Jeep Commander Engine Valve Cover Gasket Replacement Guide (2006-2010)
Stop that burning oil smell and fix common leaks by choosing the right engine valve cover gasket set for your Commander.
- A burning oil smell is the most common symptom of a failing valve cover gasket on a Jeep Commander.
- Always purchase a complete gasket 'set' that includes spark plug tube seals and bolt grommets for a leak-free repair.
- Fel-Pro is a highly recommended aftermarket brand known for quality and durability.
- Expect higher labor costs for V8 models (4.7L and 5.7L HEMI) compared to the 3.7L V6 due to more difficult access.
Is Your Jeep Commander Leaking Oil? Common Symptoms
A failing valve cover gasket is one of the most common oil leaks on any vehicle, including the 2006-2010 Jeep Commander. Because the gasket sits high on the engine, the signs are usually easy to spot.
- Burning Oil Smell: This is the most frequent complaint. Oil drips from the leaking gasket onto the hot exhaust manifolds below, burning off and creating a distinct, unpleasant smell that you may notice inside and outside the vehicle.
- Visible Oil and Grime: You will see wet, oily patches high on the engine, around the edges of the metal or plastic valve covers. This oil attracts dirt and dust, creating a thick, grimy buildup.
- Oil in Spark Plug Wells: For the 4.7L and 5.7L V8 engines, failing spark plug tube seals (part of the gasket set) allow oil to fill the tubes. This can cause the engine to misfire, run rough, and may trigger the Check Engine Light.
- Low Engine Oil Level: A significant leak will cause a noticeable drop in your engine oil level between changes, forcing you to top it off regularly.
Fire Hazard Warning
While you can drive with a minor leak, it's not recommended for long. Leaking oil can drip onto extremely hot exhaust components, creating a risk of an engine fire. Address leaks promptly.
Choosing the Right Aftermarket Gasket Set
You don't need to buy an expensive OEM Mopar gasket for a quality repair. The aftermarket offers excellent options that often meet or exceed original specifications. When shopping, always choose a complete "set" that includes the main gaskets, spark plug tube seals (for V8s), and bolt grommets.
Premium Aftermarket Brands: Fel-Pro, Mahle
Brands like Fel-Pro are highly regarded by professional mechanics and DIYers for their quality and design. Fel-Pro's PermaDryPlus gaskets often feature improvements over the original design, such as a rigid carrier to prevent leaks from high vacuum or heat and torque limiters to prevent over-tightening. Many consider Fel-Pro the leading aftermarket gasket brand. Mahle is another top-tier brand, often supplying parts directly to vehicle manufacturers.
OEM-Equivalent Brands: Victor Reinz, Crown Automotive
Victor Reinz and Elring are major OEM suppliers, primarily for European vehicles, but offer a wide range of quality gaskets for domestic models as well. Crown Automotive specializes in Jeep replacement parts and provides a reliable, direct-fit alternative to the original Mopar parts.
Budget-Friendly Brands: Apex
Brands like Apex offer a more affordable solution. While they can provide a good seal, they may not have the advanced features or longevity of premium brands. For a vehicle you depend on daily, investing a few extra dollars in a premium gasket set is often worth it for peace of mind.
Replacement Cost for 2006-2010 Jeep Commander
The cost to replace valve cover gaskets varies based on your engine. The 3.7L V6 is less complex than the 4.7L or 5.7L HEMI V8s, which require more labor.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Gasket Set | $18 - $108 |
| Shop Labor | $170 - $450+ |
| Total Professional Replacement | $210 - $800 |
Cost estimates are based on industry data and forum reports. Labor costs are higher for V8 models due to tighter access and more complex intake manifolds.
Pro Tip: Prepare the Surface
The secret to a long-lasting repair is preparation. Both the cylinder head and the valve cover surfaces must be perfectly clean and free of old gasket material and oil residue before installing the new gasket. Use a plastic scraper and brake cleaner to avoid scratching the metal surfaces.
Frequently Asked Questions (FAQ)
Do I need to use RTV sealant with the new gasket?
Yes, but only in specific locations. A small dab of oil-resistant RTV sealant is typically required where the engine timing cover meets the cylinder head, as these junctions can be a source of leaks. Do not apply sealant around the entire gasket, as this can cause it to slip out of place and leak.
Is it necessary to replace the spark plug tube seals and bolt grommets?
Absolutely. These seals are exposed to the same heat and oil as the main gasket and fail at the same rate. A leak from an old spark plug tube seal will fill the well with oil, causing misfires, while a leak from a bolt grommet will seep oil from the top of the valve cover. Always buy a complete kit that includes all these components.
Is this a difficult job to do at home (DIY)?
For a DIYer with moderate experience, this is a manageable job. The 3.7L V6 is more straightforward than the V8s. The passenger side on all engines is tighter and requires more patience to access the rear bolts. You will need a good socket set, extensions, and torque wrench. Watching a vehicle-specific replacement video online can be very helpful.
Are there any recalls for Jeep Commander valve cover gaskets?
No, there are no specific recalls or Technical Service Bulletins (TSBs) from Jeep or NHTSA for valve cover gasket failures on the 2006-2010 Jeep Commander. This is considered a normal wear-and-tear maintenance item that fails due to age and heat cycles.
