Stop that burning oil smell and keep your engine clean with the right valve cover gasket set for your Durango.
- The most common symptom of a bad valve cover gasket is a burning oil smell from oil hitting the hot exhaust.
- Confirm the leak isn't from another common source, like the oil filter adapter housing, before starting repairs.
- High-quality aftermarket brands like Fel-Pro or Victor Reinz offer excellent value and reliability for this repair.
- Always buy a complete set that includes spark plug tube seals and bolt grommets for a lasting repair.
Is Your Durango Leaking Oil? It Might Be The Valve Cover Gaskets
An oil leak from the valve cover gasket is one of the most common issues on any engine, including the 3.7L V6, 4.7L V8, and 5.7L HEMI V8 found in the 2004-2010 Dodge Durango. The gasket lives in a hot environment and eventually wears out. When it fails, oil seeps out, making a mess and causing other problems. While it's not a critical failure that will leave you stranded, it's a repair you shouldn't ignore.
Symptoms of a Failing Valve Cover Gasket
If your valve cover gaskets are failing, you'll likely notice one or more of these signs:
🎬 Watch: Common symptoms of a leaking valve cover gasket- Burning Oil Smell: This is the most common symptom. Leaking oil drips onto the hot exhaust manifold, where it burns off and creates a distinct, unpleasant smell that you may notice inside and outside the vehicle.
- Visible Oil and Grime: You'll see wet, oily patches on the valve covers themselves. This oil attracts dirt and grime, creating a thick, greasy buildup on the top of your engine.
- Oil on the Ground: A small but consistent drip can leave oil spots on your driveway or garage floor.
- Low Engine Oil Level: A leaking gasket can cause a slow but steady loss of engine oil, requiring you to top it off between oil changes.
- Rough Running or Misfires: On many Durango engines, the gasket set also includes seals for the spark plug tubes. If these seals fail, oil can fill up the spark plug wells, causing a misfire and a check engine light.
Correct Diagnosis is Key
Other parts can leak oil and be mistaken for a valve cover gasket. On the 2004-2010 Durango, the oil filter adapter housing or engine oil cooler, located in the 'V' of the engine, can also leak. This oil often runs down the back of the engine and transmission, looking very similar to a valve cover or rear main seal leak. A mechanic may need to clean the engine and use a special UV dye to pinpoint the exact source of the leak.
Choosing the Right Aftermarket Gasket Set
You don't necessarily need to buy an expensive OEM gasket from the dealer. Many aftermarket brands offer excellent quality, often for a much lower price. For a part like this, a quality aftermarket option is a smart choice for most owners.
- Tier 1 (Premium Aftermarket): Brands like Fel-Pro, Victor Reinz, and Mahle are well-regarded in the repair industry. Fel-Pro is known for designing gaskets specifically for the repair environment, often with features to help seal imperfect surfaces. Victor Reinz and Mahle are often original equipment suppliers to many car manufacturers. You can trust these brands for a reliable, long-lasting seal.
- Tier 2 (Standard Aftermarket): Brands like Apex, Crown Automotive, and others offer a good balance of price and quality. Crown is a popular choice for Dodge-specific parts. These are a solid option for a budget-conscious repair.
Pro Tip: Buy a Complete Kit
Always purchase a complete valve cover gasket *set*. A good set will include the main valve cover gaskets, spark plug tube seals, and new grommets for the mounting bolts. Replacing all these components at the same time is critical for a leak-free repair.
Cost to Replace Dodge Durango Valve Cover Gaskets

Frequently Asked Questions
Are there any recalls for Durango valve cover gaskets?
No, there are no specific recalls or widespread technical service bulletins (TSBs) for leaking valve cover gaskets on the 2004-2010 Dodge Durango. However, one owner filed a complaint with the NHTSA about a leaking windshield cowl allowing water to drip onto the engine, which could lead to other issues. It's always a good idea to keep the cowl area clean of debris.
Is this a difficult DIY job?
For a moderately experienced DIY mechanic, this is a manageable job. The driver's side is usually straightforward. The passenger side can be more challenging due to components like the A/C lines, brake booster, and wiring harnesses being in the way. You'll need a good socket set, torque wrench, and patience. If you are not comfortable working in tight spaces, it may be best to leave this to a professional.

Yes, in most cases. You will typically need to apply a small dab of oil-resistant RTV sealant at the corners or sharp bends where the engine block, cylinder head, and timing cover meet. This helps seal the joints between different engine components. The instructions with your new gasket set should specify the exact locations.
Should I replace my spark plugs at the same time?
This is an excellent time to inspect and likely replace your spark plugs. You will already be removing the ignition coils and accessing the spark plug tubes. If you find oil in the spark plug wells, it's essential to clean it out thoroughly before installing new plugs to prevent misfires.
