The timing belt or chain in modern engines demands attention. Indeed, in the event of a breakage or serious wear, the engine is threatened with a major overhaul. And the owner gets a lot of money. The AvtoVzglyad portal tells how to understand that problems begin with the node.
The author of these lines had a case on a Datsun mi-DO when the timing belt broke on the road. It happened on the slope and it’s a good thing we got to the side of the road because there was a fully loaded truck behind. In principle, a major overhaul could have been avoided: moving to the right a little earlier, when characteristic sounds appeared under the hood and the car began to shake. It was a jammed water pump that broke the belt teeth. Turn off the engine and he’s saved.
Here we note that VAZ engines are famous for such problems. Their belts often do not withstand the indicated resource. Therefore, it would be good to replace the consumables, together with the guide rollers, after 30,000 km.
Remember one more fact. The spare part installed at the factory lasts longer than the later installed part. It’s in the videos already mentioned. They also wear out. Therefore, over time, you need to control their condition. Plays or mechanical damage are unacceptable. You can understand that something is wrong by the whistling noises that the same conductors make when the motor is running.
Go ahead. In the vast majority of power units, the drive is covered with a plastic housing, so it can only be operated visually by dismantling this housing yourself. We strongly recommend taking such an action, for example, after driving through deep fords or a ferocious “mud mixer”. The fact is that clods of dirt can get under the plastic. This will cause the part to suffer.
And on worn engines, oil seeps through a leaking oil seal on the belt. Unfortunately, this is also only determined by inspection at the elevator.
It is more difficult with a chain drive, because it is located in the drive unit. That is, its condition can be controlled only by disassembling the engine. The chain itself, of course, does not break, but wears out. As a result, the spare part stretches a little, which is enough to jump one tooth. The result is a major renovation.
Here you can avoid trouble only by hearing extraneous sounds, such as ringing, rustling or even rumbling under the hood. Then you need to call a tow truck and take the car to the service. There, the wear of the disk will be determined quite accurately by indirect signs, running computer diagnostics.
