Engine Valve Cover Replacement Guide for the 2011-2016 Dodge Durango
Address common oil leaks and burning smells by understanding when and why to replace your Durango's valve cover.
- A burning oil smell is the most common symptom of a failing valve cover on the Durango.
- On 3.6L V6 models, always verify the leak isn't coming from the oil filter housing before replacing the valve cover.
- It is highly recommended to replace the entire valve cover assembly, not just the gasket, because the original plastic covers are known to warp and crack.
- Oil leaking into the spark plug wells is a common result of this failure and can cause engine misfires.
Is Your Durango's Valve Cover Failing?
A leaking valve cover is a common issue on both the 3.6L Pentastar V6 and 5.7L HEMI V8 engines in the 2011-2016 Dodge Durango. The original covers are made of plastic which can crack or warp over time from constant engine heat cycles. When this happens, simply replacing the gasket won't solve the leak. The most obvious signs are a burning oil smell and visible oil on the side of the engine.
Check This First on 3.6L V6 Engines!
The 3.6L Pentastar engine is known for a leaking oil filter housing, which sits in the valley of the engine. 🎬 Watch: How to replace a leaking 3.6L oil filter housing Oil from this leak can run down the back of the engine and drip, making it look exactly like a valve cover leak. Always have a mechanic confirm the true source of the leak before you buy parts.
Symptoms of a Bad Valve Cover
If your valve cover is failing, you'll likely notice one or more of these signs:
- Burning Oil Smell: This is the most common symptom, caused by oil dripping onto the hot exhaust manifold. You may notice it most when you're stopped or when the heater is on.
- Visible Oil Leaks: You may see wet, oily grime building up on the sides of the engine, particularly on the passenger side. In worse cases, you'll see oil spots on your driveway.
- Oil in Spark Plug Wells: The valve cover gasket set includes seals for the spark plug tubes. When these fail, oil can fill the wells, leading to engine misfires, a rough idle, and a check engine light (codes P0300-P0306).
- Low Engine Oil: A steady leak will cause your oil level to drop over time, requiring you to top it off frequently.
Choosing the Right Aftermarket Valve Cover: Dorman vs. Mopar
When it's time for a replacement, you have a choice between OEM (Mopar) and aftermarket brands like Dorman.
- Mopar (OEM): This is the original part your Durango came with. It guarantees a perfect fit but is often the most expensive option. For this part, many owners stick with OEM to avoid potential issues with aftermarket quality.
- Dorman: Dorman is a popular aftermarket brand that offers a more affordable alternative. While many Dorman parts are reliable, some users have reported issues with their plastic valve covers, such as defects in the gasket groove or problems with the integrated PCV system causing oil consumption. However, for many common repairs, Dorman provides a cost-effective solution that performs well.
Pro Tip: Because the plastic can warp, it is highly recommended to replace the entire valve cover assembly, not just the gasket. 🎬 Watch: Step-by-step guide for Durango valve cover gasket replacement A new cover ensures a flat, clean sealing surface for a long-lasting repair.
| Part Type | Estimated Cost |
|---|---|
| New OEM (Mopar) | $250 - $500 |
| New Aftermarket (Dorman, etc.) | $192.23 - $439.47 |
| Shop Labor | $183 - $269 |
Frequently Asked Questions (FAQ)
Do I need to replace the whole cover or just the gasket?
For the 2011-2016 Durango, it is strongly recommended to replace the entire valve cover. The original plastic covers are prone to warping and cracking from heat. A new gasket on a warped cover will not seal properly and will likely leak again soon. A new cover assembly includes a new gasket and ensures a perfectly flat surface.
Which side is harder to replace on the Durango?
The passenger side is generally more difficult to replace on both the 3.6L V6 and 5.7L Hemi engines. This is because more wiring harnesses, brackets, and other components are routed over the cover, making access very tight. 🎬 See this walkthrough for replacing the difficult passenger side cover On the 3.6L V6, the upper intake manifold must be removed to access the valve covers, especially the rear bank.
Should I use RTV sealant with the new gasket?
Yes. A small dab of RTV sealant is required at the points where the engine timing cover meets the cylinder head. These are sharp corners where the gasket alone may not seal perfectly. This is a critical step to prevent leaks.
Are there any recalls for the valve cover?
No, there are no specific recalls from Dodge or the NHTSA for leaking valve covers on the 2011-2016 Durango. This issue is considered a normal wear-and-tear item. There was a TSB for oil pan leaks on some 2016 5.7L models, which could be confused with a valve cover leak.
