Car Diagnosing Problems That Trigger Engine Noise

Engine noise suggests a problem has developed that will worsen over time. Unlike a catalytic converter that fails suddenly, pinging, knocking, and clicking sounds tend to slowly build in intensity. If the root causes are addressed during the early stages, they can often be resolved without extensive repairs. On the other hand, if you allow them to persist, you risk exposing your engine to severe – and expensive – damage.

In this article, I’ll describe the most common forms of engine noise and explain what causes them. We’ll take a look at clicking, knocking, pinging, and detonation. If you notice any of the following noises coming from your engine, have the underlying problems fixed quickly. Otherwise, you may unwittingly set the stage for a costly overhaul.

Oil Pressure And Worn Parts

Low oil pressure can cause a clicking noise that grows louder as your RPMs rise. The easiest item to check is your oil level. If it’s low, replenish it. If low levels persist, check for leaks. If you’re unable to find any, have a mechanic check to see whether you’re burning oil.

Next, look at the pressure gauge. If the pressure is low, the valvetrain parts may react noisily. Low oil pressure may be due to an oil pump that has developed a blockage or become worn, or a filter that has become clogged. If you live in a cold area, valvetrain noise may be partly due to using an oil with a heavy viscosity. Switching to a lighter viscosity may reduce the noise.

Bearings, Rods, And Deep Knocks

Deep knocking is caused by severely worn or damaged bearings. It is prevalent in older vehicles, especially those in which the owner has neglected to change the oil and filter on a routine basis. The wearing and damage can also …

Don't Overheat! How to Protect Your Car Engine in Summer

The summer is a great time to take your car out for a ride – The wind in your hair, beautiful weather, and exhilaration of speed is what every serious driver lives for. However, before you hit the road this summer, be sure that your car is adequately prepped to deal with the hot climate. Most cars are prone to overheating, especially during the summer climate. By properly caring for your engine, you can avoid being stuck in hot situations.

How Often to Change Your Oil

If you neglect to change your oil regularly, sludge will accumulate in your engine, greatly diminishing performance, gas mileage, and even causing premature engine failure. Oil changes are especially important in the summer months because oil is used quicker in hot weather.

It is recommended that you change your oil every 4-5 months or 4-5 thousand miles. In summer months, however, you may want to do an oil change every 3-4 months or 3-4 thousand miles. Changing your oil is especially important if you find yourself stuck in traffic in hot weather. Engine sludge accumulates around engine cylinders, pistons, and other engine surfaces – This results in damage to the engine and decreases performance. Also, don’t forget to change your oil filter when performing an oil change! The filter keeps dirt and other harmful materials out of the engine components – a clogged filter will greatly diminish engine performance.

Depending on the prevailing weather, one may choose either a lighter or heavier grade of oil. In the summer, most car experts advise that one uses a heavier oil grade. New synthetic oils can last longer and some are specially designed for certain types of engines. During the summer, it is only natural that engine temperatures will be higher than most other times of the …
