How do you know if timing chain is broken?
Remove the cover of the engine valves to allow you to look at them. Start the engine. If the valves are not moving when you try to start the engine, that means that the timing chain is no longer alerting the valves on when to open and close, meaning that your timing chain is broken.
Can a timing chain be out of sync?
This can be a big deal and you can damage the valve if you try too hard. Normally you would set the engine up on the timing marks before removing the timing chain, and not turn the crank or camshaft until the new chain is installed. If the crank and cam are out of sync the valves can interfere.
What happens if you try to turn a crankshaft while timing chain is off?
If you are trying to turn the crankshaft while the timing chain is off, you may have an open valve that is hitting a piston. This can be a big deal and you can damage the valve if you try too hard.
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 belt typically needs to be replaced between 40,000 and 100,000 miles depending on the vehicle and it’s a few hundred dollar repair. A timing chain doesn’t need to be replaced unless there is a problem with it.
How can you turn the cam without turning the crank?
I always though you turned the crank with a breaker bar until the cam gear was in line, then take the chain off and turn the crank until it is in line. They should line up at 6 for the cam and 12 o clock for the crank. Ok thats how I have done it 3 TIMES… (its really making me mad if u cant tell, lol).

Why do you need a timing chain on your car?
The timing chain keeps the camshaft (s) and crankshaft in sync. For your car’s engine to run properly, the valves, which are operated by the camshaft, need to be timed with the movement of the pistons that connect to the crankshaft.
