What happens when the timing belt breaks on a car?

The level of damage caused by a broken timing belt can depend on the type of engine you have in your car. 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.

Why is my timing belt squeaking and cracking?

How often should I replace my timing belt?

You can do a visual check – see if there’s any cracking, glazing, missing teeth or oil contamination. Or you can have a mechanic check the belt for you. Most vehicle manufacturers also recommend that you make timing belt replacement a part of your routine maintenance, replacing it every 60,000 miles. Some belts are good for up to 100,000 miles.

What should I do if my timing belt snaps?

Timing belts don’t often give you a lot of warning when they’re about to give way – they might squeak or chirp, or they might just suddenly break. More often, though, damage is due to wear in the timing belt. You can do a visual check – see if there’s any cracking, glazing, missing teeth or oil contamination.

What are the indicators of a bad timing belt?

Ticking noise coming from the engine. The timing belt is attached by way of a series of pulleys to the engine’s crank and cam shaft. The crankshaft powers the engine’s connecting rods which are attached to pistons inside the combustion chamber. The camshaft operates the cylinder head valves and rocker arm assembly, which…

What are the symptoms of a bad timing belt?

Let’s look at some of the symptoms of a bad or failing timing belt: 1. Engine runs poorly: A worn timing belt can slip, getting out of the proper alignment. 3. Ticking sound coming from engine: A failing timing belt can cause a ticking noise when the car is running.

Does the timing belt ever break or fail?

In most cases, the timing belt breaks due to normal use , i.e., as a result of the natural wear that occurs during operation. If the manufacturer’s maintenance instructions are followed, we can make sure that it doesn’t snap prematurely and perhaps even extend its life, but there will always come a point where it breaks eventually.

What are the common issues after timing belt snaps?

If the timing belt snaps, they run into each other, causing bent valves (most common), cylinder head or camshaft damage, and possibly piston and cylinder wall damage. While it is possible that no damage could occur from a snapped belt on an interference engine, such a case is unlikely.

What happens if the timing belt snaps on an interference engine?

While it is possible that no damage could occur from a snapped belt on an interference engine, such a case is unlikely. In a non-interference engine, the pistons and valves don’t occupy the same space, so if the timing belt snaps, no valve or cylinder damage occurs.

What should I do if my Honda Odyssey timing belt broke?

I have taken the top two timing belt covers off and I noticed the front cam ironically is aligned TDC, but the top back cam is 180 degrees away from its TDC. The crankshaft is close to TDC. I don’t have the money to take the car in to pay thousands of dollars to have this done…a luxury I cannot afford right now. Any advice?

How can I tell if my timing belt is right?

Another way you can check if you’re in the right ballpark is to remove the spark plug on the number 1 cylinder and put something long (screwdriver or socket extension) in the chamber and turn the crank pulley with the breaker bar and see where the top of the cylinder’s stroke is. Now that the cam and crank are timed correctly]

Which is more important the camshaft or the timing belt?

Let’s state it plainly – nothing is more important than the timing belt. It drives the camshaft, which is what keeps the valves synchronized, and the crankshaft, which controls the pistons. Your timing belt tells the pistons when to rise and fall, and the valves when to open and close.

What happens if you take the timing belt off an engine?

Warning: If you know you’re working on an interference engine, do not rotate the camshaft or the crankshaft independently while the timing belt is off the engine. You could cause the pistons to hit the valves, or vice versa, and cause the same damage as if the timing belt had snapped with the engine running — bent valves!

Where are the timing marks on a timing belt?

(2a) Find the timing marks on the flywheel and cam, and set them both to TDC. (2b) The flywheel pulley TDC mark is accessible through a hole in the bellhousing. (2c) The camshaft TDC is easy to find — especially if you add white paint as we did.

What happens when your timing belt gives up the ghost?

Your engine’s timing belt is the most important maintenance item in your car. What happens when this component gives up the ghost, and how hard is it to fix by yourself? What Is A Timing Belt?

What happens if your timing belt breaks?

If the timing belt has broken inside, the engine will not be able to turn over or ignite . When you turn the key, you might hear the starter motor engage, but since the timing belt operates the crank and camshaft, it will not turn over. Obviously, if the car won’t start, a phone call to a mechanic is usually the first step.

What happens when the timing belt fails?

When the timing belt fails, suddenly the piston strokes and camshaft are no longer in sync with each other. That means that the pistons are headed upward in the cylinders while the valves are stuck open and not moving anymore.

Will a broken timing belt cause engine damage?

A broken timing belt can cause catastrophic engine damage, therefore it is vital to keep the timing belt in good operating condition. Check the belt during routine maintenance and always ensure that the belt is changed at the manufacturer’s recommended change intervals.

Why did I change my timing belt on my Peugeot 407?

Last week i asked an independent garage to change a timing belt kit (contitech) and timing chain kit ( Febi Bilstein) that i sourced myself from a reputable source. The reason i also wanted to replace the chain is that i felt it was worn, it was probably starting to rub against the casing causing a slight noise over the usual idle sound.

How does the timing belt work in an interference engine?

An interference type engine means that the valve’s stroke and piston’s stroke take up the same space in the cylinder, so the timing belt essentially keeps them from smashing into each other, since they do it at different times.

What are the symptoms of a faulty timing belt?

Can a worn out timing belt cause a fire?

Engine misfires A worn out timing belt might also impact the engine’s fire rate. The timing belt is attached to pulleys that drive the crank and camshaft as we’ve indicated above. However, sometimes the belt will slip on the camshaft drive and cause one cylinder to open or close earlier than it should.

The timing belt is critical for all the internal parts to be in sync. If the timing is off, you will surely know it by how the engine runs. Most timing belts need to changed between 80-100K.

Can a bent valve be identified by the timing belt?

Yes Americar, but they would not have made a $450 profit on an unnecessary job. Cristy, read your other thread too. A bent valve is not easily identified even with the head off. With most OHC engines replacing the belt and attempting to start is the standard procedure.

How much does a bent timing belt cost?

They called me two days later to tell me the valves were bent and this would cost another $3500 to fix. I called other shops and they said they could fix the cylinder head (with a used part) and replace the timing belt for $2,200 all together.

What to do if your engine has a bent valve?

Turn the engine over by hand a couple of times to make sure no internal components are contacting before you button everything back up. If the timing belt were to snap on an interference engine, there is a very good chance that a piston will contact a valve and bend that valve.
