Hearing strange noises coming from underneath the bonnet of your car can be worrying, especially if you don’t have any mechanical knowledge. Although it could be a minor issue, you won’t know until you take it into a mechanic to have the car diagnosed. Here are three reasons for knocking or other noises coming from the engine.
Wrong Spark Plugs
One of the reasons for engine knocking is using the wrong spark plugs. Manufacturers will recommend that certain parts be used for their vehicles, and if any other type are used, problems such as engine knocking could arise. The reason spark plugs can cause knocking is because they have a certain heat range, and if the wrong plugs are used, they cannot work correctly.
Water in the Fuel Tank
If there is water in the fuel or the tank, the engine may develop a knocking or pinging sound. Water in the tank can lead to thousands of pounds worth of damage, so when you hear knocking in the engine, you need to seek help from a mechanic with garage services in Gwent. They can siphon out the fuel so it can be replaced, replace the fuel filter, and ensure that no permanent damage has been done to the engine.
Low Oil Level
If your car hasn’t had its oil changed for several months and the oil hasn’t been checked recently, it may be running low. If the oil level gets too low, it can cause the engine to knock. Most mechanics will know immediately where a problem lies due to where the engine is knocking and, if it is in fact the oil level, filling it up should stop the knocking sound.
When you hear noises under the bonnet, you should take your vehicle to a mechanic right away because delaying can only make the problem worse and more expensive to fix.
