To find data on the numbere of the engine on the engine is sometimes not so easy. Standard the label is fixed under the engine oil dipstick. However, depending on the car model and the date of its release to manufacturing, the location of signs may vary. In this case, you will have to resort to the technical documentation on the car as it will indicate the exact location of the coveted plaques. If the former owner of the technical documentation is not preserved, it is easy to find in free access in the Internet.
2
Getting started check the purchased car, make sure that the data on the numbere, specified in the documentation on the purchased car, meet roomhave actually specified directly in the Assembly of the car.
3
In the automobile documentation number engine appears in the certificate of vehicle registration (issued before 2010) and in the absence of these data in the evidence room you can see in the passport of the vehicle.
4
Please note that some models of foreign cars (in most cases American production) the number of the engine is simply absent and is not provided by the manufacturer. Information about these vehicle features will also be present in the technical documentation on the car.
5
After you have verified that the data indicated on the motor vehicle, and the data in the documents are identical, contact any division of traffic police, where you will be able to find out, is not listed if the car is stolen and not wanted or for some other reason.

After receiving full information about the purchased car, you can be confident about the purchase and protect yourself from possible problems related to last the life of your used car.

Advice 2 : How to check the engine when buying

When buying a used car it is best to banish it to the service station and to be there for a diagnosis through a specialist. In the case where this is not possible, inspection will have to hold their own. If the body and interior of the car is very clear how to check the engine when buying?

Instruction
1
The external examination. Lift the hood of the car and inspect the engine compartment. Here you should pay attention to oil spots and stains: on a healthy engine shouldn't be. Even slight traces of oil may in the future mean for you, the problems related to his leak. Pay special attention to the areas around the distributor and fuel pump. Ifthe reason for the drip tip can become as leaky gaskets and rubber seals and is loose clamps on the hoses. Another reason for the traces of oil can be a loose fitting cap cylinder head: inspect the junction, make sure it has no traces of oil, no sealant. Even if the current owner before the sale brought the engine in order, he could have something to miss. For example, traces of faulty motor could stay on the inside of the hood, so carefully inspect it.Inspect bolts and nuts: if you are around or you will find scratches, albeit small, it can serve as a clear sign that the motor is at least opened. And well, if in this case the seller to inform you, that the engine recently had a routine overhaul.
2
Inspect condition of oil and antifreeze. Check the oil using the dipstick, the antifreeze - just unscrewing the cap of the appropriate tank or radiator. The oil should be transparent, have a normal, not too viscous and the smell. The oil must be free of impurities or air bubbles, and on the dipstick there should be no divorces or outside of the RAID. The same applies to antifreeze: liquid should be clear, have a characteristic sweet smell and no oil stains or bubbles on the surface.The bubbles in the liquid - the first sign of leaks, remember: this is a very serious problem. In the case of, for example, antifreeze, air bubbles can indicate a coolant leak in the engine because of a leaky gasket or crack in the cylinder head, which is completely unacceptable. The antifreeze corrodes the piston rings and causes the condition of the motor permanent damage.
3
Unscrew the oil fill cap neck. Inspect the cover: in any case, under it or on the edge of the mouth should not be foam or plaque. Dense plaque characteristic white-yellow color means that the engine gets the coolant. About the consequences of such a failure we have already discussed in the previous step.
4
Inspect rubber products and candles. The seals and hoses must not be external signs of damage and cracks.
If in the engine compartment dusty and dirty, please wear gloves and arm with a cloth to inspect all nodes: years of grime can hide many defects.
If possible, remove one or two candles, their appearance can be very telling.
Under normal circumstances, the spark will cover a very thin layer of light gray or light yellow coating, and the electrode may be slightly frayed. Candles with a crack on the insulator surface means that the engine will operate with a thud, and the candle with light rich sediments talking about incorrectly chosen oil. Melted Central electrode of a candle can signal a whole bunch of issues: from early ignition and poor fuel until the fault of the valves or ignition distributor. The formation of a kind of glaze consisting of carbon black, or strong wear of the electrodes means that used fuel or oil with lots of additives. Oily plugs can be a sign of too much oil in the lubricating system, and the more serious wear of rings, cylinders and valve guides. Finally, the soot on the plugs indicates that the mixture or the air filter, which have not changed.
5
Start the engine and pagesuite on the spot. The cranking motor should not make extraneous sounds and screeching. Not to say that the engine should start on the first attempt, regardless of the degree of heating and the weather conditions. To work the motor should smoothly, without interruption. If the engine jerks, there are extraneous vibration, and the rhythm can be called inconsistent, it is likely that the motor troit. This means that not working some of the cylinders. Whilethe reason may be a fault with the ignition system, incorrect operation of one of the candles, burned piston or rich mixture. In any case, the problem should be discussed with the owner.
6
Read the readings. When the engine is running after warming up the arrows of the pressure sensors and oil temperature must be within normal limits, is in the middle position.
7
Look at the smoke from the exhaust pipe. If when starting the engine white smoke appeared abundant, but then after a short period of time is completely gone, it is likely that it was just condensation and not to worry. If the smoke continues to pour out of the exhaust pipe, by its color and smell, you can conduct a rapid diagnosis. So, white smoke, or smoke with a slight bluish tinge, which dissipates quickly and leaves in the air a sweet smell - a clear sign of the presence of antifreeze in the cylinders of the engine. Blue or grey smoke (maybe with a hint of white), which for a time hangs in the air light purple or grey smoke means that the combustion chamber gets the oil. The elimination of both faults can cost you dearly, so it is better not to take chances. Finally, the black smoke means that the fuel and air is burned inefficiently. Ifthe reason can be many faults: SamAccountName air nozzles, leaking injectors, faulty lambda probe or MAF sensor. The consequences are that the engine wear is considerably accelerated, and the exhaust becomes highly toxic.
8
Go for a test drive. It needs to identify those flaws that you might not notice when the engine is idling. Check how the motor responds to the drive of the high and low the motor as it accelerates and behaves in dynamics under load. Alert you need background noise, knock, rough running and loss of power and, of course, the smoke from the exhaust system.
Note
Independent engine control - it is still quite risky, and without proper experience we would not recommend to fully trust its results. If you have any doubts, try before you buy still to arrange inspection of the car at the service station or bring a mechanic friend with you.
Useful advice
If you can not determine whether the car smokes due to the presence of antifreeze or cause smoke is oil, there is a simple test. When the car engine is properly warmed up, cover the exhaust a sheet of white paper for a few seconds: water stains to dry completely, but the spots of oil will remain. But, strictly speaking, in the presence of any of the aforesaid causes smoke, we strongly suggest you to make a purchase.

Advice 3 : Do I need to register the engine

In connection with the new legislative regulations recently entered into force, car owners, there are many questions related to the registration of the motor when it is replaced. Previously, this procedure was mandatory in any situation, and today it rules out some cases.
Do I need to register the engine



To get started right away determine that the registration of the new engine to traffic police is not required in that case, if the brand and model of the new engine is absolutely analogous to the previous or to that provided by the manufacturer of the car. In this situation the driver can safely change the detail without worrying about the consequences and various documents.

If you are replacing the engine is not the same, and at the instance of another model or brand of the manufacturer, you will need to contact the technical supervision of traffic police in your place of residence to obtain a special permit for the replacement parts. Law enforcement agencies will conduct a free appraisal of the vehicle to exclude the possibility of forgery or non-compliance of documents, license plates more. To register a car engine, you need to prepare a number of documents, including a statement of the owner for the work of replacement of the passport of the vehicle and certificate of registration, ID of the owner, copies of the PTS from both sides, the insurance policy for third party liability, all documents of the car owner, who confirmed that it was his property, and receipt of payment of all necessary registration actions.

If you want to replace, for example, the engine VAZ, but due to a long period of service or conditions of purchase of the car the engine number is erased, then when replacing you will not have any problems. If you put the engine identical to those provided in the configuration will not be necessary, and when scanning documents the number on the engine to verify it will not, as was done previously.

You must also remember that if you are installing the motor changes the design of the car or engine performance is significantly different from the previous one, the driver should be required to go through the whole above process, in the future to avoid issues when checking for technical inspection. This applies to all brands of vehicles and engines that are subjected to any structural changes.


Advice 4 : How to check the car engine when buying?

The engine is the heart of the car. Therefore, when buying a car you need to pay close attention to this power unit. If this is not done, then after the purchase of the machine there is a risk of problems with the engine. And this, in turn, may require significant financial costs.
How to check the car engine when buying?
Instruction
1
To test the motor, first you need to open the hood and assess the external condition of the motor. Carefully inspect the rubber bushings, hoses and rubber parts that wear out the fastest. You also need to look under the bottom of the car to ensure no oil stains on the block. If any still available, this means that you need to change any seals or gasket of the engine.
2
The next stage is the assessment of the condition of the spark plugs. The carbon on the contacts of the candles will help to determine whether the cylinder oil is set correctly the motor, how is the quality of fuel refuels the car.
3
Check engine is check all the fluids. If you find that the oil level is less than the maximum level, and the external signs of a leak there, it means the oil is burnt together with fuel. The reason for this phenomenon could be worn piston rings or valve seals. In addition to oil to assess the level of coolant. If it was changed on time, then you will not see dark brown fluid in the expansion tank.
4
To evaluate the performance of the engine can and on external signs. If you are running the starter is making a great effort, this means that either exhibited bad ignition, or the spark is not powerful enough. Be sure to listen if it's even a working engine, do not idle. Discharge from the exhaust pipe can also talk about different problems. Black or gray smoke said blockage of fuel injectors, the white smoke indicates injected into the cylinders of the antifreeze. Take a few prosazovat and look, whether there are noises in the time when the engine is hyped to the limit.
5
The last step is to check the engine while driving. Will appreciate how quickly the car accelerates, it doesn't do it at a set rate. Check out how the engine pulls the car uphill. If you feel that the lifting motor power is not enough, as the speed drops, so the car has serious problems.
