Bring your MINI Cooper to Eurotech Auto Service & Repair right away if the engine is squealing. A squealing engine can be a sign that you need to have the accessory belt tightened or replaced. It can also be an indication that the belt needs a new tensioner or pulley. This is just one sound that is cause for concern. Here are other engine sounds you should never hear from your MINI Cooper.
Grinding
If you hear grinding coming from the engine, we recommend you pull the MINI over and call for a tow truck. If you are overdue for an oil change, it’s possible that the oil filter is clogged and you do not have oil circulating through the MINI’s engine. When this happens, engine parts grind against each other. This grinding damages the engine parts and can damage the engine beyond repair.
Hissing
Your MINI Cooper may also make hissing noises if you have a vacuum leak in the engine. The leaking vacuum hose is the engine part that makes the noise. A vacuum leak can also make a suction noise. A hissing sound coming from the engine can also be caused by leaking auto fluid. When the fluid drips onto hot engine parts, it will sizzle and hiss.
Knocking
If you hear knocking noises coming from your MINI’s engine, it’s possible that you have worn rod bearings in the cylinder block. This can damage the cylinders. In addition, the engine will knock if the cylinders are not detonating the air and fuel properly. This can be caused by putting fuel that does not have a high enough octane into the tank or worn spark plugs.
Popping
Popping noises generally mean that there is a problem with the MINI’s exhaust system. You may have a cracked exhaust manifold gasket or there could be a crack in the manifold itself. Sometimes, the noise will sound more like tapping than popping. You may also hear popping if there is a clog in the catalytic converter. Replacing the converter will solve the problem.
Rumbling
Your MINI’s engine may rumble and sound like a race car if you’ve got a muffler that has a hole in it. This can also cause the engine to sound louder than normal. Aside from the muffler, a stolen catalytic converter can cause the same problem.
