Timing Chain Maintenance Tip

The engine crankshaft turns a timing chain or timing belt to spin the camshaft. Engines with worn out timing belts usually run fine until the belt breaks and the engine stops. High mileage timing chains often stretch long before they break and the engine will continue to run. A stretched timing chain might cause backfiring, loss of power, exhaust smoke, rough idle / acceleration, and other problems resulting from incorrect valve and ignition timing.

These symptoms can be hard to diagnose individually. Is the PCV valve loose? Is the catalytic converter clogged? Is a spark plug wire bad? Is the choke stuck? Did a sensor fail? To diagnose a stretched timing chain, consider the vehicle's repair history (the spark plug wires were replaced last month). Watch for ignition, exhaust, and fuel symptoms occurring all at once. Listen for noise from the timing chain cover as the loose chain rattles around on the chain sprocket, and consider the vehicle's mileage.

Replace the timing chain, sprockets, and other timing components as a set to avoid prematurely stretching a new chain with an old gear. RockAuto has all of the parts you need for this type of repair from several premium manufacturers. You will find these parts and much more in the ENGINE category of our catalog.

Hello RockAuto,

3 years ago I was visiting friends in Appleton Wisconsin where I found a 1974 Dodge Charger. My son had always dreamt of having one, so I paid $2000 for the car, and had it shipped home to Belgium to begin the restoration.

Today, the Mopar is running very smooth and is almost done. I just need to put on the hood and doors.

Finding the parts I need for the Charger here in Europe is not easy and very expensive! But, thanks to RockAuto's good service and correct shipments, I could restore my first Mopar.

Thank you and keep up the good work!

Clark in Antwerp Belgium
