1992 Acura Legend, when the timing belt goes, is it common for the valves to bend?
I brought my 1992 Acura legend to my mechanic because the timing belt went. He called me a week later saying that when the timing belt went it bent my valves. He also told me this is very common for this car. I'm just looking for a second opinion. This would be the second time the timing belt has gone and I don't remember the valves being bent when I had it replaced the last time 8 years ago. The car is low mileage for the year, only 153k miles for a 1992. It's not driven hard either. I already purchased the timing belt, seals, water pump, and thermostat. How much should I be look
Experienced mechanics share their insights in answering this question :
If the timing belt break off, the engine’s pistons will hit the valves as the pistons are moving. The engine is an interference engine and can cause damage to the internals of the engine. The last time the belt came off, the engine may have been running at an idle or not under power. It is possible for the valves to be bent. What I recommend doing is performing a leak down test on the engine with a timing belt on the engine and properly timed to determine if the valves were in fact bent. If all of the cylinders have a 80 percent hold and not leaking, then the engine is fine. If there is a mass leak on a cylinder, then the piston did some internal damage. I recommend seeking out a professional, such as one from Your Mechanic, to help you check your engine’s valve train with a leak down tester.

A non-interference engine provides clearance between the valves and pistons, so if the timing belt breaks, you might end up with bent valves, and you might have to have your cylinder heads rebuilt, but the engine isn`t likely to be destroyed.
Under normal driving conditions, a timing belt will last for seven to ten years. The replacement process will take between three and six hours to complete, but you`ll only have to replace the belt once or twice over the lifetime of your Acura.
Acura Major Service – Timing Belt Replacement Costs
Fortunately, the recommended replacement intervals for most timing belts are around 60,000 to 100,000 miles.
Generally, a timing belt that goes bad makes a noticeable ticking or clicking timing belt sound that is unusual. When the timing belt starts falling the ticking or clicking sound becomes pretty audible.
Using the air hose, insert it into the 9⁄16-inch hole wooden block and release compressed air into the cylinder port. Using the compressed air/water method, you will actually be able to see bubbles forming past a bent valve on the intake or exhaust side—the larger the leak, the bigger the bubbles.
Bent Valves
The most common failure of valves is bending or breaking as a result of contact with the pistons. The valves contacting the top of a piston is due to incorrect engine synchronization caused by timing chain/belt breakage and incorrect fitting of new belts and chains.
It is safer to replace the timing belt even earlier than the manufacturer recommends. In general, however, timing belts needs to be replaced from 60,000 miles up to 150,000 miles.
However, if the vehicle has a timing belt, there is a very specific interval for replacing it. Timing belt replacement is generally recommended every 60,000 to more than 100,000 miles, depending on the vehicle manufacturer.
Since the timing belt has such an important job, it`s crucial to have it replaced regularly. In most cases, there is no indication that a timing belt is becoming worn. Often times, it just breaks. That`s why most manufacturers recommend you have your vehicle`s timing belt replaced every 60,000 to 100,000 miles.
One of the best ways to tell if you have a faulty valve seal is to conduct a cold engine test. After your machine hasn`t run for a while — even overnight — the seal is now cool. Once you start the engine, the seal will contract. Damaged seals will leave a small gap.
Most people call this a pinging or rattling sound. This noise is caused by an air/fuel mixture in the engine cylinder being ignited prematurely by the heat of compression as the piston is moving up on the compression stroke.
Partsavatar Auto Parts, Toronto – What are the causes of a bent valve in a car. Engine valve problems begin to occur when your engine is subjected to overheating, lack of lubrication or over-revving. Bent valves will not only damage pistons but also valve guides, camshafts and valve train components.
Replacement of your timing belt can vary from 60,0000km to 100,000km, even up to 150,000km depending on the make and model of your vehicle.
Timing belt replacement varies from car to car. It can vary from 50,000 to 70,000 miles. Some cars, it may be a higher mileage. But, 300,000 miles, does not seem possible at all.
Will a timing belt last 10 years? Most manufacturers recommend replacing the cambelt every 60,000 to 100,000 miles or every 5-7 years, whichever comes first.
The number of shaft revolutions to loss of synchronous motion was recorded and converted to the number of belt revolutions by multiplying the shaft revolutions by the ratio 19/116 (the ratio of the number of pulley teeth to the number of belt teeth). The latter is reported as the belt life.
Most vehicle manufacturers recommend replacing the timing belt at 60,000 miles (100,000 kilometers), but others can go as long as 90,000 or 100,000 miles (145,000 to 160,000 kilometers). Check the schedule for preventive maintenance in your owner`s manual.
Can you drive with a broken timing belt? Your car cannot run with a broken timing belt . By the time the belt snaps, the damage is already done, and you will not be able to drive at all. You will need to have the vehicle towed to an auto repair workshop.
Though timing belts don`t need lubrication, you can lubricate a timing chain. This keeps the rotational system of the crankshaft and camshaft(s) running smoothly. DIY Car Service Parts stocks a wide range of lubricants so that you can maintain your car`s health.
Should I replace the water pump with the timing belt? It is not necessary to replace both at the same time, however, it is highly recommended due to a high risk of engine damage. All parts of the synchronous drive have the same mileage and wear.
A worn timing belt will affect your engine`s starting speed as it is attached to the pulleys that drive the crankshaft. Eventually, the belt can slip on the camshaft drive causing the engine cylinder to open and close at the wrong time.
Cambelts or timing belts usually need to be replaced, usually between 40,000 and 100,000 miles. Alternatively, for lower mileage cars, the belt is advised to be replaced around four or five years.
Sometimes, a timing belt breaks without any warning. However, there are sometimes signs of damage that can save you a huge amount of time and money if you catch them soon enough. If you notice any of these signs, you`ll need a mechanic to check the condition of your timing belt and other engine components.
Because timing belts deteriorate with age, time is even more critical than miles. More timing belts break due to age than mileage.

Timing belt is tight and yet appears to be slipping several teeth when belt is rotated,
ANSWER : This is okay since there are more notches on the belt than the amount on the sprockets. Once you aligned the first time the belt marks will almost never line up perfectly again. The marks are used to put the belt on correctly. They aren’t used as an indicator after the engine is turned again. You should be okay to start the motor as long as timing marks on pulleys line up. If you run into any issues, have a certified technician, like one from YourMechanic, assist you with the replacement of the timing belt.
hi- i got an estimate to replace my timing belt and water pump for my 2012 pilot. Do these figures seem right? Timing belt (35.00)

changing timing belt on 10 year old car with 52k miles, not required till 102 k but decade old belt= bad?
ANSWER : My suggestion would be to take a close look at the belt for microscopic cracks or signs of deterioration. If anything is noted, I would spend the money and replace it as this is a relatively cheap "insurance policy" against the possibility of failure resulting in thousands of dollars of potential damage should it fail. As you know, with this generation of interference engines, a broken belt can cause a nightmare of damage. If you would like to replace your timing belt, a certified technician from YourMechanic can come to your home or office to perform this service.
Serpentine belt tearing apart by pebble & pieces of it getting inside timing belt, motor destroyed
ANSWER : Hi there. I agree with you – this doesn’t pass the ’smell test’. The only way for debris to enter the engine is through the throttle body. Since the throttle body inlet is protected and covered by an air intake on your Ford Fiesta, I highly doubt that this is the source of your problems.
timing belt and driving belt replacement interval
ANSWER : The timing belt should be checked every 24 months or 30K miles and replaced every 48 months or 60k miles. You are not due until 173k for a timing belt replacement, but should get inspected at 143k. The accessory belts should be inspected at every oil change and replaced as needed.
Timing Belt Cover replacement and External Belt too.
ANSWER : The parts are touching likely because either the parts were not installed properly or fasteners may be missing or broken. If oil has been leaking, this can cause the seal around the covers to swell as well causing misalignment. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer inspection of the belt drive to see what is causing the misalignment and offer a more personal diagnosis as well as estimate the proper repairs.
Car stalls after water pump, timing belt, plugs, valves replacements
ANSWER : Many different systems can cause a stalling malfunction on your vehicle. The most common are a fuel pump, fuel filter, spark plugs, battery, wiring fault or a crank/cam sensor. If the timing belt slipped off and caused the components to be damaged this could also cause the vehicle to start. To have this diagnosed properly, have a professional technician, such as one from YourMechanic, inspect the stalling issue and perform any repairs required.
