Before buying a car on the car market, it is very difficult to quickly assess the health of the engine without special tools. And a journey to proven masters takes a lot of time. In addition, a potential buyer pays for it, which ultimately increases the purchase price of a used car. The AvtoVzglyad portal tells how to quickly and fairly accurately diagnose.
The power source of any second-hand car can provide many surprises. Let’s say it has lost power, pierced the cylinder head gasket, there are antifreeze leaks and so on. Outbidding all this is carefully hidden. So what if thick white smoke comes out of the chimney? This car is not warmed up yet. And so forth.
To identify all the shortcomings mentioned above, there is a simple old-fashioned method. To do this, you need to take a condom or a rubber ball with you for examination. Here everyone chooses for himself what is closest to him.
To begin with, we put a contraceptive on the crankcase ventilation outlet. Be sure to fasten the plastic strap so that it does not fly off and start the engine. If the latter is usable, our “ball” won’t inflate, or will inflate quite a bit. And when it gets bigger, the crankcase gases pass through the piston rings and the pistons themselves. This engine is in need of repair. There are simply no other options.
An inflated rubber product indirectly indicates that the engine has an oil burner. To understand this exactly, you need to check the condition of the candles: they should have a thick black soot. And if the consumables are new, they have been intentionally replaced before sale. So something is wrong with the car.
We do a similar “trick” with the cooling system. We put a condom on the neck of the expansion tank and start the engine. If the cylinder head gasket is broken, exhaust gases enter the cooling system and the rubber begins to inflate. The problem is corrected by buying and installing a new gasket, or even grinding the head if necessary. So it is better to avoid such cases.
And if you have the desire and money, you can purchase a turbine pressure tester for a more accurate diagnosis. With its help, determine the strength of the vacuum. This will tell you about the condition of the piston rings. This method is much more effective than compression diagnostics as measurements are performed on a running unit.
