Is it serious to have engine oil in the intercooler?

[DiCollin]

Generally, it is not serious to have engine oil in the intercooler, but it needs to be analyzed based on specific conditions. The following are the reasons for engine oil in the intercooler intake pipe: 1. Internal reasons: prolonged engine idling, clogged or deformed crankcase ventilation system, and coking of lubricating oil in the turbocharger intermediate housing. 2. External reasons: driving conditions and maintenance can cause engine oil to enter the intercooler intake pipe. Below is an introduction to the intercooler: 1. Function: The intercooler's role is to reduce the intake air temperature of the engine. The exhaust gas from the engine is very hot, and the heat conduction from the turbocharger increases the intake air temperature. As air is compressed, its density increases, but this also raises the temperature of the air discharged by the turbocharger. While air pressure increases, oxygen density decreases, thereby affecting the engine's effective charging efficiency. 2. Classification: Intercoolers are usually made of aluminum alloy. Based on the cooling medium, common intercoolers can be divided into two types: air-cooled and water-cooled.
