The most common Range Rover oil leak problems are caused by faulty gaskets or seals, worn out engine components, cracked engine block and general wear and tear as the Range Rover accumulates more miles.

Every Range Rover model and year is notorious for oil leaks. It’s a big SUV with a powerful engine that needs to be lubricated.

Read on for more common causes for your Range Rover’s oil leak, symptoms, and how you can fix it.

What models are affected?

Signs and symptoms

The most common signs and symptoms of a Range Rover oil leak are fairly obvious.

Keep an eye out for the following indicators:

• Puddles of oil under your Range Rover: Usually under the driver’s side. This is perhaps the most obvious sign of an oil leak. If you notice dark and slippery patches forming under your vehicle, it’s time to investigate further.
• The smell of burnt oil: If a faint scent of burnt oil permeates the air when you’re near your Range Rover, it may indicate an oil leak. The leaking oil can come into contact with hot engine components, causing that distinct odor.
• Low oil level: Regularly check your oil level using the dipstick. If you find yourself having to top up the oil more frequently than usual, it could be oil leak problems.

Common causes

Now that we have a general idea of what to look for, let’s explore some common causes of Range Rover oil leaks:

1. Faulty gaskets or seals: Over time, gaskets and seals can degrade, resulting in oil leakage. The most common culprits are the valve cover gasket, oil pan gasket, and crankshaft seal.
2. Worn-out engine components: As your Range Rover accumulates mileage, certain engine parts can wear out, leading to oil leaks. The most vulnerable components include the oil filter housing, oil cooler seals, and valve stems.
3. Loose or damaged drain plug: The drain plug plays a crucial role in sealing the oil pan. If it becomes loose or damaged, it can cause oil to seep out.
4. Cracked engine block: While rare, a cracked engine block can cause substantial oil leaks. This is a more severe issue that may require professional intervention.

Can it be fixed without a mechanic?

It depends on your level of mechanical expertise and the specific issue at hand.

Some minor leaks, such as a loose drain plug or a worn oil filter housing seal, can be addressed by enthusiasts with adequate tools and knowledge.

However, for more complex problems like a cracked engine block, seeking professional help is highly recommended to ensure a thorough and lasting fix.
