Land Rover Engine Oil Filler Cap Gasket - Genuine Land Rover LR073781

Product Information

An engine oil filler cap gasket is a small, often rubber or silicone ring that sits between the engine oil filler cap and the valve cover. Its purpose is to form a seal that prevents engine oil from leaking out and contaminants like dirt and debris from entering the engine. Over time, exposure to high temperatures and engine oil can cause the gasket to wear out, become brittle, degrade, leading to leaks or other issues.

• Oil Leaks around the Filler Cap: One of the most common signs of a worn gasket is visible oil around the filler cap area. If the gasket can’t form a proper seal, oil may seep out, especially when the engine is running and oil pressure is higher
• Dirt or Debris near the Filler Cap: A compromised gasket may allow dust and dirt to enter the engine compartment, leading to contamination of the oil and potential damage to engine components
• Loose Filler Cap: If the gasket is overly worn or damaged, the cap may not fit securely, leading to a looser, wobbly fit that can exacerbate leaks and make it easier for contaminants to enter

About Genuine Land Rover

The same parts Land Rover used to build your vehicle are sold as replacement parts under the “Genuine Land Rover” brand. These are manufactured under Land Rover’s direction, guaranteeing top quality. As you’d expect, they also carry a premium price and are sold exclusively through the Land Rover dealership network.

Genuine Land Rover parts trace their origins back to the earliest days of the brand in 1948, when Rover engineers built the first Series I using robust, serviceable components designed for durability in harsh environments. Over the decades, Land Rover established partnerships with leading European suppliers to ensure consistent quality and performance. This tradition continues today, with Genuine Land Rover parts representing the official replacement components engineered to the same specifications as those used on the production line.

What many owners don’t realize is that Land Rover doesn’t manufacture most of these parts themselves. Instead, they design the components, contract trusted suppliers to produce them, and then verify the quality. Many of these suppliers have partnered with Land Rover for decades. In the industry, they’re known as OEMs (Original Equipment Manufacturers)—brands you probably recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. It’s not unusual to open a Genuine Land Rover box and find one of these brands inside—just re-badged with a Land Rover logo.

On our site, look for OE tags on product pages to quickly spot parts that come straight from the original manufacturers. Choosing these can save you a significant amount compared to buying them in Genuine packaging. For more details on how to identify OE and OEM parts, check out our OE Academy.
