Is replacing a timing chain bad?

Unless the timing chain is broken, stretched, or otherwise compromised, there’s no reason to change it. If there is something wrong with the timing chain, your car will likely exhibit one or more problems. Symptoms of a failing timing chain include: Timing chain noise.

How much is a timing chain for a Chevy Cavalier?

The average cost for a Chevrolet Cavalier timing chain and gear set replacement is between $784 and $913. Labor costs are estimated between $493 and $622 while parts are priced at $291.

What happens when timing chain goes bad?

A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves. The valves themselves will bend and potentially ruin the engine.

What does a worn out timing chain sound like?

Listen for a metallic sound that resembles a rattling or scrapping noise. The sound can be intermittent or constant, but it will be a metal to metal contact. If you hear a rattle, metal to metal slapping or scraping coming from inside the cover, it indicates a timing chain noise.

Is it worth fixing a timing chain?

Unless there is a specific problem, the timing chain normally needs to be replaced between 80,000 and 120,000 miles. If you drive an older vehicle, or one close to 100,000 miles, you should have it replaced or at least become aware of the symptoms of a failing timing chain.

What is the average cost to replace a timing chain?

Typical costs: Hiring a mechanic to replace a timing chain typically costs $300-$1,000, depending on the make and model of the vehicle, its age and whether the work is performed at a dealership or an independent shop. Purchased separately, a timing chain typically costs $50-$250 or more.

How much does it cost to fix a timing chain?

How long can you drive with a bad timing chain?

The timing chain normally needs to be replaced between 40,000 and 100,000 miles unless there is a problem.

Can a timing chain be tightened?

Timing chain’s have no tensioner, are made to fit, and cannot be tightened. When a timing chain is stretched too far, you purchase a timing set (chain with matching crankshaft & cam gears, as they MUST be changed together. Many engines that run chains have a hydraulic tensioner.

At what mileage should a timing chain be replaced?

between 80,000 and 120,000 miles
The timing chain normally needs to be replaced between 80,000 and 120,000 miles unless there is a specific problem. Issues with the chain are common in higher mileage vehicles.

Is a timing chain expensive to fix?

How are gears connected to the timing chain?

Locate marks on your crankshaft and camshaft gears. These gears are connected by the timing chain so that the position of the piston (connected to the crankshaft) correlates directly to the opening of the fuel and exhaust valves (operated by the camshaft) to keep your engine running smoothly.

How to know when your timing chain has jumped?

1 Noise – A good indication that a timing chain has jumped is going be noise. 2 Performance Decrease – The engine timing is going to be affected when the timing chain jumps. 3 Service Engine Soon – Your vehicles ECM may or may not have enough input from the engines sensors to detect that the timing chain has jumped. But, it often does.

Do you need an owner’s manual to change a timing chain?

Locate your owner’s manual. You will most likely need it to disassemble and reassemble various parts. Also verify that your model is equipped with a timing chain and not a timing belt. These two parts perform the same task, but replacing them can be quite different. This procedure is only for replacing a timing chain.

Can a loose timing chain cause an engine to backfire?

Backfiring If your engine backfires, it could be due to a loose timing chain. If your vehicle loses power, without warning, your timing chain might be loose. If you notice your engine running rough on idle, or while you are accelerating, this is another sign you may have a loose timing chain.

When to replace timing belt and gear set?

Don’t take a chance reusing an old timing belt, chain or gear set. A high mileage timing chain that has stretched and is loose can’t maintain accurate valve timing and should be replaced if play exceeds specifications. The camshaft and crankshaft sprockets should also be replaced along with chain.

When do you Know Your timing chain is failing?

When you have your oil changed, and the mechanic tells you there were small pieces of metal inside the oil as it drained or in the filter, it’s a good indication that your timing chain is beginning to fail.

Do you need to change timing chain on OHC engine?

On OHC engines that use a timing chain, the timing set may also include a chain damper or tensioner. The chain damper, tensioner, guide or rails should also be replaced when the chain and sprockets are replaced because these components play a vital role in supporting the chain and keeping it tight.
