Don't know what vehicle you are talking about but with most vehicles if the timing chain jumped you won't get out of your driveway. With the timing cover off, most chains and gears have marks stamped into them that should line up when the number 1 piston is at Top Dead Center.
It will become noisy and you will hear it. Also you may experience poor performance if the chain has jumped a tooth.
It will be noisy or may have jumped time. The only sure way is to remove the cover and inspect it.
If the timing chain or belt jumped time one tooth or notch it would lose most of it's power. If it jumped two teeth or notches it wouldn't have the power to move at all.
You will know if your car has jumped timing by the way it starts up. If the engine is slow and sluggish, it could be a sign of jumped timing. Also listen out for strange noises coming from the engine or if it backfires, it is likely that there has been a change in the timing sequence.
That engine uses a timing chain. Chances are very slim that the chain jumped time. However if it did jump time the engine would not run and the engine would have no compression. Tell us what the symptoms are.
Not sure what engine you have but it is highly unlikely the timing would jump being that it is driven by a chain. If it was to jump it probably wouldn't start and possibly backfire in the attempt to start.
No such thing as a timing chain belt. It is either a belt or chain. Replace the belt according to the schedule in your owner's manual. If it breaks and your engine is an interference engine, you will 95% of the time have damage. You will know the extent of the damage when the engine is torn down. The 1992 SL2 has a timing chain. Mine has 240,000 miles on it and is still running fine.
It is possible for it to break, but highly unlikely, especially if you perform oil/filter changes as you should. Normally the timing chain will last the life of the engine and is not an item you replace. But on your Saturn it is critical that the oil/filter be changed exactly as listed in the owner's manual. The timing chain may also come into contact with the timing cover, causing noise in the engine. The only way to know for sure if the chain needs replacing is to look at it. If you do that, you might as well just replace it.
Timing chains rotate, much like that of a bicycle. It would make a loud clanking sound. Now it may have "jumped" off its position or may be worn out. or get a compression test,plus you'll know the car won't start likely it's the timing chain causing it.
Need to know where the timing chain gear marking are?
I need to know where the timing chain is located in a 1988 Olds 98 regency brougham, and how expensive a timing chain is.
