A Guide to the Engine Valve Cover Gasket Set for the 2012-2018 BMW X5
Leaking oil and smelling something burning? Your X5's valve cover gasket is a likely culprit.
- A burning oil smell is the most common sign of a failing valve cover gasket on the X5.
- For a lasting repair, plan to replace the entire plastic valve cover, not just the gasket, due to warping and integrated PCV valve failures.
- Elring is a highly-regarded aftermarket brand that is often an OE supplier, making it a reliable choice.
- While a DIY replacement is possible, it is a time-consuming job with hard-to-reach bolts and brittle plastic parts.
Is Your BMW X5 Leaking Oil?
A leaking valve cover gasket is one of the most common oil-related repairs for the 2012-2018 BMW X5, affecting engines like the popular N55 inline-six. 🎬 Watch this video to identify common symptoms of a leak. The plastic valve covers used on these engines are known to warp or crack from constant heat cycles, which prevents a new gasket from sealing properly. Because of this, many mechanics recommend replacing the entire valve cover assembly along with the gasket, especially on vehicles with over 70,000 miles. The valve cover often has an integrated PCV (Positive Crankcase Ventilation) system, and when its internal diaphragm fails, it requires the replacement of the whole cover.
Gasket Only vs. Full Valve Cover Replacement
While just replacing the gasket is cheaper, it may not solve the leak if the original plastic cover is warped or has a failed PCV valve. For a lasting repair, especially on higher-mileage X5s, replacing the entire valve cover assembly is the recommended course of action.
Choosing the Right Aftermarket Gasket Set
When shopping for a new aftermarket valve cover gasket set, quality matters. A poor-quality gasket can fail prematurely, forcing you to do the job all over again. Here is a breakdown of the available brands:
- Elring: Often considered an Original Equipment (OE) supplier for many German brands, Elring is a solid choice for gaskets and seals. They are generally well-regarded for fit and quality.
- Victor Gaskets (Victor Reinz): Another well-known OE supplier. However, some users report fitment issues with certain Victor Reinz gaskets for BMWs, so it's a bit of a gamble compared to Elring.
- URO Parts: A popular aftermarket brand. Quality can sometimes be inconsistent, but they offer a more budget-friendly option. Some owners have had success, while others prefer to stick with OE-equivalent brands.
- Elwis: This is another aftermarket brand. While less commonly discussed in forums than the others, it provides a cost-effective alternative.
Pro Tip: Many experienced technicians recommend using a small amount of RTV silicone sealant at the sharp corners and seams of the cylinder head during installation to prevent leaks, even with a new gasket.

Frequently Asked Questions
Are there any recalls for the 2012-2018 BMW X5 valve cover gasket?
No, there are no specific recalls for the valve cover or its gasket. However, there is a recall for some 2012-2018 X5 models involving the water pump, where a leak could potentially cause a fire risk. This is unrelated to the valve cover gasket itself.
Is it difficult to replace the valve cover gasket on an X5 myself?
This is a moderately difficult DIY job that can take several hours. It requires patience and care, especially when dealing with brittle plastic parts and hard-to-reach bolts at the back of the engine. For engines like the N55, you also have to remove fuel lines, which adds complexity. If you are not an experienced DIY mechanic, it may be best to leave this job to a professional.
🎬 See a step-by-step DIY guide for the N55 engine replacement.Should I replace the whole valve cover or just the gasket?
For the 2012-2018 X5, it is highly recommended to replace the entire valve cover assembly, not just the gasket. The plastic cover can warp from heat, and the integrated PCV valve is a common failure point that can only be fixed by replacing the cover. A new gasket on a warped cover will not seal properly and will leak again.
What other parts should I replace at the same time?
When replacing the valve cover or gasket, it's a good idea to inspect the ignition coils and spark plugs for oil contamination and replace them if necessary. Also, the PCV breather hose that connects to the valve cover is known to become brittle and break during removal, so it's wise to have a new one on hand.
