Miller Brothers Auto Repair would be happy to inspect your vehicle’s engine if it is making strange noises. It’s better to have the inspection done sooner rather than later because some engine noises are the sounds of the engine being damaged. Let’s talk below about the different sounds engines will make and the causes behind the various noises.
Grinding
Metallic or grinding noises can definitely be a sign that the engine is being damaged. The engine will grind if there isn’t enough motor oil circulating through it. This sound is being made by the parts rubbing against each other without proper lubrication. A faulty water pump or alternator may also grind.
Hissing
Generally, if the engine starts hissing at you, it has a vacuum leak. We can stop the hissing sound by replacing the leaking vacuum hose. Another problem that will make hissing or sizzling noises is a fluid leak. When the fluid leaks onto a hot part, it will start to sizzle and hiss as if it were in a frying pan.
Knocking
If your car’s engine is knocking, the pistons could be damaging the cylinders. This happens when the rod bearings are old and too loose. The engine will also knock if you have multiple detonations in the cylinders rather than just one detonation. Problems with the fuel or fuel mixture can cause this issue.
Popping
Strange popping noises generally come from the exhaust system. Instead of popping, the noises may also sound like tapping. This is an indication that you’ve got a leak in the exhaust manifold. This leak can fill the engine will exhaust gases and directly affect its overall performance. The performance will lag.
Rumbling
You might also hear popping if the catalytic converter is clogged. You will definitely hear rumbling if the converter has been stolen. Another problem that will make the engine rumble is a muffler with a hole in it. Road debris can fly up and punch out a hole in the muffler that makes your engine rumble and roar.
Squealing
Finally, the engine will squeal if the power steering pump is malfunctioning. It will also emit a shrill if the accessory belt is too loose. This can be caused by a worn accessory belt or a problem with the tensioner. In most cases, you should get about 100,000 miles out of the accessory before it needs to be replaced.
