Exhaust Manifold Gasket Set Guide for 2017-2024 Dodge Durango
Hearing a ticking noise from your Durango's engine bay? Your exhaust manifold gaskets may be the culprit.
- The most common failure is not the gasket but broken manifold bolts, especially on 5.7L HEMI engines.
- A ticking noise on a cold start that fades when warm is the classic symptom of an exhaust manifold leak.
- Always replace the manifold bolts with a new, high-quality set; do not reuse the old ones.
- Budget for potential broken bolt extraction, as this can significantly increase repair costs and time.
Is Your Durango's Exhaust Manifold Gasket Failing?
A leaking exhaust manifold gasket is a common problem, especially on the 5.7L HEMI V8 engine. The most frequent cause is not the gasket itself failing, but the factory exhaust manifold bolts breaking under constant, intense heat cycles. The cast-iron manifolds and aluminum cylinder heads expand and contract at different rates, putting immense stress on the bolts until they snap. This creates a small gap, allowing the gasket to blow out and leak.
Known Issues for 2017-2024 Dodge Durango
Technical Service Bulletin (TSB) for 5.7L HEMI
Dodge has issued Technical Service Bulletin (TSB) 09-019-23 for 2019-2022 Dodge Durangos with the 5.7L V8 engine. This TSB addresses a customer complaint of a "ticking noise from the exhaust manifold location(s) when cold." 🎬 Watch: Hear what a HEMI exhaust leak actually sounds like The official repair involves replacing the manifolds with an updated kit, acknowledging the issue with the original parts.
Choosing the Right Aftermarket Gasket Set
When replacing your exhaust manifold gaskets, the quality of the new parts matters. Since broken bolts are the root cause, it's highly recommended to replace all manifold bolts at the same time. For the gaskets, a Multi-Layer Steel (MLS) design is the preferred choice for durability.
Aftermarket Brand Tiers
- Premium Choice (Best): Brands like Cometic Gasket specialize in high-performance MLS gaskets that are excellent for handling the high heat and pressure of the HEMI engine. They are often a top choice for engine builders.
- Quality Aftermarket (Better): Fel-Pro is a highly respected brand known for engineering gaskets specifically for repair scenarios where sealing surfaces may not be perfectly flat. Their MLS options are a reliable upgrade over standard composite gaskets. Victor Reinz is another OE-quality supplier offering durable gasket designs.
- Standard Replacement (Good): Brands like BBK Performance offer standard replacement gaskets that will get the job done and meet or exceed original specifications.
Pro Tip: Regardless of the gasket brand you choose, invest in high-quality replacement exhaust manifold bolts or studs. Many mechanics working on HEMI engines upgrade to stronger hardware from companies like ARP to prevent the bolts from breaking again. Also, ensure your mechanic uses an anti-seize compound on the new bolts to make any future repairs easier.

Frequently Asked Questions (FAQ)
Why does the ticking noise go away after the engine warms up?
When the engine is cold, the gap from the broken bolt and failed gasket is open, allowing exhaust to escape and create a ticking sound. As the engine heats up, the metal exhaust manifold expands, often closing the gap just enough to temporarily seal the leak and quiet the noise.
Do I have to replace the exhaust manifold too?
Not always, but you should inspect it carefully. The same heat cycles that break the bolts can cause the manifold itself to warp or crack. If the manifold is warped, a new gasket will not seal properly and will fail again quickly. A professional shop will check the manifold with a straightedge to ensure it's flat.
🎬 Watch: How to remove those stubborn broken manifold boltsCan I reuse the old exhaust manifold bolts?
No. The original bolts are the weak point in the system and are prone to stretching and breaking. It is critical to use a new set of high-quality bolts or studs when replacing the gaskets to ensure a long-lasting repair.
Should I replace gaskets on both sides at the same time?
It is highly recommended. The conditions that caused one side to fail (age, heat cycles) are identical on the other side. If one gasket has failed, the other is likely not far behind. Replacing both at once saves you from having to do the same labor-intensive job again in the near future.
