Does it matter if the intercooler has engine oil?

It generally doesn't matter if the intercooler has engine oil, it should be analyzed according to the specific situation. The following are the causes of engine oil in the intake pipe of intercooler: internal causes: the engine runs idle for a long time, the crankcase ventilation system is blocked or deformed, and the lubricating oil in the intermediate housing of turbocharger is coking. External reasons: The reasons for oil in the intake pipe of intercooler include driving conditions and maintenance. The following is the introduction of the intercooler: Function: The function of the intercooler is to reduce the intake temperature of the engine. The exhaust temperature of the engine is very high, and the heat conduction through the supercharger will increase the intake temperature. The density of air will increase in the process of compression, and the temperature of air discharged from supercharger will increase. With the increase of air pressure, the oxygen density will decrease, thus affecting the effective inflation efficiency of the engine. Classification: intercooler is generally made of aluminum alloy. According to the different cooling media, commonly used intercoolers can be divided into air-cooled and water-cooled.
