Common Causes of Oil Leaks After Service

• Loose Oil Drain Plug: One of the most frequent culprits is an improperly tightened oil drain plug. During an oil change, if the plug isn’t tightened sufficiently, oil can seep out.
• Damaged Oil Filter: A cracked or improperly installed oil filter can also lead to leaks. This is especially true if the filter wasn’t seated correctly or the old gasket wasn’t removed before installing the new filter.
• Damaged Oil Pan: If the oil pan was accidentally struck or damaged during the service, it could develop a crack, leading to an oil leak.
• Loose or Damaged Valve Cover Gasket: The valve cover gasket seals the gap between the valve cover and the cylinder head. If this gasket is loose, damaged, or improperly installed, it can result in an oil leak.
• Disturbed Existing Leak: Sometimes, a pre-existing, minor leak that was previously unnoticed might become more pronounced after a service, due to the car being moved or components being disturbed.

Diagnosing the Oil Leak

Identifying the source of the oil leak is crucial for effective repair. Here are some steps to take:

1. Check the Oil Level: First, ensure the oil level is adequate. If it’s significantly low, it confirms a leak and highlights the urgency of the issue.
2. Inspect Under the Car: Park your car on a clean surface and look for oil drips or puddles. The location of the leak can provide clues to its source.
3. Examine the Oil Drain Plug and Filter: Carefully inspect the oil drain plug for tightness and the oil filter for any signs of damage or leakage.
4. Trace the Oil Trail: Oil leaks often leave a trail. Follow the trail upwards from the puddle to pinpoint the origin.
5. Consult a Professional: If you are unable to identify the source of the leak, it’s best to consult a qualified mechanic for a thorough inspection. The car service cost perth or in your area will vary, so it’s best to shop around.

Solutions for Oil Leaks After Service

Once the source of the leak is identified, the solution can range from simple fixes to more involved repairs.

• Tighten the Oil Drain Plug: If the drain plug is loose, simply tightening it to the correct torque specification can resolve the issue.
• Replace the Oil Filter: If the oil filter is damaged or improperly installed, replacing it with a new one is necessary.
• Repair or Replace the Oil Pan: A damaged oil pan might require patching or replacement, depending on the severity of the damage.
• Replace the Valve Cover Gasket: A leaking valve cover gasket necessitates replacement.
• Address the Underlying Leak: If a pre-existing leak was exacerbated by the service, the underlying issue needs to be addressed.

“Addressing oil leaks promptly is crucial,” says automotive expert, Michael Stevenson. “Ignoring a leak can lead to further engine damage and costly repairs down the line.”
