Suspicious rattling noises can often be heard when starting the engine of a used car. This is reminiscent of a chain-driven gas distribution mechanism. The outage is fraught
The “voices” of expensive repairs resonate with pain in the heart of a motorist. A frantic search begins on the forums in an attempt to find the answer, and this confuses the person even more. And calling services generally drives me to depression. Especially if there are two chains in the engine design and they are located at the rear of the unit, which is connected to the gearbox. In such cases, the masters say that you need to take the engine out of the engine compartment. Well, everyone already guesses about buying spare parts for tens of thousands of rubles.
Let’s see how we can solve the problem without expensive investments. Remember that over time, due to the wear of the joints and the appearance of development, the timing chain lengthens. This is the first reason for the noise. However, if the ringing disappears after 3-4 seconds of engine operation, the drive is still “alive”, but the tensioner needs to be replaced. Over the years, the spring in this node weakens. As a result, for the first time after starting up the steel “heart”, while there is no necessary oil pressure, this tensioner “runs” with the chain. Hence the strange noises.
The first and easiest option is to fill in a more viscous lubricant. In fact, that’s exactly what overbidding does. We advise you to replace the tensioners, then the chain will continue to work. It is non-destructive and much more reliable.
In most cases, you don’t even need to disassemble the engine. It is enough to get to the timing covers and remove them. After we unscrew the three bolts that hold the parts we are changing, and then we assemble everything in the reverse order. With proper skill, it will take about two hours to work, and the cost of spare parts will not exceed 6,000 rubles. Compare this with the “prices” of services. There, only the dismantling of the power unit will cost at least 25,000 rubles.
