method is detailed, but the money and time spent may also increase accordingly. Connect the oil inlet pipe and oil return pipe of the engine with the corresponding pipeline of the disassembly-free cleaning machine, so that a loop will be formed, with obvious cleaning effect and convenient operation.
