A Guide to the Engine Valve Cover Gasket Set for the 2007-2020 Mini Cooper
Stop the common oil leaks and burning smells by choosing the right valve cover gasket for your Mini.
- For 2007-2013 (R56) models, plan to replace the entire valve cover, not just the gasket, to address potential warping and the integrated PCV valve.
- Choose high-quality aftermarket brands like Elring or Victor Reinz that are known OEM suppliers for the best results.
- When replacing the gasket, always check the spark plug tubes for oil and inspect the ignition coils for damage.
- The replacement is a manageable DIY job for R56 models but is much more complex and best left to a professional for F56 models.
Is Your Mini Cooper Leaking Oil?
A leaking valve cover gasket is one of the most common issues for 2007-2020 Mini Cooper owners, especially for the second-generation (R56) models from 2007-2013. These leaks start as small drips but can quickly make a mess of your engine, cause a burning oil smell, and lead to more serious problems if ignored. This guide will help you understand the symptoms, choose the right aftermarket parts, and know what to expect from the repair.
Symptoms of a Failing Valve Cover Gasket
The signs of a bad valve cover gasket are usually easy to spot:
- Visible Oil Leaks: You may see dark, damp areas on the top of the engine or streaks of oil running down the side. The leak is often most noticeable at the corners of the valve cover.
- Burning Oil Smell: As oil drips from the gasket, it often lands on the hot exhaust manifold, creating a distinct and unpleasant burning smell inside and outside the car.
- Oil in Spark Plug Wells: When the inner spark plug tube seals fail, oil can pool around the spark plugs. This can ruin the ignition coils and cause the engine to misfire, leading to a rough idle and a flashing check engine light.
- Low Engine Oil Light: A significant leak will cause your engine to lose oil over time, eventually triggering the low oil warning light. 🎬 Watch this video to diagnose common Mini Cooper oil leaks.
Generation-Specific Issues to Know
For 2007-2013 (R56) Models: The plastic valve cover on these models is known to warp or crack over time due to heat. More importantly, the Positive Crankcase Ventilation (PCV) valve is built directly into the cover. When the PCV system fails, it can cause high oil consumption and force leaks. For this reason, 🎬 See how a bad PCV valve causes these engine symptoms. mechanics often recommend replacing the entire valve cover assembly, not just the gasket.
For 2014-2020 (F56) Models: While gaskets still fail, the repair is much more complex. Replacing the gasket on these engines requires removing the high-pressure fuel rail and fuel injectors, which demands special tools and procedures. This is generally not a job for a beginner DIYer.
Choosing the Right Aftermarket Gasket Brand
Not all aftermarket gaskets are created equal. For a part this prone to failure on a Mini, quality matters. Here’s a breakdown of available brands.
Tier 1: OEM-Quality Aftermarket
These brands are often the original equipment manufacturers for BMW/Mini, offering the best fit and longevity.
- Elring: Widely regarded as an OEM supplier, Elring gaskets are a top choice for European vehicles, ensuring a precise fit.
- Victor Reinz: Another trusted OEM supplier known for high-quality sealing technology designed to withstand high engine temperatures.
Tier 2: Reputable Aftermarket
These brands have a strong reputation for quality and are a solid alternative to OEM parts.
- Beck Arnley: This brand is known for sourcing parts from various manufacturers, often including OEM suppliers. Their parts are generally considered reliable.
Tier 3: Budget-Friendly Options
These brands offer a lower price point, but quality and longevity can be inconsistent.
- URO Parts: This brand has a mixed reputation. While some users have had success, many professional mechanics and forum users warn against URO gaskets and valve covers due to issues with fitment and premature failure of integrated components like the PCV valve. Consider this a higher-risk option.
- Apex / Elwis: These brands are less common in forum discussions, making it harder to judge their long-term quality for this specific application.

Frequently Asked Questions
Can I just replace the gasket or do I need the whole valve cover?
For 2007-2013 models, it is highly recommended to replace the entire valve cover. The original plastic can warp, and the integrated PCV valve is a common failure point that a new gasket alone won't fix. For 2014+ models, replacing just the gasket is standard practice.
Is this a good DIY project?
For a 2007-2013 (R56) Mini, yes. The job takes 1-2 hours with basic tools and is a great way to save on labor costs. 🎬 Follow this step-by-step R56 valve cover replacement walkthrough. For a 2014+ (F56) Mini, it is not recommended for beginners due to the need to remove the fuel system.
Do I need to use sealant on the new gasket?
Yes, a small dab of RTV silicone sealant is required in the corners where the engine's timing cover meets the cylinder head. This is a critical step to prevent leaks from these small seams.
What else should I check or replace at the same time?
While the valve cover is off, inspect the ignition coils for oil contamination. If they are swollen or oily, they should be replaced to prevent misfires. It's also a good time to replace the spark plugs if they are due. Finally, check the serpentine belt for cracks or wear, as oil leaks can cause it to degrade prematurely.
