Engine knock - what do they mean?

Suspicious engine knocks do not bode well. When we hear them, we must prepare ourselves for the visit to the mechanic, and often for the costs associated with replacing parts. However, it is worth remembering that the volume, frequency and the moment of the appearance of the knock allow us to initially determine the source of the problem ourselves.

Shortly speaking

An alarming engine rumble may be due to damage to engine parts. Often these are bushings or pushers for hydraulic systems, among other things. It is worth checking their condition regularly in order to prevent more serious damage.

Damaged acetabulum

When we hear metallic tappingwhich changes with engine speed, most likely, this means damage to the sockets... We must go to the mechanic as soon as possible. If this is delayed, the outlets may rotate, significantly increasing the cost of repairs and can damage the entire engine.

To prevent acetabular failure, it is best to have them preemptively replace having traveled 100 km. The cost of the glass itself is low - you can get it from a few tens of zlotys. Small replacement is more expensivewhich requires removing the oil pan, unscrewing the connecting rod joint and removing the bushings. It is also worth checking if the oil pan is in order and replacing the oil seals. Remember that a possible repair of the crankshaft or the entire engine will cost us much more.

If the destruction of the outlets is not prevented in time, it may turn out that they will need to be replaced. whole crankshaft... It is not always profitable, and sometimes even more profitable. replacement of the entire engine.

Worn out hydraulic lifts

At first, damage to hydraulic lifters can only be heard through a short time after starting the engine... The sound becomes louder, longer and more intense over time. If the disturbing noise persists, the manufacturers recommend replacement of all hydraulic jacks... In a situation where their prices are too high for us, as a last resort they can be replaced with only one cylinder.

A set of hydraulic pushers costs from from several tens to several hundred zlotys... Unfortunately, this is not the end. Additionally, you should replace the old engine oil, oil filter and install a new valve cover gasket.

However, there is a way to significantly reduce the costs associated with the repair and replacement of hydraulic pushers. You can apply preparation for engine regeneration... These types of measures are available for most types of ships. They allow restoration of rubbing surfaces including hydraulic pushers.

What else could have caused the engine knocking?

In addition to damage caused by bushings and hydraulic lifters, interfering sounds can also be caused by other engine parts... It is worth checking the status time chain... Too stretched, it can make a sonorous sound. Most often this means the need to replace it.

Engine noise can also be associated with a malfunction. camshaft... Most often it needs to be replaced, which, unfortunately, is due to rather high cost... Then some people decide to buy a used camshaft and rebuild it.

If we hear disturbing engine noise, it's worth checking too. oil condition... Too low pressure in the lubrication system or neglect to change the oil can be dangerous to our machine. To prevent this from happening, the oil level should be checked regularly and if necessary. exchange and use enhancers.

It is very important to react to engine noise and contact a mechanic as soon as possible. Keep in mind, however, that using preservatives for auto parts will increase durability and prevent some malfunctions. You can find such measures in the Nocar online store.
