What Are the Consequences of Oil Emulsification?

[TravisFitz]

After oil emulsification, the performance of the oil will decline, and an effective oil film cannot be formed between internal engine components such as crankshaft bearings, camshafts, connecting rod bearings, pistons, and cylinder liners. This leads to poor lubrication and accelerates wear on these components. Emulsified oil contains excessive water and produces more harmful substances, which can corrode engine parts. After oil emulsification, the engine noise may increase, and the engine malfunction indicator light may illuminate. If oil emulsification occurs, the following repair methods should be applied: 1. If oil emulsification is detected, the first step is to check whether it is caused by coolant entering the oil, whether the oil cooler is damaged allowing liquid to enter the oil, and whether the crankcase ventilation valve is functioning properly. 2. Check if there is a gasoline smell in the oil. If any of the above components are found to be faulty, the damaged parts should be replaced first, followed by cleaning the engine lubrication system to remove all emulsified oil, and then replacing it with new oil.
