Timing chains don't have a change interval like a timing belt. There usually changed when they become noisy. Here are the instructions on how to replace the timing chain in the diagram below. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Here is the deal,

September 2007 I purchased my Corolla from a less than upstanding used car dealership (apparently not a smart decision. live and learn) I purchased an extended warranty (not a dealership, but rather a private warranty)

February of 2008 It starts to make a high pitch banging noise in the engine. (I drive on it for about 2 weeks) I take it into a Toyota Dealership that.. I won't be returning to. They tell me that my engine was "essentially torn apart and reconstructed" and that it was the cause of my timing chain slippage. A month later, they were still fighting with the engine as they eventually found out that some gasket had lost a piece and it floated into the oil line (which took time for them to figure out). They instruct me not to tell the warranty company about this update, as it may jeopardize what coverage I was getting from them (about 400 dollars) I paid for the remaining 1300 dollars. My car was out of commission for over 3 months.

March 2009 Around a year after I got my car back (and about 1200 miles out of the warranty the dealership applied to the parts that they replaced) The engine began making the sound again. Well, 20 minutes later as I was driving down the highway the timing chain gets snapped by a bolt that had fallen into that area, sending it through a cascading effect essentially tearing my engine apart. Well, I decide to let the towing company take a look at it (as I didn't really want that dealership touching it) and the conclusion they came to was that some bolts had been stripped, others hadn't been tightened down enough, and others were just missing.

Well, I managed to skate out of a 3k repair bill by the skin of my teeth. The original warranty I purchased sent someone to take a look at the engine and determine if it was something they should cover. They decided it was the fault of the Toyota Dealership (as they were the last people to touch the engine aside from those doing oil changes for me) and refuse to cover it. Well, after talking to the manager at the Toyota Dealership, he grudgingly agrees to take care of it, as it sounded like something that was the fault of someone there. They re manufacture the bent valves, the stripped bolts, replace the ones that are missing, and replaced the timing chain and various other parts that the renegade bolt destroyed. This took about another 2 months to get fixed.

I don't have any documentation from them to prove that they touched my engine this time (as I didn't pay for any of it, they were unwilling to give it to me) so I am not even going to consider calling them, as I can't afford to live without my car for that kind of time again. When I picked the car up, the engine sounded fine for about a week, but then it started to run a little choppier (but not making a terrible noise, or a similar one to the last 2 times)

3 months later, I think my car is starting to sound like its going to happen again soon. (Its a high pitched metal on metal clang, but I can't tell for sure when it is in park, and I haven't had an opportunity for someone to get in and put it in drive to be 100% sure)

I'm about ready to consider replacing the whole engine and be done with it. I won't be recieving any financial aid from the warranty company to do so. (that would be too easy, right?) So I'm trying to put it off for as long as possible. I was also considering taking it to another Toyota Dealership and getting it looked at again. However I'm a bit reluctant to do so, as I am afraid that when I tell them what has happened they will be mildly uncooperative, or at least cover up something the other dealership screwed up.

My questions are: What could possibly be so wrong with the engine to cause it to consistently happen? If it is a problem with the engine, would replacing it be an effective option? Or perhaps would I be better off getting rid of the darn thing and letting it be someone else's problem?

Hi there,

Well this is a tale of woe..... Frankly i would be replacing the engine , for my money this should have been done in the first instance,the less said about these used car warranty's the better, but thats another story, why this has failed again is a bit hard to tell, you really need to be able to inspect the engine first hand, but when an engine is damaged so severely, the stresses set up with in the engine is considerable, with stripped and damaged threads, you only need one of these repaired threads to not take the required torque and they will quickly loosen and, well you know the rest, if you want to keep the car, fit a re-co long engine and be done with that bucket of bolts under the bonnet.....

Thank you for your timely response,

I'm having difficulty finding remanufactured engines that have a price tag on them... what kind of cost would be "reasonable" and do you have any suggestions as to a good location/website to get one?

I won't be replacing the engine immediately, however I'd rather not be scrambling to find a new one after the car has ceased functioning.

Check the sticker on the front of hood area.

If engine says VVT-i it is a 1ZZFE Toyota engine.

Look at sticker for confirmation and when buying a used engine, always have the VIN of the car.

Check with local junkyards for cost, but I would think $1,000-2000.

You usually get these from wrecked cars (rear ended).

Sorry you had so much trouble, but generally these are very reliable engines.

okay, well i have had trouble with my car trying to get it to run. i have been on this now for almost 3 weeks and to no avail. my problem was as i thought low compression because of out of spec cylinder bores, but now i'm wondering what the true issue is because i bought a short block from the wrecking yard because it had good compression and it checked out as in spec with my repair manuals specifications that's why i bought it because it passed the spec check. anyway i get home and install the cylinder head while the engine is on a stand and i take my time with this because i want to make sure it's right the timing that is and i finish and everything looks good. so i turn the motor over using a ratchet by hand about 6 times or so and recheck my timing marks and they are as i set them and i can feel some compression as i turn it over after i installed the spark plugs, but it doesn't feel as strong as it did when this short block was in the car at the wrecking yard. just as reference the cylinder head i also purchased out of the wrecking yard and it is in good shape too all valves had that grayish carbon coat on them that is telltale of a good running engine. i did however want to make sure that the valves were going to be reliable for me so i lapped them just to ensure that they would continue to operate properly down the road. now i'm beginning to wonder if my timing is incorrectly set though because each one of these short blocks that i had in this car over the last three weeks has come back with the same compression reading just over 100 psi per give or take 5 psi. although the first two measured out of spec but just barely out of spec the one i'm working with now should be compressing like it's supposed to these Toyota's wont run unless at least 145 psi is present and its supposed to be at like 215 or something if new or rebuilt. i thought i set the timing right still think i have but is there something anything i did wrong here maybe something to do with the intake VVTI cam gear? please help because i'm about to throw a flare inside this car and be done with it.

Hello again,

I know we discussed this before with the timing as the issue.

I attached the gear alignment for the cams and the crank.

Is this the way you set it?

The compression should be 140-160 I do not what manual you are referring to but this is reality and a lot of times, the reality is different than the book.

The 218 is for a new car, not a car with tons of miles.

As I stated before 140-160 is the figure.

Did you air test the cylinders as I suggested before?

i actually can't because i live in a community that is noise sensitive and i don't have a compressor here, but i'm going to get an air tank and do that next for the checking of any leaks anywhere. but if i crank the engine over for like a 15 count the compression will go up to 120 -125. but it should be stronger than that i used to get good readings on cars. i have previously worked on after a three count. just out of curiosity what is your opinion on that? and thank you for the help by the way.

You should have about 140. 100 is too low. You have to find the issue.

Hi I had a strong slapping noise coming from the timing chain, so I took off the tensioner and the timing cover. Chain was loose(even b4 taking off tensioner), and I can move the tensioner pretty easily. Sounds like I needs the chain and the tensioner to be safe, but could you tell me how to re-time it, as far as the marks on the cams/crank/chain. Thanx.

You can remove the valve cover and look at the chain with a light source. Look for broken teeth on the cam cogs.

Chains will generally last the life of the car, but they can go bad.

Do you have a check engine light? If so, what codes?

REMOVAL:
Disconnect the negative battery cable. Wait at least 90 seconds once the cable is disconnected to hinder air bad deployment.
Remove the right front wheel and engine under covers.
Slightly jack up the engine on the right side to remove the RH engine mount. Inspect the mount and replace if necessary.
Remove all drive belts.
Remove the valve cover.
While retaining the crankshaft pulley, remove the pulley bolt. Extract the crankshaft pulley using a puller.
Unbolt all three timing belt covers from the engine.



INSTALLATION:
Check that the timing belt gasket has no cracks or peeling. If the gasket is not reusable do the following:
Using a flat-bladed tool and gasket scraper, remove the old gasket material from the cover and mating area.
Thoroughly clean all components to remove all the loose material. Remove the backing paper from the new gasket and install the gasket evenly to the part of the cover shaded black in the illustration.
After installing the gasket, press down on it so it seats and the adhesive firmly sticks.
Install all three timing belt covers and tighten the bolts to 62 inch lbs. (7 Nm).
Install the new valve cover gasket and seal washers to the cylinder head cover.
Install the cylinder head cover to the cylinder head; secure with four cap nuts to 53 inch lbs. (6 Nm).
Install two PCV hoses to the valve cover; secure with hose clamps.
Attach the engine wiring harness to the valve cover, then install the engine wiring harness cover and secure to 53 inch lbs. (6 Nm).
Connect the wire and clamp to the alternator.
Install and adjust all the drive belts.
Install engine mount to body and secure but do not tighten fully. Tighten the following:
Mounting bracket-to-engine mount bolt to 47 ft. lbs. (64 Nm)
Mounting bracket-to-engine mount nuts to 38 ft. lbs. (52 Nm)
Engine mount-to-body bolt A to 19 ft. lbs. (25 Nm)
Engine mount-to-body bolts B to 19 ft. lbs. (25 Nm)
Engine mount-to-body bolt C to 19 ft. lbs. (25 Nm), if equipped with cruise control.
Install the right engine undercover.
Install the right front wheel and lower the vehicle.
Connect the negative battery cable.
Start the engine and check the ignition timing. Inspect for leaks and check vehicle operation.

So we received a car from a guy for doing some work for him and the car sat in his driveway for almost 5 years. Upon putting a new battery in and trying to start it. It cranked but would not start. We put a little fuel in the throttle body and it fired up. So we assumed we had a fuel problem. We towed it home and started to work on it and clean it up. We replaced the fuel filter and we found a blown EFI fuse. We replaced but still would only crank but we still weren't getting fuel so we pulled the tank and removed the fuel pump and it did not work so we replaced it and cleaned the tank and flushed and cleaned the lines. Now we have plenty of fuel up to the front with still no start. Checking the ignition we had spark on four cylinders. But after watching some videos we thought maybe it wasn't strong enough so we replaced the ignition coil. Still no change in starting. We are at a loss. We also checked compression which was the same all across the board. So we have compression, we have spark, and the plugs are wet so we definitely have fuel. At a loss of what else it could possibly be. Please help.

Hi,

There is a chance the fuel injectors are not getting a signal to inject fuel or they are clogged from old fuel. If it starts when you feed it fuel, then it isn't an ignition problem. At this point, I suggest two things. First, I need you to check for diagnostic trouble codes. This vehicle has an OBD1 system and you don't need a scanner to get codes. Take a look through this link. It explains how to get codes from the computer.

https://www.2carpros.com/articles/toyota-trouble-code-definitions-and-code-gathering-method-1990-1995

Do that first and let me know what codes are found.

Next, I need you to check for an injector pulse. Here is a link that will explain how to check for a pulse. If there is one, you will need to remove the injectors and check their condition. If you continue through this link, it will show you how to test the injector one it's out of the vehicle.

https://www.2carpros.com/articles/how-to-test-a-fuel-injector

Okay, that will get us started. Here are a few links you may find helpful when testing:

https://www.2carpros.com/articles/how-to-use-a-test-light-circuit-tester

https://www.2carpros.com/articles/how-to-use-a-voltmeter

https://www.2carpros.com/articles/how-to-check-wiring

Let me know what you find or if you have questions. Also, see if you use starting fluid to get it started if it will stay running. If it does, there could be an issue with the cold start injector.

I will watch for your reply.

When we first tried it with regular fuel in the throttle body it tried to start but then it suddenly stopped trying to fire. We did find a blown EFI fuse but it was replaced. We definitely have fuel in the cylinder now after changing the fuel pump, the fuel filter, and flushing the lines. The plugs are wet with fuel when we pull them out now so I know there is fuel getting into the cylinder. We also checked the spark by pulling the plug out and grounding it and they all seem to have good spark. It's odd it has spark, fuel, and compression but no fire.

Hi,

Okay, if you have spark and fuel it should run unless one of the following is an issue.

Low engine compression

Engine timing off (which usually will make it sound differently when cranked)

Fuel pressure is too high and flooding the vehicle.

If all of the above checks good, the engine has no choice but to run, so we are missing something. Do me a favor. Record the engine when you are trying to start it so I can hear what it sounds like. If to you it sounds normal, then I need you to perform a compression check. I would also confirm fuel pump pressure isn't too high.

_______________________

Here is a link that shows how to perform a compression test. You will need a compression gauge, but most parts stores will lend or rent one to you.

https://www.2carpros.com/articles/how-to-test-engine-compression

I would also just confirm that fuel pressure isn't too high. There could be an issue with the regulator.

I can usually tell if there is a timing issue just by hearing it. So, if you could record it, I may be able to tell. If that isn't an option, then the compression test is necessary. If timing is off, compression will be low. Please understand there are other things that can cause low compression such as a head gasket, but in most cases, that would not affect all cylinders.

One more thought. When you checked spark at the plugs, was it a hot blue snapping spark or was it more orange or white in color?

If the timing belt jumped or has broken, it will need replaced. I have all the directions step by step, so let me know if that is an issue. You may need to remove the timing belt cover to inspect it. I do have good news in all of this. If it is the timing belt, it really isn't that big of a concern. These engines are non-interference engines which means there won't be internal damage. So many cars today are the opposite.

Let me know what you find. I will watch for your reply. Don't worry, we'll get it running.

Thank you for your help. We really do appreciate it. The compression check showed 110 in all cylinders after about 3 cycles. We did try disconnecting the injectors and it still would not start with the fuel that was in the cylinder. I will try to get a video of it tomorrow but it does sound like it cranks for a few seconds and then chokes. We try again and same thing. We open up the oil fill and see the cam spinning so we know at least the timing belt is not broken. Thank you again for your help and I look forward to hearing what you have to say.

The choke sound could be related to timing if it is firing at the wrong time. I will wait to hear it. With that much compression, fuel, and spark, it should start. I have a feeling that we jumped time. Please reconfirm the spark. Make sure it is a hot blue spark.

Hi,

It sound normal cranking except at the very start. By any chance, did you turn the distributor? Does it always act the same way?

At the start of your video, it sounded like there was a timing issue, but it went away. To me, it sounded like it was firing at the wrong time. After that, I didn't hear any firing.

Let me know,

It normally will sound like it's trying to crank then bogs out. Then you try again and then it bogs out. We did remove the cover from the timing belt and when the crank was at TDC the dot on the cam pulley was at about 2 o'clock and I think that is suppose to be straight up. Not sure on that if you can confirm. We ordered a new timing belt and are going to try that. No we did not remove the distributor just changed the coil in the distributor and checking the cap and rotor. Thank you again for your help.

Thank you very much for your help. we changed out the timing belt yesterday and it started right up. The timing belt ended up jumping almost 5 teeth. Thank you for pointing us in the right direction and checking the alignment of it. We assumed that since it was turning the cam that the belt was good but didn't realize about it jumping teeth. Now it just appears that the alternator is not charging at all so on to the next thing, lol...
