Accent MC (2006-11) :: Rebuilding A Motor Where The Timing Belt Broke While Idling
May 4, 2016
In the process of rebuilding a 2007 Accent where the timing belt broke while idling.
Pulled the head, ran a "water test" on the valves (put spark plug in, pour water on the valves and see if it comes out the exhaust/intake side) and found that only 2 intake valves were belt. Also shut off all the lights in a pitch black room, shined a flashlight in the intake/exhaust and didn't see any light leak from any of the cylinders except the one with the 2 bent valves.
Does this make sense? I would assume since 2 cylinders are always TDC at once, at least 4 valves would be bent.
Lastly, before rebuild I'll be replacing the 2 intake valves, all the valve stem seals, intake manifold gasket, exhaust manifold gasket, head gasket, head bolts and valve cover gasket. Anything else I should replace on the head? Trying to keep costs down as much as possible.
To add: Pistons have no damage on them, there are no marks of the valves hitting the pistons. The timing belt was replaced after it broke and the engine still ran however it ran rough. Compression test was done on only cylinder 1&2, 1 had 60 PSI and 2 had 0 PSI. Compression test was also done by just rotating the crank with a socket since I already had some of the engine disassembled.

Rebuilt a motor due to the timing belt failing. Everything works except I can't get the timing to line up perfectly.
From what I'm getting from the service manual, line the camshaft sprocket with the mark visible from the hole
Line up the crankshaft gear with the yellow mark at the bottom.
Do I have to do a double/triple turn of the cam/cranks to get TDC to be achieved properly? My biggest problem on this car is having the crank gear shift a couple teeth after tensioning the belt.

Looks like my timing belt broke. I was taking my car out of the parking lot, and heard the warning chime. I tried to look at the warning light, I think it was the malfunction one. I heard a belt/ fan snap. The engine stalled and I dint try to resart the engine. I had it towed to the dealership and am waiting to hear from them. The engine dint make mucg of a noise but sorta just died. Does this sound like a timing belt? I am worried abt the damage. how much would it cost if it was a timing belt? my car only had 73k miles on it. It is a 2001.5 1.8t.

The timing belt broke in my gf's '08 accent recently and I decided to have a crack at replacing the belt after getting a quote for $900 from the nearest mechanic (with no guarantee it would fix the problem).
When re-aligning the cam and crank to TDC, I wasn't sure if it mattered which revolution the crank was on (ie. 1st or 2nd revolution) when putting everything back together. I tested rotating the engine with the new belt on slowly to make sure there was no contact and everything seemed ok.
So basically now everything is back together, tried starting it up and it won't start and now i'm wondering if it would make a difference or not if the crank was rotated 1 additional revolution. Otherwise there is more significant damage.

1998 Mazda B2500. Timing belt broke while driving. How likely is it that my valves are warped & how do I fix it?

I have a 2007 Accent with 119K on it.
I wanted to replace the water pump and I was wondering if this can be replaced without removing the timing belt or the lower timing belt cover?

The timing belt went out at idle while making a turn. I changed the timing belt, but when cranked you have to pump the gas to keep it running and it is really rough running with a smell of gas when you turn it off. On the last run it backfired slightly. There is no knocking or pinging. And have triple checked the timing. Could improper torque on the crankshaft bolt cause this or failed ignition coils?

I am working with Honda dealership management because I had my timing belt changed at 102,000 miles and 25,000 miles later The belt broke and frayed while driving in heavy traffic at night on freeway leaving me stranded in the median luckily instead of in the middle of the freeway. Honda dealership stating that the idle tension pulley caused the fraying of the belt not due to poor workmanship by their mechanics. I am asking dealership to consider assisting in payment because the day the belt went out, the car had been serviced for a oil change.
When I was called to be notified the job was complete I asked the service rep questions about the oil transmission and told him there was a noise in the engine could they check it or did they check it which she replied no that I would have to make another appointment for that. So even if I would've made appointment the next day the damage was already done because that night is when the belt broke Is this part of Hondas responsibility is it reasonable for them to take part responsibility. Also if the idol tension pulley had been changed at the same time of the belt, it would've saved my engine. So this is all my responsibility not theirs?

Son has a 2004 Hyundai Santa Fe 2.7 motor. The timing belt broke before we could replace it. Long story short, 24 valves, gaskets, timing belt, water pump, new belt tensioner and new pulleys. The motor is back together. The only problem is when you turn the ignition switch on, it blows the CPU fuse. The only electrical part we replaced was the purge valve.

We recently had the timing belt replaced in our 2003 Volkswagen Passat (1.8T). Now it shakes and vibrates badly when we put it in drive and idle. It ran smoothly before we had the belt replaced. The mechanic hasn't found a solution yet.

I have just bought a 2000 passat 1.8t. The car had broken timing belt so i was just planning to replace the timing belt but there is another issue. When i was disassembling the radiator support I took off the intercooler but there was a lot of motor oil so I am not quite sure what is the problem. And do have to rebuild the engine or replace the cylinder head because of the broken timing timing belt. The belt was actually not broken only belt teeth are gone so I think that piston and valves might crashed.

Serpentine belt on a 2006 Honda Odyssey fraying and then ripping into the timing belt causing that belt to break? I recently had this scenario given to me as the cause of my recently replaced timing belt breaking.

Our pilot is 8 years old but has only 64, 000 miles on it. The dealership is recommending we change motor mounts and timing belt. Although the motor mounts don't seem to be broken and nothing is rattling we have to change the motor mounts due to the fact that the engine is moving more than an inch. Having said that in 6 months we have to put the pilot in long term storage for 3 years. Should we change the timing belt now given the low mileage and the long term storage situation?

I just changed the timing belt and everything runs great. I pushed the AC button and no light came on. I checked all the fuses and they are good I took the H and L caps of and tapped the pin and there was air blasting out. Don't know what it could be? All I did was loosen the compressor and remove the belt and put it back on.

I just finished replacing my timing belt, water pump and all belts. I made sure to double check the timing marks lined up via this pic:
Timing belt diagram
I put everything back together and no go. I am not sure what to do now. Should the crank sprocket pulley be in a special starting position? I see is has a "1" engraved on it.

My mechanic just did the timing bet, water pump and other belts. Also changed the tensioner.
Car runs fine and everything seems great until I get to a red light. The engine sounds louder then before. Not very loud but its louder and maybe a very slight vibration, not sure yet. No noises while driving, seems like its running the same or better then before. Runs fine though

Is there a "how to" on adjusting the tension of the timing belt in a 2002 accent 1.5L ....

Vehicle is an 08 Hyundai Accent 1.6L three door (hatchback) with 20,197 miles. This car was born on Oct. 16, 2007 and purchased in April of 2008. I told the owner to call the dealer and find out about when they should replace the timing belt as I had looked it up at the Gates site and found that it is an interference motor and also these Hyundai have some kind of lengthy warranty. When the tech or whoever she spoke to at the dealership asked about the mileage, they told her that she does not need to worry about the belt for about another five years, were rude and sounded inconvenienced by her calling. This leaves her with a bad taste in her mouth and more importantly, mis-informed.
I get the "Maintenance Log" out of the glove box and upon trying to decipher the timing belt interval, it states that the first course of action is an "inspection" at 30,000 miles or 24 months. How is a timing belt inspected? From what I have seen, a belt can look perfect today and snap tomorrow. But anyway, the next entry for severe service is replacement at 37,500 miles or 30 months which means this belt should have been replaced in October of 2010. Next entry is normal change at 60,000 miles or 48 months which puts us at April of 2012. After this it goes to 75,000 miles or 60 months.
I have already picked up the kit for changing the belt, tensioner, idler, and the two seals. How critical is it to change the spring as that was not included in the kit I got? I'm planning to do this job here in the next couple days as from what I can figure from the above log, It's way over due. I was reading some Hyundai forums and one stated that the 2011 model with the exact same engine calls for the first replacement due at 90,000 miles. How's this possible? Seems like these people (engineers) don't have all their stuff in one bag...

I bought a 02 accent base model hb 5 speed 109k miles for a winter car (have a mustang in garage.) It ran good until tonight when the timing belt snapped. I know this because while driving it made some ticking noises and then shut off and when you try to start it the noise that comes indicates no compression so the belt must've snapped and bent the valves.

2004 Accent 1.6L
Changed the timing belt and water pump this past weekend. I made sure the timing marks aligned before I put the belts on. They were still aligned after turning the engine by hand and still aligned after taking the car out for a test drive. I did not notice rough idle when I started the engine in the garage nor did I notice a rough idle during the test drive.
A few days later I am now noticing the car will idle roughly when I come to a stop. The idle will get rough enough to gently shake the car. No engine light and no unusual noise from the engine.
I am going to check the timing marks again tonight. I suspect the belt may actually be off by one tooth. I have driven over 100 miles since changing the belt so I don't believe it is off anymore than one tooth or else I presume I'd probably have already broken down or been hearing unusual noises.
Furthermore, I do not seem to have any loss in power. I still have good acceleration and no roughness unless at idle engine speed. I do, however, run rough at higher speeds (75+ mph) on the highway, but this was present before the timing belt change. Unfortunately the car does not have an RPM gauge.
Having said all of this, are there any other possible reasons why I might be idling rough now?
