What happens when a timing chain jumped a tooth?
An engine with a jumped timing chain will show signs of very sluggish and slow starting. This happens because the firing sequence is retarded due to a chain that has jumped a tooth. A chain that has jumped two or more teeth may not start at all.
What happens when a timing chain has jumped two teeth?
An engine with a jumped timing chain will show signs of very sluggish and slow starting. This happens because the firing sequence is retarded due to a chain that has jumped a tooth. A chain that has jumped two or more teeth may not start at all. Step 2
What to do if you have a jumped timing chain?
Place the vehicle in park with the emergency brake set. Start the engine but be sure the battery has a full charge and is operating at peak performance. Note the speed at which the engine tries to start, comparing it with a normal start condition. An engine with a jumped timing chain will show signs of very sluggish and slow starting.
Do you need to check distributor timing after installing new chain?
At this point, you should check the injection pump timing on diesel engines and distributor timing on gas engines to make sure that did not move as well. It is a good idea to do this anyway after installing a new chain because that can affect both injection pump and distributor timing.
Why does my timing chain rattle when I start my car?
Chains that have slipped time have slackened and can sometimes rattle during cold start or idle, or produce a swishing or scraping noise. Loose chains typically hit the inside of the timing chain cover. A rough running engine may accompany such noises.

How does the timing chain in a car work?
How Your Timing Chain Works. The timing chain connects the crankshaft to the camshaft(s). It keeps them running in sync. It ensures that the piston is close to or at top dead center at the moment of combustion.
