What causes a timing chain to go bad?

The most common cause of timing chain stretch is lack of maintenance and regular oil changes. Worn out oil can no longer lubricate the chain and will cause the rollers and links to wear against each other. … As the timing chain wears, this can change the timing of the camshaft and crankshaft.

How do you know if your engine timing is off?

Symptoms of incorrect ignition timing are poor fuel economy, sluggish acceleration, hard starting, backfiring, or “pinging” or “spark knock”. Too little spark advance will cause low power, bad gas mileage, backfiring, and poor performance. Too much advance will cause hard starting and pre-ignition.

What does a worn timing belt sound like?

The first sign of wear is “noise”. A tensioner that sounds bad usually is bad. While the engine is running, listen to hear if any noise is coming from the timing cover or front assembly. Bad bearings make a high pitched “whine” or “growling” noise after the engine has been started.

Excess slack in the timing chain can cause a rattling sound or even a clanking sound if the slack is severe enough to cause the chain to contact the timing chain cover.

Is it worth replacing a timing chain?

A timing chain runs inside the engine, as it needs to be lubricated by the engine oil. A timing belt typically needs to be replaced between 40,000 and 100,000 miles depending on the vehicle. … A timing chain doesn’t need to be replaced unless there is a problem with it.
