Engine Valve Cover Gasket Set for the 2007-2016 BMW 328i
Addressing the common N52 engine oil leaks starts with understanding the valve cover gasket.
- The plastic valve cover on the N52 engine is often the root cause of the leak due to warping or cracking, not just the gasket.
- For a lasting repair, it is highly recommended to replace the entire valve cover assembly, not just the gasket.
- While replacing the gasket, you should also replace the Valvetronic motor and eccentric shaft sensor seals.
- Brands like Elring and Victor Reinz are considered OE-quality, but check for kit completeness.
Is Your BMW 328i Leaking Oil? The Valve Cover Gasket is a Common Cause
If you own a 2007-2016 BMW 328i, you are likely familiar with its N52 engine. A frequent issue with this engine is an oil leak from the valve cover gasket. Over time, the constant heat from the engine causes the rubber gasket to become hard, brittle, and shrink. This prevents it from sealing properly, allowing oil to escape. 🎬 Watch: How to confirm your BMW is leaking oil right now. This is a very common repair for the N52 engine, often needed around 100,000 miles.
More Than Just a Gasket Problem
For 2007 and newer 328i models with the N52 engine, the valve cover itself is made of a composite plastic. After thousands of heat cycles, this plastic cover can warp or develop microcracks, which is often the true source of the leak. For this reason, many mechanics recommend replacing the entire valve cover assembly, not just the gasket, to ensure a long-lasting repair. Aftermarket valve cover kits typically include a new cover, the main gasket, spark plug tube seals, and sometimes new hardware.
Choosing the Right Aftermarket Gasket Set
When shopping for a replacement, you'll find several aftermarket brands. Quality can vary, so it's important to choose wisely to avoid having to do the job twice.
- Premium Brands (Often OEM Suppliers): Brands like Elring and Victor Reinz are often original equipment (OE) suppliers to BMW. This means their parts are made to the same specifications as the original. While generally high-quality, some users report fitment issues with Victor Reinz seals, while Elring is consistently well-regarded for this application.
- Quality Aftermarket Brands: Beck Arnley is known for sourcing parts from various manufacturers, often re-boxing OE-quality components. Elwis is another established aftermarket brand offering reliable gasket sets.
- Value-Oriented Brands: URO Parts offers a more budget-friendly option. While some owners have used them successfully, they have a mixed reputation in forums compared to premium brands. However, some URO kits come with multi-year warranties.
Pro Tip: When replacing the valve cover gasket, it's highly recommended to also replace the Valvetronic motor gasket and the eccentric shaft sensor seal at the same time, as these are prone to leaking and are accessible during the job. Many comprehensive aftermarket kits include these extra seals.

Frequently Asked Questions
Do I need to replace the whole valve cover or just the gasket?
Because the original plastic valve cover on the N52 engine can warp or crack, replacing the entire valve cover assembly is the recommended fix for a permanent solution. A warped cover will cause a new gasket to fail quickly. If you are on a tight budget, you can try just the gasket, but be aware it may not solve the leak if the cover itself is the problem.
Do I need to replace the valve cover bolts?
It depends on the year. Early N52 engines (pre-2007) with a magnesium valve cover used one-time-use aluminum bolts that must be replaced. However, the 2007-2016 328i models with the plastic valve cover have reusable bolts, so they do not need to be replaced.
Is this a good DIY job for a beginner?
This job is considered intermediate in difficulty. While it doesn't require highly specialized tools, it is time-consuming (around 3-4 hours) 🎬 Watch: A quick 6-minute overview of the gasket replacement process. and involves removing many components in a tight space.

No, there are no specific recalls for the valve cover gasket itself. There was a recall (NHTSA 22V119000) for the PCV valve heater, which is located near the valve cover, due to a fire risk from short-circuiting. However, this does not cover oil leaks from the main gasket.
