Chevy Cruze Oil Leak on Passenger Side – What’s Causing It

If you own a Chevy Cruze, you may have experienced an oil leak on the passenger side of your vehicle. This can be a frustrating issue to deal with, as it can lead to a loss of oil and potential engine damage if not addressed promptly. In this article, we will explore the common causes of oil leaks on the passenger side of a Chevy Cruze and provide solutions to fix the issue.

One of the leading causes of an oil leak on the passenger side of a Chevy Cruze is a faulty oil pan gasket. The gasket can become worn or damaged over time, leading to oil seeping out and causing a leak.

In this article we’ll discuss the most common causes and what you can do to stop the leak!

Causes of Oil Leaks on Passenger Side of Chevy Cruze

If you have noticed an oil leak on the passenger side of your Chevy Cruze, there are several possible causes that you should be aware of.

Here are two of the most common culprits:

Faulty Oil Pan Gasket

One of the most common reasons for an oil leak on the passenger side of a Chevy Cruze is a faulty oil pan gasket. This gasket is responsible for sealing the oil pan to the bottom of the engine block, and if it becomes damaged or worn out, oil can leak out of the pan and onto the ground.

Over time, the gasket can become brittle and crack, allowing oil to seep through the gap. If you suspect that your oil pan gasket is the cause of your oil leak, you should have it replaced as soon as possible to prevent further damage to your engine.

Damaged Oil Filter

Another possible cause of an oil leak on the passenger side of your Chevy Cruze is a damaged oil filter. The oil filter is responsible for removing contaminants from the oil as it circulates through the engine, and if it becomes damaged or worn out, it can allow oil to leak out of the filter housing.

Repair Costs

If you need to replace a fault oil pan gasket, you can expect to pay around $175 for the part and fix it yourself. If you need a mechanic you can expect to closer to $400.

If you need to replace a damaged oil filter this is a much cheaper, but unfortunately, less common fix, particularly for a leak on the passenger side.

In the event it is due to a damaged oil filter you can pick up some new filters for around $50 or take it to a mechanic and get it replaced for around $100 including labor.

Preventive Measures and Maintenance

To avoid additional leaks on the passenger side of your Chevy Cruze, it is important to perform regular maintenance and take preventive measures. Here are some tips to keep your engine in good condition:

  • Check the oil level regularly: Make sure you check the oil level regularly, especially if you notice any changes in your car’s performance. Low oil level can cause engine damage and oil leaks.
  • Use high-quality oil and filters: Always use high-quality oil and filters that meet the manufacturer’s specifications. Cheap oil and filters can cause leaks and other engine problems.
  • Replace the oil pan gasket: The oil pan gasket is a common cause of oil leaks on the passenger side of the Chevy Cruze. If you notice any signs of a leak, such as oil spots on the ground or low oil level, it may be time to replace the gasket.
  • Inspect the oil cooler lines: The oil cooler lines can also cause leaks if they are damaged or worn out. Inspect them regularly and replace them if necessary.
  • Check the valve cover gasket: The valve cover gasket can also cause leaks if it is damaged or worn out. Inspect it regularly and replace it if necessary.
  • Keep the engine clean: A clean engine is less likely to develop leaks. Use a degreaser and a pressure washer to clean the engine regularly.

By following these preventive measures and performing regular maintenance, you can reduce the risk of oil leaks.
