Two components can be the causes of these engine noises on Scion xB. Either the hydraulic pushers, generally it is because of their defective “hydraulic catch-up” system that we will notice these clicking noises, often when cold and disappears when hot.

I notice an engine clicking noise on Scion xB coming from combustion
Finally, if you have the feeling that this clicking noise is related to the combustion of your engine, there are three possible causes of it. Examine 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 manage the timing of the various engine elements to provide good combustion. And finally, the most classic trigger, comes from your injection, which is either clogged or one or more injectors is damaged.

Engine noise Scion xB 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 origin of this noise by positioning someone at the engine at idle, and if this noise is more likely to manifest in high rpm, accelerate and position someone at the engine block to discover the location of origin of the noise.

Metal motor noise Scion xB
In the event that you notice an engine noise on Scion xB and this noise is close to metal noise, it is possible that this noise comes from your gearbox or clutch. In fact, a metallic noise in the engine block is often associated with damaged sprockets.

Finally, the second possibility is that your silent engine blocks or rubber mounts may be dead. This causes a metallic noise each time your engine moves, either because of a change of pace (acceleration or braking) or, when you drive on roads in poor state. Examine the state of your silentblocks and replace them if required.
