Dodge Aspen Engine Timing Set: A Complete Guide for 1976-1980
Understanding the heart of your Aspen's engine and how to choose the right replacement timing set.
- For V8 engines, upgrading from the original nylon-toothed cam gear to an all-metal aftermarket set is essential for reliability.
- Symptoms of failure include engine rattle, loss of power, and rough idling.
- Brands like Melling, Cloyes, and Edelbrock are well-regarded in the Mopar community for timing components.
- While doing the job, it's smart to also replace the timing cover gasket and front crankshaft seal.
Is Your Aspen's Timing Chain Failing?
An engine timing set is a wear item. After decades of service, the original chain in your Aspen has likely stretched, and the gear teeth have worn down. For V8 models, a common issue is the original camshaft gear, which often had nylon-coated teeth to reduce noise. Over time, this nylon becomes brittle, breaks off, and can fall into the oil pan, potentially clogging the oil pump pickup screen and starving the engine of oil. This makes replacing a worn timing set a critical repair.
Symptoms of a Worn Timing Set
🎬 Watch this guide to identify common signs of timing chain failure.- Rattling Noise: A loose, stretched chain can slap against the timing cover, creating a distinct rattling sound, especially at idle or when the engine is first started.
- Poor Engine Performance: A stretched chain can retard ignition timing, leading to a noticeable loss of power, sluggish acceleration, and poor fuel economy.
- Engine Misfires: When timing is off, the engine may run rough, misfire, or have an unstable idle.
- Metal Shavings in Oil: During an oil change, finding small metal or plastic pieces in the drained oil is a major red flag that the timing gears are disintegrating.
Choosing the Right Aftermarket Timing Set
For a vintage vehicle like the Aspen, aftermarket timing sets are not only the most available option but often a significant upgrade over the original factory parts. The key is to choose the right type for your needs.
Brand & Quality Tiers
| Tier | Brands | Best For | Notes |
|---|---|---|---|
| Standard Replacement | INA, Melling (Standard), Cloyes (Standard) | Daily drivers, stock restorations | These offer reliable, quiet operation similar to OEM. Many will feature an all-metal construction, which is a durability upgrade over the original nylon-toothed gears on V8s. |
| Heavy-Duty / Performance | Cloyes (Double Roller), Melling Select Performance, Edelbrock | Performance builds, heavy-duty use, maximum durability | These sets often use a "double roller" chain, which is stronger and more precise than the stock "link-style" chain. They are made from billet steel or high-strength iron for longevity. While extremely durable, they can produce slightly more noise than a standard set. |
Pro Tip: Upgrade to All-Metal Gears
If you have a 318 or 360 V8, regardless of which brand you choose, ensure the replacement set has an all-metal (cast iron or steel) camshaft sprocket.

Frequently Asked Questions
What is the difference between a timing chain and a timing belt?
Your Dodge Aspen uses a timing chain, which is a metal chain lubricated by engine oil. A timing belt is a rubber composite belt that runs dry. Chains are generally designed to last longer but can stretch over time, while belts require replacement at scheduled intervals.
Should I get a standard or double roller timing set?
For a stock engine used for normal driving, a quality standard all-metal set from a brand like Melling or INA is perfectly adequate and cost-effective. If you are building the engine for more power, or simply want the most durable option, a double roller set from Cloyes, Melling Select, or Edelbrock is a worthwhile investment.
What else should I replace along with the timing set?
Since you have to remove the timing cover to access the chain, it is the perfect time to replace the timing cover gasket and the front crankshaft seal. It is also a good idea to inspect the water pump and replace it if it shows any signs of wear or leakage, as it must be removed for the job.
Were there any recalls on the Dodge Aspen for timing chains?
No, there were no specific recalls issued by the NHTSA for the engine timing set on the 1976-1980 Dodge Aspen. While the Aspen and its twin, the Plymouth Volaré, were subject to numerous recalls for other issues like suspension, brakes, and premature rust, the timing components were not part of a specific recall campaign.
