Next check the details of the capo cap. If you see any part with rough and inconsistent paint, it is likely that it has been removed or replaced. Continue to check the lead lines of the capo cap.

The first thing to observe is all the details of the engine compartment system after opening the capo. If more new details appear than the rest, it is likely that the machine system has been “touched”. One way to tell when a car is broken is easy is to see if the screw bolts are loose, there are signs of opening or replacing.

There will be a connecting wire between the details of the machine system. They are also marked with a stamp or stamp of the firm. Since it is an old car, this part of the rope is usually no longer new. If it is found that the wiring system is too new and not identical, it may have been changed.
Check for any distortion inside the engine compartment. If the car has been hit badly, it is very difficult to mound like new so it will definitely leave traces.

5. Check the engine temperature
One way to check an old car engine is to check the engine temperature. First, let the car turn on for about 5 minutes. Then touch the safe positions on the engine. If after 5 minutes the engine is not too hot, the engine-cooling system works normally. Conversely, if you start the engine for about 2 – 5 minutes but the engine is hot and can not touch your hands, it will indicate a problem with the engine.
6. Test drive
Test drive will help buyers feel most clearly the car engine condition. When testing an old car, try to test on many types of roads, terrain type as possible such as: crowded streets, long roads or highways, poor and rugged roads, steep roads (possible for cars climbing slopes in the parking garage of the shopping malls) …
The reason is that when walking in the street at an average speed, the motorbike system can operate very stably, run smoothly and smoothly, but with other roads, it is not certain. It takes a test drive of different types of roads to allow the vehicle to easily reveal weaknesses.
With the road, it will be possible to test the car’s acceleration. If the vehicle is sluggishly accelerating, it is clear that the engine is in trouble or the power is no longer the same. With the highest pass, the steepest slope will test the vehicle’s traction. If the vehicle climbs hard, it proves that the vehicle engine has lost its toughness.
Some tips on how to view old car engine is that when you test drive, turn on the air conditioner at maximum capacity to put more pressure on the engine system. Try putting the car in more extreme than usual driving situations like pressure gear, depress the accelerator … to accurately check the vehicle’s operating system status.
7. Watch out for the Check Engine light
The Check Engine light is the engine fault indicator. If the light is on, there is a malfunction in the engine. In the process of checking an old car, if the Check Engine light is on, it’s best to check it carefully.
8. Check for excess
With oil motorcycles, it is easier to check the excess gas. Because the machine is often running strong, the flow is a bit excess, so it is easy to feel. To check for excess gas, just leave the engine running, open the engine oil cap and place your hand on the top of the lid. If you feel the push on your hand does not have black smoke, it means the engine is fine.
9. Observe the exhaust pipe
Some older cars have “worn out” engines that often emit a spark in the exhaust. The ignition spark plug does not burn all fuel or the fuel is pumped too much into the explosion chamber, causing the vehicle to appear fire gushing from the vehicle’s explosion tube. In addition, damaged electrical system, engine sensor, exhaust sensor will cause the above phenomenon. Therefore, if you see a fire coming out of the exhaust of the car, check the spark plugs, exhaust system, electrical system and engine sensors of the vehicle.
In addition, the exhaust color should also be observed. With diesel engine, if the exhaust gas is black, dark brown, light blue, white … the engine is having problems, while the light brown color means the engine is working well. With gasoline engine cars, white, black / black blue exhaust … are also signs that the engine is having problems. Colorless or light blue exhaust is a good engine.
