What my car tells me - learning to understand the sounds of driving!
Hearing something whistle, squeak or rattle in the car, you should literally prick up your ears. A trained ear could prevent dangerous situations, costly repairs or car breakdowns. In this article, you will read how to identify the most common driving sounds. Systematic Narrowing In a moving car, there is movement in every nook and cranny. The engine is running, the gears are shifting, the wheels are rolling down the road, the suspension is bouncing, the exhaust is swinging on the bottom, blowing off the exhaust gases. Systematic action is required to identify these specific driving sounds. If possible, disable as many systems as possible to track down the cause of the noise like a detective. Therefore, the most important condition of your search is smooth driving. Ideally, find a place where other road users are not expected. In any case, it should be an asphalt road. Hits and kicks...
Engine tuning: more power, less consumption, better performance!
The engines of the new factory vehicles are calibrated for medium power development. If you want to make your car more efficient and perform better, engine tuning is the smart thing to do. There are many possibilities. Arctic temperatures, like desert heat, are rare in Europe, so many of the default settings are redundant. With these calibrations, manufacturers make a compromise between performance and service life with minimal maintenance. And what's more: they consume performance that can be returned to the car with professional help. Engineers must take into account all possible weather conditions. Types of tuning Tuning is not limited to mechanical interventions in the engine, although everything once started there with the retrofitting of turbo boosters, compressors, nitrous oxide injection, etc. Time and time again, technological advances have created new opportunities to improve vehicle performance. Currently…
Valve seal. Valve cover gasket - signs of damage and replacement.
The valve cover gasket (also known as the valve seal) seals the connection between the valve cover and the cylinder head. Its damage is one of the common causes of engine oil leaks in older cars. What causes its damage? We asked an expert about it. We also checked what solutions mechanics use to “help” a gasket that is not sealing. Engine oil leaks are extremely dangerous. They can lead to accelerated wear or seizure of the drive unit. Especially when we are dealing with a customer who looks under the hood only when the oil level indicator lights up on the car’s dashboard. Valve cover gasket - what is it for and how does it work? The valve cover is designed to protect the camshafts, valves and additional components of the valve timing system installed in the cylinder head…
Honing car engine
Any motor sooner or later develops its resource, no matter how carefully it is exploited. When a unit is overhauled, the master performs many complex operations that require extreme precision. Among them is cylinder honing. Let us consider in more detail what the essence of this procedure is, how it is performed, and whether there is any alternative for it. What is Engine Cylinder Honing Engine honing is the final procedure after a powertrain overhaul. It is similar to grinding and polishing, only in comparison with them it has more efficiency. If you look at the surface of the cylinders after the procedure, then small risks in the form of a fine mesh will be clearly visible on it. Most modern internal combustion engines undergo such processing at the factory. Master…
Replacing the pump on the Priora 16 valves
One of the most important parts in a car is the pump. It is a pump that circulates coolant through the system. If for any reason the pump stops working, then this coolant will begin to heat up, which is fraught with further boiling. On a 16-valve prior, the pump is considered a part that is often subject to wear. Manufacturers recommend changing it after 55 thousand kilometers. Sometimes it happens that it lasts longer, and it is changed at about 75 thousand kilometers. Causes of pump failure on Priore The main reasons why you can determine that the pump has failed ahead of time: leakage of coolant from the pump. Under it there is a special hole, looking into which you can see this leak; ...

Replacing the timing belt with Lada Priora 16 valves
The timing belt synchronizes the mutual rotation of the crankshaft and camshafts. Without ensuring this process, the operation of the engine is impossible in principle. Therefore, the procedure and timing of belt replacement should be approached responsibly. Scheduled and unscheduled replacement of the timing belt During operation, the timing belt stretches and loses strength. When critical wear is reached, it can break or move relative to the correct position of the teeth of the camshaft gears. Due to the peculiarities of the 16-valve Priora, this is fraught with a meeting of valves with cylinders and subsequent costly repairs. Replacing the timing belt prior 16 valves According to the service manual, the belt is replaced at a mileage of 45000 km. However, during scheduled maintenance, it is necessary to inspect the timing belt to diagnose premature wear. Reasons for an unscheduled replacement: ...
Blue smoke from the exhaust
When the machine is running, combustion products are emitted from the exhaust, which have passed the stage of muffling the sound and neutralizing harmful substances. This process is always accompanied by the formation of smoke. Especially if the engine is still cold, and the weather is wet or frosty, the smoke will be thicker, since it contains a large amount of condensate (where it comes from, it is described here). However, often the exhaust does not just smoke, but has a certain shade, by which you can determine the condition of the engine. Consider why exhaust smoke has a blue tint. Why it smokes blue smoke from the exhaust pipe The only reason why the smoke has a bluish tint is the combustion of engine oil in the cylinder. Often this problem is accompanied by associated engine problems, for example, it starts to triple, constantly ...
