Broken timing belt can cause significant damage. Bent valves and possible damage to cylinders. I would seek another mechanics view. It is unusual for a belt to break with such low K's. You could have a mechanic visually check for damage by removing the head or weigh off the cost of putting a new belt in and having the mechanic check each cylinder for compression. Likelihood of damage is greatly dependant on the engine design if there is no clearance between piston tops and valves significant damage is much more likely. Do consider another mechanic in my opinion.

that might be a funny coincidence if your buddy knows whats up then it just might be a sensor that would be my guess, check your fuses just to be safe.

SOURCE: engine cranks car won't start

Sorry..... 1 notch off is just not good enough. It has to be exact , then if it doesn't run start looking at other posibilities.

Remember that the camshaft turns twice eash time the crank turns once. The distributor rotor works off a gear on the cam.
Your rotor could be off a bit , or it could look exactly perfect the way it was when tou took it out , and still be 180 degrees off.
You have to get your engine to "top dead center" and make sure everything is the way it should be.

A timing chain ( or belt ) can cause permanent and fatal damage to the valve train and pistons in motors that are "interference engines" Find out weather yours is. In a non-interference engine , the clearance between the valves and the pistons is large enough to alow them to move out of time without crashing into each other. An interference engine is not so forgiving.

The fact that your engine cranks makes me hopefull that it is a non interference engine , and that damage has not been done.

Try to find a haynes manual for you vehicle , it will walk you through the steps for most repairs.

SOURCE: timing belt or timing chain?

You 98 Corolla has a timing chain that it internal and need no normal maintenance. It uses a hydraulic/spring tensioner to keep things tight and as long as its quiet, everything is fine.
Your drive belt (not to be confused with a t. belt) is the external belt you see on the passenger side of the engine. It drives you alt, water pump, A/C and power steering. It uses a spring loaded tensioner to keep the belt tight. These can weaken over time and cause a rattle noise and belt slippage.

My 2003 kia spectra jumped time, It don't sound like rods are bent! Is it worth trying to fix?

If it jumped the timing. more then likely it would bend the valves first before a rod. it is worth fixing if all it needs is a new timing chain/ belt and put new gears on also. as long as nothing internal happened it will be fine.

Taurus timing belt

It's rule out jumped timing mark first.
How may miles is on this T-belt?
If it is over 100K miles and care for then it can be a jump belt.

Open the timing covers.
Set cylinder 1 to top dead center
The two cam DOTS should line up.
If it does not the you has a jumped belt.

The only corrective action is to change the timing belt.

Is there a way to check the timing chain without removing the cover ( this is quite a job) for a look at the timing marks

no way of doing so. need to remove cover. i have been doing this since 1996 and have never seen chain driven nissan jump timing. have seen some timing belt cars jump, but never chain driven engines. i think you have something else going on. i have done many and many timing chain jobs on frontiers and maximas, but not for a timing chain jumping issue. upper timing chain shoes wear out and engine gets noisy. i have to say i have seen some with the primary chain stretched a bit, but car still ran fine.

Had timing belt with the full maint on it in 2003

I have a 1997 malibu that has 260,000 plus miles on it, and i have never replaced the timing chain. Now, i'm not telling you not to do it, but if your car is running fine, a regular tune up will sufice(plugs, air filter, and wires if equipped). DON'T get taken advantage of, if you suspect that it may be something major as the timing chain going bad, get many opinions and don't settle for the first one out there. It's your hard earned $1300. If the chain was replaced in 2003, you should't need it unless the car is running terribly and the regular tune up doesn't help. It's good to up keep your vehicles, but if it sounds too much or suspicious to you, get another opinion.
