Do you listen to an engine noise on your Scion tC when you drive your vehicle? We can understand that this is very disturbing and that you are questioning. Listening such a noise is not always a good signal, but it may also be nothing severe. To support you eliminate this trouble, our team has decided to produce this content to assist you in this research. In order to carry out this research as accurately as possible, we will first concentrate on clicking noises, then on whistling noises and, finally, on engine noises on Scion tC metal type.
I listen to a clicking engine noise Scion tC
In case you recognise a clicking engine noise on your Scion tC, and that this noise is close to a click, you will have to discover the origin location of it to be able to know the cause of it. You will need a mechanical stethoscope or a large screwdriver to locate the original area of these noises.
I listen to a clicking noise coming from my high engine
If you listen to an engine noise on Scion tC, and this noise is based at the top of the engine, it means that it is based at your cylinder head and accompanying components. Two components can be the causes of these engine noises on Scion tC. Either the hydraulic pushers, generally it is because of their defective “hydraulic catch-up” system that we will listen to these clicking noises, often when cold and disappears when hot. Otherwise, it is your the play of your rocker arms or their state of wear that is the issue. In such a case, consider swapping them.
I listen to a noise coming from the bottom engine of my Scion tC
If you have identified the location of origin of engine noise on Scion tC that comes from your low engine, it may be that your rods or piston shafts are the triggers. In both scenarios, the long-term risk is engine failure. These two repairs are very difficult and most mechanics will advise you to change the motor of your Scion tC.
I listen to an engine clicking noise on Scion tC coming from combustion
Finally, if you have the feeling that this clicking noise is connected to the combustion of your engine, there are three possible triggers of it. Verify the state of your glow plugs which if worn can hinder the proper combustion of the fuel mixture. Then, your timing belt may be shifted and may poorly control the timing of the various engine parts to provide good combustion. And finally, the most classic cause, comes from your injection, which is either obstructed or one or more injectors is damaged. In this case, do not hesitate to browse this content which deals in detail with the different injector noises on Scion tC.
Hissing noise / engine friction Scion tC
Engine noise Scion tC close to a bearing
If it is close to a squeaking noise you may have one of the bearings of your engine accessory parts that are reached. So verify the state and try to find the exact origins of this noise by positioning someone at the engine at idle, and if this noise is more likely to appear in high rpm, accelerate and position someone at the engine block to distinguish the location of origin of the noise. The three components whose bearings are often at the origin of these noises are the water pump, the injection pump and the oil pump.
Engine noise Scion tC when releasing or depressing the clutch
In the case that you pay attention to engine noise on Scion tC, but this noise appears mainly when you release or depress your clutch pedal, in such a case it is very likely that your release bearing is worn. Indeed, a worn release bearing will produce a noise close to a bell noise. To have more information about this noise and if you have managed to validate that the release bearing is indeed the reason of your concerns, go here, to find a complete file on release bearing sounds on Scion tC.
Engine noise Scion tC close to a friction
In case that you listen to a motor noise on your Scion tC, and, that this noise is close to a friction, it is likely that one of your belts or one of the parts that triggers it is the origin of your problems.Often, we will start to listen to a motor noise on Scion tC, close to a friction when one of the belts is worn out or when one of the related parts like your alternator, or your tensioner roller is the trouble. So remember to verify their state and go to your technician to change the components in question. If you have been able to target the noise as coming from the belts and you want more information about it, take a look at this content on belt noise on Scion tC for a complete guide.
Metal motor noise Scion tC
In case that you listen to an engine noise on Scion tC and this noise is similar to metal noise, it is possible that this noise comes from your gearbox or clutch. Indeed, a metallic noise in the engine block is often connected with damaged sprockets. Try to verify that this noise comes from the transmission, if this is the case, fairly quickly go to your mechanic or you would get a break down. Finally, the second possibility is that your silent engine blocks or rubber mounts may be dead. This triggers a metallic noise every time your engine moves, either because of a change of pace (acceleration or braking) or, when you pass on roads in poor state. Verify the state of your silentblocks and change them if needed.
