Causes a large car breakdown

The reason for the large car breaks down is often much inexperience of the driver, who can not yet sensitively handle the car, and thus blurs the engine or brakes too hard. The cause of such accidents may also be a desire to save on car parts, which the driver begins to buy the old parts of poor quality or completely unsuited to this type of car, which rides. Through it not only a lot more likely to spoil the different components of the car, but there is a failure of the entire car system. Dangerous situation is also flooding the engine by engine oil. It can be caused by just such mismanagement pouring oil into car or purchasing oil of poor quality, which under the influence of temperature began to crackle.


A small fault in the car - is it worth to go to a mechanic?

Nowadays, the fast pace of life makes that we can not always afford to rest and leisure. So when the car comes to a minor fault, which in no way affects the ride comfort, usually we ignore it. Of course, much it depends on where there was such a small failure and whether it affects the operation of other mechanisms or systems in the car. But keep in mind that even a small problem can lead to much bigger problems. It happens that neglected for a long time fault can lead to more serious damage. As a result, rather than pay less for parts and replace them, we have to bear higher costs related to the comprehensive service.


The oil then drips

In the crankcase of a vehicle engine, motor oil lubricates rotating or sliding surfaces between the crankshaft journal bearings (main bearings and big-end bearings), and rods connecting the pistons to the crankshaft. The oil collects in an oil pan, or sump, at the bottom of the crankcase. In some small engines such as lawn mower engines, dippers on the bottoms of connecting rods dip into the oil at the bottom and splash it around the crankcase as needed to lubricate parts inside. In modern vehicle engines, the oil pump takes oil from the oil pan and sends it through the oil filter into oil galleries, from which the oil lubricates the main bearings holding the crankshaft up at the main journals and camshaft bearings operating the valves. In typical modern vehicles, oil pressure-fed from the oil galleries to the main bearings enters holes in the main journals of the crankshaft. From these holes in the main journals, the oil moves through passageways inside the crankshaft to exit holes in the rod journals to lubricate the rod bearings and connecting rods. Some simpler designs relied on these rapidly moving parts to splash and lubricate the contacting surfaces between the piston rings and interior surfaces of the cylinders. However, in modern designs, there are also passageways through the rods which carry oil from the rod bearings to the rod-piston connections and lubricate the contacting surfaces between the piston rings and interior surfaces of the cylinders. This oil film also serves as a seal between the piston rings and cylinder walls to separate the combustion chamber in the cylinder head from the crankcase. The oil then drips back down into the oil pan.45

Motor oil may also serve as a cooling agent. In some constructions oil is sprayed through a nozzle inside the crankcase onto the piston to provide cooling of specific parts that undergo high temperature strain. On the other hand, the thermal capacity of the oil pool has to be filled, i.e. the oil has to reach its designed temperature range before it can protect the engine under high load. This typically takes longer than heating the main cooling agent ? water or mixtures thereof ? up to its operating temperature. In order to inform the driver about the oil temperature, some older and most high performance or racing engines feature an oil thermometer.

Due to its high viscosity, motor oil is not always the preferred oil for certain applications. Some applications make use of lighter products such as WD-40, when a lighter oil is desired, or honing oil if the desired viscosity needs to be mid-range.6
