5 Engine Noises that Require Immediate Attention

Every vehicle makes noises, and these noises do not necessarily mean that something has gone wrong. Some basic noises could be minor ticking or clicking. But a few of such unusual noises then indicate that something is wrong with the car, and you must attend to it immediately. Some major sounds that you could look out for are grinding, squealing, pumping. If you hear any of these noises, you must analyse where the noise is coming from and locate the place. The job becomes much easier if you locate the place, but if you cannot do that, you must take it to a technician who can look at the car and inspect it and tell you about these sounds.

Here are some of the common noises that you may hear:

•Clicking sounds:

A common sound can be heard from under the hood of your vehicle but must be immediately looked at. This clicking sound can indicate that your vehicle must be low on oil, or there could be an oil leakage, or there may be a problem with the oil pump.

•Knocking sounds:

Another common type of sound that can be heard from your vehicle is the knocking sound. If you heard this sound, you must understand that there must be some abnormality with the combustion streams. This could also be accompanied by a certain popping or squeezing sound whenever you accelerate your car. The temperature of this can go up to 4500 Fahrenheit and requires a cooling process as well.

•Timing chain sound:

The latest cars today have such overhead camshafts that have big timing chains. These timing chains are joined with the camshaft that further goes to the crankshaft, ensuring that the valves can be accessed at the right time. The timing chain sounds can be heard if the chains that were supposed to be tight with certain hydraulic tensioners get loose. You must get a technician immediately if you hear those sounds.

•Valve train sound:

This sound has a clicking kind of sound that usually decreases when you increase the engine's RPM. The valve and hydraulic lifters sound can be caused because of worn out or protruding lifters. Sometimes it could also occur because of a low oil pressure which causes the hydraulic lifter to fall. Get it checked by a technician immediately if you hear such sounds.

•Connecting rod sound:

This sound usually comes from the rod bearing surface, and sometimes when there is low oil pressure which causes the bearing, and you have decreased lubrication. It’s for the damages to the crankshaft surfaces and the bearing. It can also be a result of poor maintenance practices, which means that the oil is not changed regularly.
