Don’t Let Oil Ruin Your Ignition Coil: Expert Tips on How to Get Oil Out of Ignition Coil

What to know

  • The ignition coil is a vital component in your car’s ignition system, responsible for generating the high voltage needed to ignite the fuel-air mixture in the cylinders.
  • Similar to the crankshaft seal, a failing camshaft seal can allow oil to leak from the camshaft, potentially reaching the ignition coil.
  • Oil is a conductor of electricity, and its presence on the coil can create short circuits, damaging the coil and other electrical components.

Have you ever encountered the dreaded sight of oil leaking onto your ignition coil? It’s a common problem that can lead to misfires, engine hiccups, and even complete engine failure. If you’re wondering how to get oil out of ignition coil, you’ve come to the right place. This comprehensive guide will walk you through the process, step by step, so you can get your engine back in tip-top shape.

Understanding the Problem: Why is Oil Leaking?

Before we dive into the solution, it’s essential to understand the root cause of the oil leak. The ignition coil is a vital component in your car’s ignition system, responsible for generating the high voltage needed to ignite the fuel-air mixture in the cylinders. Oil shouldn’t be anywhere near the coil. If you find oil on or around your ignition coil, it usually indicates a serious problem.

The most common culprits for oil leaks near the ignition coil include:

  • Valve Cover Gasket Failure: The valve cover gasket seals the top of the engine, preventing oil from escaping. If this gasket fails, oil can seep out and find its way to the ignition coil.
  • Crankshaft Seal Failure: The crankshaft seal prevents oil from leaking out of the engine’s crankshaft. If it fails, oil can leak onto the engine’s lower components, including the ignition coil.
  • Camshaft Seal Failure: Similar to the crankshaft seal, a failing camshaft seal can allow oil to leak from the camshaft, potentially reaching the ignition coil.
  • Oil Pressure Relief Valve Failure: The oil pressure relief valve regulates oil pressure within the engine. If it malfunctions, it can lead to excessive oil pressure, causing leaks in various areas, including around the ignition coil.

Why You Need to Remove Oil from the Ignition Coil

Oil on your ignition coil is a serious issue for several reasons:

  • Misfires: Oil can contaminate the ignition coil’s electrical components, leading to misfires and poor engine performance.
  • Short Circuits: Oil is a conductor of electricity, and its presence on the coil can create short circuits, damaging the coil and other electrical components.
  • Corrosion: Oil can attract dirt and grime, leading to corrosion on the coil’s metal components. This corrosion can hinder the coil’s functionality and eventually lead to its failure.
  • Engine Damage: A faulty ignition coil can lead to engine damage, as misfires can cause excessive wear and tear on other engine components.

The Tools You’ll Need

Before you begin the cleaning process, gather the following tools:

  • Shop Towels: To absorb oil and clean surfaces.
  • Degreaser: A specialized cleaner designed to remove oil, grease, and grime.
  • Brush: A small brush to help scrub away stubborn oil and grime.
  • Compressed Air: To blow away loose debris and dry the coil.
  • Protective Gloves: To protect your hands from oil and chemicals.
  • Safety Glasses: To protect your eyes from splashes.

Step-by-Step Guide: How to Get Oil Out of Ignition Coil

Now that you have the necessary tools, follow these steps to clean your ignition coil:

1. Disconnect the Battery: Before you start working on any electrical components, always disconnect the battery to prevent electrical shocks.
2. Locate the Ignition Coil: The ignition coil is typically located on top of the engine, near the spark plugs. Consult your car’s owner’s manual for the exact location.
3. Remove the Ignition Coil Wire: Carefully detach the ignition coil wire from the coil.
4. Clean the Coil: Use a shop towel to wipe away any visible oil. Apply degreaser to the coil and use a brush to scrub away stubborn oil and grime. Be sure to clean all crevices and nooks.
5. Rinse and Dry: Rinse the coil thoroughly with water or a cleaning solution. Then, use compressed air to blow away any remaining water or debris.
6. Inspect for Damage: Carefully inspect the coil for any signs of damage or corrosion. If you find any damage, the coil may need to be replaced.
7. Reconnect the Coil Wire: Once the coil is completely dry, reconnect the ignition coil wire.
8. Reconnect the Battery: Reconnect the battery and ensure that the engine starts and runs smoothly.

Addressing the Root Cause: Beyond Cleaning the Coil

Cleaning the ignition coil is a temporary solution. To prevent oil from accumulating on the coil again, you need to address the underlying problem causing the leak.

  • Inspect the Valve Cover Gasket: If the valve cover gasket is leaking, you’ll need to replace it.
  • Inspect the Crankshaft and Camshaft Seals: If either of these seals is leaking, you’ll need to replace them.
  • Check the Oil Pressure Relief Valve: If the valve is malfunctioning, it may need to be replaced or repaired.

Preventing Future Oil Leaks

Here are some tips to prevent oil leaks from recurring:

  • Regular Oil Changes: Change your oil regularly according to your car’s maintenance schedule. This helps keep your engine clean and prevents oil from breaking down and leaking.
  • Inspect for Leaks: Regularly inspect your engine for any signs of leaks, including around the ignition coil.
  • Replace Worn Parts: Replace any worn or damaged seals or gaskets promptly to prevent leaks.
  • Use High-Quality Oil: Using high-quality engine oil can help reduce the risk of leaks.

The Final Word: A Clean Engine is a Happy Engine

By following these steps, you can effectively remove oil from your ignition coil and restore your engine’s performance. Remember that cleaning the coil is a temporary solution. Addressing the root cause of the oil leak is essential to prevent future problems. With proper maintenance and care, you can keep your engine running smoothly for years to come.

Questions We Hear a Lot

Q: Can I use brake cleaner to clean the ignition coil?

A: While brake cleaner can effectively remove oil and grime, it’s not recommended for cleaning ignition coils. Brake cleaner can be harsh and can damage the coil’s electrical components.

Q: What happens if I ignore the oil leak on the ignition coil?

A: Ignoring the oil leak can lead to serious engine problems, including misfires, engine damage, and even complete engine failure.

Q: How often should I inspect my ignition coil for oil leaks?

A: It’s a good practice to inspect your ignition coil for oil leaks during every oil change.

Q: Can I replace the ignition coil myself?

A: Replacing an ignition coil is a relatively straightforward task that many DIY enthusiasts can handle. However, if you’re not comfortable working on your car’s electrical system, it’s best to consult a qualified mechanic.

Q: How long does an ignition coil typically last?

A: Ignition coils can last for a long time, often 100,000 miles or more. However, their lifespan can be affected by factors such as oil leaks, extreme temperatures, and electrical surges.
