No, it is not an interference engine. It also uses a timing chain, not a belt.

SOURCE: how to replace a timing chain 2000 chevy cavalier

I am familiar with that vehicle but generally with timing chain replacement, the engine needs full access for pulley and cover removal and in some cases the cylinder head requires removal.
Generally timing chains last so that they only need replacement at engine overhaul and it is not an economic proposition to have to replace a chain unless some relative degree of engine work is also required at that time. 

Engine timing chains generally have a tensioner on them which maintains tension, but some chains can wear significantly and cause timing cover to be "ground away" because of "slop".

If the engine is making the noisy rattle of the timing chain against the cover etc, I would schedule a top overhaul (head, machine, test and valve grind) with the chain replacement dependent on mileage with the degree of action.

Some simple simplex timing chains (type of chain similar to motor bike chain) may be replaced without dismantling the engines but I would expect your chain would be a "duplex" dual sprocket type, these are most common. 
These chains are not generally expensive but replacing them can involve a fair amount of work. 

Good Luck and hope this helps, Others will have different ideas.

SOURCE: timing belt broke -2000 ford focus zx3

Hello mawbea: My name is Roger I will answer your question. You did not say which engine is in your car. So if you have a 2.0 SOHC engine. If the belt broke you should be Ok. If you have the 2.0 DOHC engine. The likely hood of bending the valves are just about a guarantee. How ever with any engine using a timing belt it is possible to bend a valve.Should you need more help please just ask.
Please rate the quality of your answer as this way we know you received helpful information.Thank You for using Fix Ya, Roger

SOURCE: Is the engine a non interference engine? Trying

Dear Unsure About Timing Belt Replacement......You are CORRECT ...this xterra motor does have whatthey call an interference engine in it.......and yes it does require exact placement and alignment of the cam to crank timing marks. Cam lock stabilizers are invovled for a pain free install of the timing belt.... If you have never done one before I would suggest that this not be your first attempt......try smaller and work up to something like this.......If you do need any more help though please get back to me....thx for your time!!!!!HOPE I COULD HELP!!!

My timing chain has snapped


I assume it's your timing belt, not a chain, which rarely, if ever snap. Depending on the make of the car and the engine you may, or may not, have serious engine damage.. DO NOT ATTEMPT to start the car, have it towed to your shop of choice. If there is no engine damage a timing belt replacement generally will run you 2 or 3 hundred bucks...if you did serious engine damage you may have to decide if the car if worth the money to have it repaired. What you need to know is whether your car has an "interference" or "non-interference" type engine.. In an interference type engine if the timing belt breaks the valves will "interfere" with the pistons as they travel up if the timing belt breaks, which results in generally catastrophic engine failure.. non-interference engines generally suffer little or no engine damage with a broken timing belt.. I broke a timing belt on my 1990 Toyota Supra going 70mph, but it was a non-interference engine and after having the belt replaced it was fine.. here is a good list someone put together on what type of engine is in your car.. you should find the engine type either marked on the engine or on a label under the hood, or the owners manual.. good luck. http://yourcarangel.com/2014/07/interference-engines-complete-list/

Is it an interference or noninterference engine? Think timing chain has broke


Broken timing chain is a very large problem, if it happened while engine is running. Bent/broken valves and such. Makes a LOT of noise, and engine stops immediately.

Your question doesn't include make/model/year, so your question isn't possible to answer. Doesn't really matter, though, if your timing chain broke. That's pretty rare. Timing belt, yes. Chain, no.

Does the 1999 chevy cavalier use a timing belt or timing chain and if it brakes do the valvle hit the pistons or is there clearance


It has a chain if it is the 2.0L or 2.4L four cyl . And they are not interference. The V6 model is also chain drive and is not interference.

If the timing chain is broke, dose the engine have to come out to repair it.


no you don't need to pull the mtor, the front of the motor must come apart after removing the radiator and all belts. There is a chance if the timing belt broke the cylinder head's valves may be damaged call the chevy dealership and ask to speak to the service dept. ask them if your year make and model car has an interference motor in it, if it does have one there's a good chance you bent a valve or two at the time of the belt breakage.

What do you mean by high mileage on a 2003 chevy cavalier as far as a timing chain having to be replaced? My cavalier has 173000 miles on it- does it need to be replaced? Or do I wait or what?


Here is the scoop
Went to another web page, says the 2.2 and the 2.4 are non-interference systems.
So when the chain jumps, the car will stop, but you will not damge the valves.
So drive it till it stops, then change it, it's a big job that you may never have to do.
