Some Common Issues of BMW 320i Engine

Valve Cracking

Valves are a part of the engine that helps complete the combustion process. This is done by letting air or oil into the cylinder or releasing air/oil from the cylinder. During this process, the valve ruptures due to the high pressure causing oil leaks and requiring maintenance. 

High Fuel Consumption 

In BMW 320i Engines, the combustion rate in the chamber is quite high. The combustion process needs a mixture of air & fuel. That is why the fuel consumption of the BMW 320i engine is high.

Cracked Engine Parts

The main problem that is quite frustrating with the 320i engine is the erosion of the engine parts. Over time, the engine parts such as the crankshaft, valves, piston rings begin to erode. This leads to the escape of fuel gas and, in turn, to a reduction in the efficiency of the engine power.

Fuel Leakage

Fuel leakage is one of the most common problems in high-performance engines. It occurs due to broken valves or pistons as the engine has to withstand higher temperatures and pressures. As a result, the oil starts to drip. This leads to very low efficiency and performance of the BMW 320i engine.

Overheating Of Engine 

The BMW 320i engine often overheats due to excessive heat in the combustion chamber. It also happens due to the use of cheap quality coolant. This can lead to engine damage that will need replacement. It is important that you always maintain your car regularly. Constant engine smoke and damage to engine parts, as well as reduced fuel efficiency, are the result of engine overheating.

BMW 320i Engine Maintenance

With so many common issues that occur with the 320i engine, there is a definite need for proper maintenance of a car. Let’s discuss these maintenance areas:-

Walnut Blasting

It is the cleaning of the intake manifold and the valves that deliver the air-oil mixture into the cylinders. Cleaning is done with high-pressure air from the crushed nuts to remove the carbon in the valves. In general, it increases fuel consumption and helps the car to run smoother and better.

Replacement of Spark Plug

In order for a car engine to function properly, the spark plug needs regular replacement. These little maintenance tips are very helpful and are unavoidable if you want your car to run smoothly. 

Oil Change

You have to keep changing the oil in the engine. High-quality engine oil contributes to better combustion in the cylinder. This in turn contributes to an increase in the performance of the car engine.

Loose parts and Wires

Maintenance of the BMW 320i engine also requires constant checks for loose cables, spark plugs, and other engine parts. In the event of strong vibrations, motor parts and cables begin to loosen from their original position. Therefore, they must be properly maintained, otherwise, they can damage other parts of the engine.

Timing belt Change 

The timing belt also needs replacement in case of wear and tear. Through timely change, the engine can last longer.
