Oil leaks are a common problem for motorists. Most of the time it is an easily resolvable situation. However, sometimes the cause could be a serious malfunction in the car's engine. Here are some simple guidelines to resolve this issue before going to a professional.
Steps
Step 1. Check the oil
Open the hood, remove the oil tank cap and extract the check rod. Clean it with a rag so you can see the minimum and maximum oil level marks. "Dip" the dipstick back into the tank to understand how much oil there is.
Top up if the level is low or insufficient. Keep checking every 30 minutes. If the leak is very rapid, then you may have a hole in the oil pan
Step 2. Use a fluorescent system to look for the leak
Combining blue or ultraviolet (UV) light with a fluorescent dye allows you to spot even the smallest losses. Add the color to the oil tank and run the engine idle for 10 minutes. Turn off the lights and turn on the UV one, you will see the fluorescent color that shines thus indicating the origin of the leaks.
Step 3. Sprinkle a light coat of talcum powder around the engine
Drive for 15 minutes. If you find oil on the surface, the talc will absorb it, so you can understand where it comes from.
Step 4. Check the oil circuit
Make sure the oil tank is full and start the engine. If the leak is located along the circuit, you will see the oil gush out when it is under pressure. You can replace the circuit or repair it with silicone tape.
Step 5. Find the oil pan gasket and remove all residues
Put a bucket under the drain valve, remove the cap and drain the oil. Put the cap back on and fill the cup again. If pooling forms along the edges of the cup, then the leak is from the gasket.
Step 6. Look for multiple losses
If the oil comes out of several areas, then the cause is the pressure inside the tank. Since there are many factors that affect pressure, you need to go to your mechanic or shop to diagnose the problem.
Step 7. Consider having the "steam" engine compartment cleaned to make leaks more noticeable
Wrap cellophane around connectors, sensors, and wiring; secure everything with adhesive tape. Spray some degreaser on the engine and let it work for as long as necessary and indicated on the package. With the help of a steam cleaning tool, it eliminates any residual grease and dirt. Dry the electrical components and sensors with compressed air.
Advice
- The fluorescent dye is available in many auto parts stores.
- To check for oil leaks it is best to wait 10 minutes after turning off the engine (cold check).
- The fluorescent dye remains in the oil system and can be useful for diagnosing future leaks, if necessary.
- You can rent the high-pressure steam cleaning machine at home improvement stores.
- Use a plastic and silicone-safe degreaser.
