Jeep Commander Engine Valve Cover and Gasket Guide (2006-2010)
If you smell burning oil, it's likely time to inspect your Jeep Commander's valve covers and gaskets.
- A burning oil smell is the number one sign of a leaking valve cover on a Jeep Commander.
- Replacing the entire valve cover is often better than just the gasket, as the original plastic covers can warp.
- Labor costs vary greatly by engine; the 5.7L HEMI is the most difficult and expensive to service.
- Always use a complete kit that includes new gaskets, spark plug tube seals, and bolt grommets.
Is Your Commander's Valve Cover Leaking?
A leaking valve cover is one of the most common oil leaks on the 2006-2010 Jeep Commander. Because the covers sit high on the engine, the signs are usually easy to spot. Over time, the constant heat from the engine causes the original plastic covers to warp and the rubber gaskets to become hard and brittle, leading to cracks and leaks.
Key Symptoms of a Failing Valve Cover or Gasket:
🎬 Watch: 5 telltale signs of a bad valve cover gasket- Burning Oil Smell: This is the most common sign. Oil drips from the leaking cover or gasket onto the hot exhaust manifold below, creating a distinct burning smell you might notice inside or outside your Jeep.
- Visible Oil and Grime: You'll see wet, oily areas around the edges of the valve covers on top of the engine. This oil attracts dirt, forming a thick, grimy buildup.
- Oil in Spark Plug Wells: If the spark plug tube seals fail (which are part of the valve cover gasket set), oil can fill the spark plug tubes. This is especially common on the V8 engines. It can lead to a rough running engine, misfires, and a check engine light.
- Low Engine Oil: A significant leak will cause your oil level to drop between oil changes, requiring you to top it off frequently.
Why Replace the Whole Cover, Not Just the Gasket?
While you can replace just the gasket, it's often a short-term fix. The original plastic valve covers on these Jeeps are prone to warping and developing hairline cracks from years of heat cycles. A warped cover won't seal properly even with a new gasket, meaning your leak will likely return. Replacing the entire valve cover assembly ensures a flat, new sealing surface and often includes improved gaskets and an updated PCV system design, providing a more permanent solution.
Choosing the Right Aftermarket Valve Cover
When shopping for a replacement, you'll find OEM Mopar parts and several aftermarket options. For the 2006-2010 Commander, a quality aftermarket part can be a smart choice.
Brand Tiers for Jeep Commander Valve Covers
- Mopar (OEM): This is the original factory part. It guarantees a perfect fit but comes at the highest cost. Some owners who have had issues with aftermarket gaskets leaking have switched to Mopar for a better seal.
- Dorman: Dorman is a well-known aftermarket brand that often redesigns parts to fix common factory flaws. Their valve covers for Jeep may use improved materials or have better internal baffling for the PCV system. They are generally considered a reliable and cost-effective alternative to OEM. However, like any aftermarket part, defective units can occasionally be found, so purchase from a reputable seller.
- URO Parts / Other Budget Brands: These are typically the most affordable options. While they can provide a functional replacement, quality can be inconsistent. For a critical part like a valve cover, where the labor to replace it is significant, spending a little more on a higher-quality brand like Dorman or Mopar is often recommended to avoid doing the job twice.
Pro Tip: Always buy a complete kit. A good aftermarket valve cover should come with a new gasket, spark plug tube seals, and bolt grommets already installed. This saves time and ensures all sealing components are fresh.

Frequently Asked Questions
Are there any recalls for the Jeep Commander valve cover?
No, there are no specific recalls or Technical Service Bulletins (TSBs) from Jeep or the NHTSA for valve cover or gasket failures on the 2006-2010 Jeep Commander. This issue is considered a standard maintenance and repair item that occurs due to age and heat exposure.
Is this a DIY job?
For an experienced DIY mechanic, yes. The difficulty is moderate. The 3.7L V6 is the most straightforward. 🎬 Watch: Step-by-step guide for the 3.7L passenger side gasket The V8 models, particularly the 5.7L HEMI, are more challenging due to tight spaces around the back of the engine and components that need to be moved. You will need a good set of sockets, extensions, and a torque wrench. If you're not comfortable, it's best to leave this to a professional.
Do I need to replace both valve covers at the same time on my V8?
It's highly recommended. The valve covers and gaskets on both sides of the engine have been exposed to the same amount of heat and time. If one side is leaking, the other is likely not far behind. Replacing both at once saves you from having to do the job again in the near future.
What is the PCV valve and should I replace it too?
The PCV (Positive Crankcase Ventilation) valve is a crucial part of the emissions system that is often located in the valve cover. A clogged or failing PCV valve can cause pressure to build up in the engine, forcing oil out through gaskets and seals. It's inexpensive and easy to replace while you have everything apart, making it a smart and preventative maintenance step.
