Can a check engine light be a bad timing chain?
The check engine light can illuminate for a variety of reasons, one of which could be a failing timing chain. A car’s computer will display warning lights that must be checked and scanned for trouble codes to determine the source of the issue.
What causes oil to separate from the timing chain?
Over time, oil begins to separate as it heats up and is exposed to natural solvents found in gasoline. If the timing chain begins to wear out, small metal pieces can break off the chain and find their way into the oil pan.
Is the timing chain on an engine made of metal?
In order for your engine to fire, the timing chain must smoothly rotate around the gears without hesitation. Although the timing chain is made out of metal, it is subject to wear and tear and may break if not replaced as recommended by the manufacturer.

Why does my timing chain make a tapping noise?
Check for a break in the gasket of the tensioner, between it and where it bolts on, that will allow oil pressure to bleed out and not give full pressure to the tensioner. Thing is the car only makes the tapping noise when the car is at full operating temp which i would assume when the oil is at its thinnest.
Can a bad timing chain cause an engine to misfire?
Engine misfires. The timing chain method is more common with consumer vehicles and high performance engines. Over a period of time, the timing chain can stretch, which can cause the chain to skip a gear on the cam or crank shaft. This results in the engine’s timing to fall out of calibration and often results in a misfire.
How does a timing chain tensioner work when not running?
The tensioners are kept tight with oil pressure when the engine is running. The oil drains back when not running, but some tension remains on the chains from the spring inside the tensioner until it starts and is pressurized. I have gotten almost everything off the front of the motor.
Can a timing chain be replaced on a pushrod car?
In old-style pushrod engines, replacing the timing chain is a fairly easy task. No such luck if you have a modern front-wheel drive car with a transversely-mounted engine, as the space in the engine compartment could be very tight.
When do you know to change the timing chain?
A timing chain runs inside the engine, as it needs to be lubricated by the engine oil.

A timing chain doesn’t need to be replaced unless there is a problem with it.
How to troubleshoot a chain or sprocket problem?
Improper installation of the sprocket or axle. Inspect and correct. Chain casing or bearings are loose. Tighten all bolts and nuts. Excessive or insufficient slack in the chain. Adjust the distance between axles to obtain the proper amount of slack. Excessive worn chain or sprocket. Replace the chain and sprocket with new chain and sprocket.
What to do if your chain is not installed correctly?
Improper flex or bending of chain, tight joints. Chain is not installed correctly. Inspect the installation and correct as necessary. Contamination from metal dust or dirt because of improper lubrication. Remove the chain, wash it thoroughly, and provide proper lubrication.
What causes the pin to come out on a chain?
Operating a chain at high load without proper lubrication can create friction between the pin and bushing, causing the pin to rotate. In this condition, the pin may come out, leading to chain breakage. Replace with new chain immediately.
