Solve engine rattle and timing issues in your classic Dodge van by choosing the right replacement timing set.

Is Your Dodge B250's Engine Running Rough?
A rattling noise from the front of the engine, rough idling, or a sudden loss of power could point 🎬 Watch: How to check your timing chain in 5 minutes to a worn-out engine timing set. In the 1981-1994 Dodge B250, particularly those with the popular 5.2L (318) and 5.9L (360) V8 engines, the original timing set is a known weak point. Understanding why it fails helps you choose the best new aftermarket part.
The Original OEM Problem: Nylon Teeth
Many original timing sets from this era used a camshaft gear with nylon-coated teeth. This design was intended to make the engine run quieter. However, after decades of heat and mileage, the nylon becomes brittle, cracks, and breaks off. These broken pieces can cause the timing chain to become loose and 'jump' a tooth, throwing off engine timing. They can also fall into the oil pan and clog the oil pump pickup screen, leading to oil starvation and catastrophic engine failure.
Choosing the Right Aftermarket Timing Set
Virtually all new aftermarket timing sets are an upgrade over the original design because they use all-metal gears. This eliminates the primary failure point. When shopping, you can group the available brands into two main tiers.
Tier 1: Standard & Heavy-Duty Replacements
These are excellent choices for a daily driver or work van with a stock engine. They offer reliability that meets or exceeds the original part's specifications. Brands like Cloyes and Melling are trusted names in this category, known for providing durable, all-metal components that solve the nylon gear problem for good. They are the go-to for a standard, dependable repair.
Tier 2: High-Performance & Double Roller Sets
For owners who use their B250 for heavy towing, have a modified engine, or simply want the most durable option available, a performance set is the best choice. Brands like Edelbrock and Melling Select Performance offer kits with double roller chains. A double roller chain is significantly stronger and more resistant to stretching than a standard 'silent' type chain. These kits often feature heat-treated, billet steel gears for maximum longevity.
While You're In There...
Replacing the timing set is labor-intensive. Since you'll have the front of the engine disassembled, it is highly recommended to replace the water pump, timing cover gasket, and the front crankshaft seal at the same time. This will save you from having to do the same job twice down the road.
