I believe by 2000 interference motors are no longer, but anytime you drop a timing belt when the engine is running at 2,500 RPM's that is hard on the valve train.
I would replace the belt and try it out.
Let me know if you need the procedure, and how it goes.

What are the chance that I will not need a value job after timing belt broke


A "valve job" typically means resurfacing the valve seats. It is unlikely you would need that after the timing belt broke unless you needed it before the timing belt broke - they aren't related wear items. Depending on the engine (if it is an "interference" engine) you may need new valves or a new top end of the engine because the valves may collide with the pistons when the timing belt breaks, causing a lot of damage. If your engine is not of the "interference" design type, then you probably only need a new timing belt; many shops also recommend replacing the water pump too because its failure can often damage even a new timing belt and there usually is no (or very little) additional labor cost involved. Other maintenance might also be recommended at the same time (like replacing spark plugs), but that too depends on your specific engine.

2000 saturn ls time chain replacement


What exactly do you need to know about replacing the timing chain? Also you should note that the L200 (4 cyl) has a timing chain. The L300 (V-6) has a timing belt.

Another thing to note is that both of these are interference engines. If your timing chain (or belt) has failed and the engine will not start, the valves are likely bent and you may have damaged the pistons as well.

Timeing belt broke have replaced now not fireing


You either have the belt 180 degrees off. So you have to take belt off and turn crank only (slowly) around once to its mark again, but first you need to go to a website that lists motors that are called "interference fit" engines. (Think Gates belt co. has a list) If your motor is an interference fit then when belt broke the motor is trashed. Interference fit means that pistons can hit valves if the belt breaks. That is why they tell you to replace the timing belt before too long. Also if motor is interference fit when you try and turn crank go slow because you may bump into valve.

I have a 2003 isuzu rodeo, and the timing belt broke. its a 2.2l motor. I have no compresion and i think its the head. is there anything else besides the head that i need to be aware of when fixing my...


Don't condemn the head just yet.

When the timing belt breaks, the camshaft stops turning, so the relative position of valves doesn't' change if you try cranking the motor over. Any valves (intake or exhaust) that aren't fully seated will allow pressure to "blow by" that other wise would form the compression you say you no longer have.

What I'm not sure of is if you have an "interference" motor. An referenced motor is one in which the piston can strike a valve head when the timing belt breaks. The clearances are so close that all moving parts have to be in perfect sync in order to operate and not strike one another.

It is possible, with an interference engine, to break valves and / or crack a piston if attempting to crank and the piston comes in contact with an open valve.

If it isn't an interference engine, you shouldn't have any problems. Just get the cam and crank (and any other shaft(s) that may be belt driven) in proper timing, install a new belt, apply the correct tension and you're basically "good to go"

I'd suggest you purchase a vehicle specific repair manual at your auto parts store. It'll contain step by step instructions specific to your vehicle on how to perform this repair.

Good luck!

I have a 2003 Saturn vue with 138,000 miles. the machanic says the cam shafts are not turning and the timing belt is broken . How expensive is this to do, can I do it myself ?


First you need to find out if the engine is an interference engine or free running. If an interference engine, it means the valves will interfere with the pistons if they become out of time--like when a timing belt breaks. this means the valves will hit the pistons and vice versa. Usually the valves are bent and the cylinder head must be removed to get to the bent valves and replace them. If the engine is free running, the valves and pistons will miss each other if they become untimed. So all that is needed in this case is a new timing belt. Much, much easier and less costly than removing the cylinder head.

To find out if your engine is free running or interference, check out this website:

scroll down and look for the interference check.

When is timing belt supposed to be changed?


2006 Saturn Vue with a 3.5L engine V-6, Saturn recommends replacing timing belt every 100,000 miles, also replace water pump, due to it is timing belt driven, this is an interference engine which piston to valve damage will occur in the event of timing belt failure.Hope this was very helpful.

Timing belt is broken. Interference or non interference motor?


Most Ford vehicles from 1985 and up have enough valve clearence so the valves do not get hit when the timing belt snaps. Since I worked for ford for many years I have only seen one with valve damage and the youg man said he was driving his car really hard at high RPM's. I believe you will be okay on your engine as long as when the belt broke the engine was not at high rpm's. If know one has told you those engine recommend a timing belt replacement every 60k. I hpe this helped and I hope this fixes your problem. Good luck, Roger

Is the Saturn 2000,LW2 3.0 v6 a free running motor, meaning if the timing belt breaks will the motor be OK. Tom


According to my research it is an interference engine. Meaning if your timing belt broke, you could have damage to the valves and pistions.

1998 kia sportage. changed timing belt. now no compression.


WOW - DID THE BELT BREAK WHILE IT WAS RUNNING IF SO THE VALVES ARE BEND THATS WHY YOU HAVE NO COMPRESSION.
IF YOU HAD THE BELT REPLACED AND THEY DON'T HAVE THE TIMING MARKS RIGHT YOU CAN STILL BEND THE VALVES.
9 TIMES OUT OF 10 THE DAMAGE IS JUST TO THE VALVES AND NOT THE HEAD OR ENGINE. BUT IF YOU HAVE TO PULL THE HEAD MY ADVISE IS TO HAVE THE HEAD CHECKED FOR CNY CRACKS

2001 kia sephia timing belt DOHC 1.8 T8


If your timing belt came off when the motor was running, there 2 possible scenarios:

Motors are interference (pistons hit valves if motor spins <=2 revolutions without a functioning belt/chain) or not.

1. if kia 1.8 motor is an "interference" engine ... major damage already occured, at best valve stems are bent and you have to pull the head to install new valves, at worst, a piston now has a hole in it and you get to do a full rebuild.  I'm now praying for you;~).

2. if it's not an interference engine ... joy is you,  you rotate the cams whichever way you want and pistons do not hit valves ... and as they say in England "Bobs your uncle" ... ask a Brit.

I'm guessing that Kia doesn't build an interference motor with a belt ... the dealer or any shop with access to a good paid automotive database can tell you if the motor is interference or not. 

The standard explaination for rotating forward ... which is not necessarily clockwise, has to do with tensiong the belt and how you get the tensioner in the correct position to do its job ,,, which is to keep the timing belt from jumping teeth.  Each motor can be slightly different for tensioning the belt, so you need the specific instructions for your year car with the 1.8 motor.  If the manual says you need special Kia tool "XYZ" ... get it or an close equivalent, don't try to use a pair of vicegrips clamped to a  screwdriver. 

You need to spend $20 for a Haynes manual for your car.  Now you or I might think for a minute that what they say in the haynes manual isn't the easiest way ... but then we would probably be wrong. 

Having done several timing belts, engine rebuilds and general maintenance over the years ... I can tell you this sincerely ... advice from someone (haynes in your case) who has actaully done the job you are embarking on is worth more than $20 if you are doing a job that takes more than a couple of hours.  The specific stepwise instructions they have will get you successfully to the place where you have a new timing belt and the motor runs right by the shortest path.   And one of the biggest benefits in doing a job of any complexity, it that you have written stepwise reassembly procedure documented ... so you don't end up at step 17 in the reassembly ... just to realize you didn't do step
9 .. that now requires to take stuff apart for the second time !^%$@!

Good luck ... you'll feel great when the thing is purring again.
