Camshaft belt noise

What is timing belt noise? How does a timing belt affect the engine? Sometimes, a cambelt will produce a loud noise when the car is running, this happens most often when the vehicle is first started and the engine is cold. A bad tensioner will usually be accompanied by noise.

This noise could be some type of squealing or rattling coming from the timing cover area. Also, when your timing belt is loose, it will cause some drivability issues usually under high load or high rpm.

The camshaft operates the cylinder head valves and rocker arm assembly, which sends fuel into the combustion chamber and expels burnt gases out of the exhaust manifold. When the timing belt starts to wear out, it may create a ticking sound inside the motor. Diagnosing Belt Noise squeak or squeal on a Serpentine Belt - Duration: 7:03. Remember the timing belt drive may not be the only source for noise.

To eliminate the timing belt as the noise problem, spray it with soapy water while it is running. If the noise goes away or decreases, then the timing belt is part of the problem.

Yes you get a right old winning noise when the belt is too tight however some of the new Kevlar belts are noisy for the first 5k or so. If it is "Whiring" then that is due to the cam belt being too tight, this will eventually wear the new water pump bearing and bearings.

The engine actually runs two belts, one to drive the camshafts and another to drive the oil pump, situated in the sump. The oil pump drive belt does not have a separate tensioner.

But in some cases even an expert may not be able to predict a cambelt failure”. After doing a timing belt replacement, your car may make some loud sounds. If this happens, it may be timing belt tensioner noise.

Here are some tips to help you determine if this is the case. The first is to verify it is timing belt tensioner noise. You can determine this by pulling over, opening your hood and listening to where the sounds originate.

That type of ticking noise was caused by a worn camshaft lobe. If your noise is intermittent, most likely it not a camshaft lobe issue and more like an external engine belt tensioner, timing chain tensioner, or something else external.

Bad bearings make a high pitched “whine” or “growling” noise after the engine has been started. If there is noise, and it is identified as coming from behind the timing cover, you should: Remove appropriate components in order to remove the timing belt and check the idler pulley for failure. EcoBlue engines having timing belt failure or being informed that their timing belt has snapped.

Probably the cambelt if you say noise was still there after removing aux belt, and when you either spray or talc aux belt bits of those can work there way on to edge of cam belt and quiet it down temp. Also has coolant level gone down any as water pump can seep antifreeze on to cambelt making it sqeeak. The timing belt was just replaced a few days ago by a mechanic.

Squeaky noise on drive belt.

The noise gets louder and louder and the engine is revved higher and higher. Obviously I suspect the noise if coming from the new timing belt. He could hear a noise from the engine and had it checked.

In this case the problem was not caused by neglect but by a faulty timing belt tension roller. Loud squealing or squeaking is coming from timing belt Inspection Service In order for your engine to operate, it requires several belts. The most important of these is your timing belt – it’s responsible for synchronizing the crank and camshaft rotation to ensure that valves open and close correctly.

Also, a pebble or other foreign object can become imbedded in the belt, causing a tapping, ticking or grinding noise. A spray may quieten the belt as it will cause the belt to slip quietly, but the belt material will absorb this spray and cause the rib surface to dry which means the noise will return. In addition, the spray can cause degradation of the belt compound. Tensioner noise A squeaking or rattling noise coming from the tensioner indicates wear on the tensioner.

HI my ford focus 1. Ford focus: plate. A broken timing belt can cause catastrophic engine damage, therefore it is vital to keep the timing belt in good operating condition.

Unfortunately, the end result of any belt tensioner noise is usually tensioner replacement. If you note any of these abnormal signs during your inspection, replace the tensioner.

If none of these signs are evident, the noise may be issuing from another component and not the tensioner. Lastly, anything with a bearing can have a break in period also, so if you replaced idlers, they can make a whining noise for a short time before the bearing races and balls are perfectly matched.

Id prefer the engine to be cam chain rather than belt as theres (hopefully) less maintenance to think about in the future. Can anyone shed any light on this?
