How To Fix Milky Oil In Engine?

Step 1: Diagnose The Problem

The first step in fixing milky oil in your engine is to diagnose the problem. You can do this by inspecting your engine for signs of a coolant leak. Look for puddles of coolant under the car, or check the coolant level in the radiator or overflow tank.

Step 2: Determine The Cause Of The Coolant Leak

Once you have identified a coolant leak, you will need to determine the cause of the leak. Common causes of coolant leaks include a damaged radiator, a damaged head gasket, or a cracked engine block.

Step 3: Fix The Coolant Leak

Step 4: Drain And Refill The Engine Oil

After you have fixed the coolant leak, you will need to drain the milky oil from your engine and replace it with fresh oil. This will help to remove any remaining coolant from the engine.

Step 5: Run The Engine And Monitor For Further Issues
