In general, a used car with a diesel engine is the best option only if it was chosen cleverly and served well. This is why choosing a used diesel pickup is a tricky affair. Check these recommendations from Indy Auto Man used car dealer center, Indiana, to be prepared for buying the vehicle, which will be your favoriete for years ahead.
Most US pickup owners will confirm that there is nothing better than good old diesel engine trucks: they are economical, durable, powerful, and can contact water in off-road conditions with no harm. However, diesel engines are often called savings in installments: if it costs the first owner cheaper than gasoline one due to fuel efficiency, then the next owner has to pay for these savings. Unfortunately, the age-related problems of diesel engines are expensive, and their repairs are a thankless investment. Today, the experts from the Indy Auto Man used car dealership share tips on how to check the condition of such a motor and protect yourself from paying for someone else’s mistakes.
So What to Look for?
In general, the inspection of gasoline and diesel engines is not much different. It is indispensable to make sure that there are no extraneous sounds, the motor does not leak oil and antifreeze, check the oil level and the antifreeze level in the expansion tank. But due to the features of the fuel equipment and the absence of the ignition system, it is more difficult to assess the residual life of a diesel engine.
Turbine
The main reason for the increased consumption of diesel oil is the turbine. It usually costs good money to repair, even if the cartridge can be replaced separately. Unfortunately, it is impossible to diagnose a turbine by eye. But after starting the engine, it may be obvious that it needs repair.
Another important detail of the turbine is its originality. If they sell a car with a mileage of 60 thousand, and there is a cheap part, it is better to check the odometer reading. Turbines don’t typically fall apart this early.
Exhaust
The exhaust will help determine the condition of the turbine in the best way. It makes no sense to gas on a cold engine: unlike a gasoline engine, even a cold diesel has the right to smoke a little (even with a particulate filter). It is recommended to warm up the car, better on the go, and proceed to manipulate the gas pedal.
To check the engine properly a potential buyer will need an assistant. For the first time, he must press the gas and hold a slightly increased speed for several seconds (2500-3000 rpm, which is a lot for any diesel engine). If it poured smoke of any color, the car does not worth time and money. This indicates at least a worn piston. When the diesel engine is warm, there should be no smoke at these speeds for at least the first few seconds. If there is almost no smoke, the assistant should press the gas pedal a few seconds harder so that the speed rises to at least 4000 rpm.
Smoke Color
Oddly enough, the most harmless result is black smoke. It means that unburned diesel fuel flies out of the pipe. There can be many reasons: from leaky pipes to current injectors and a dead turbine. If there is no desire to start life with this machine from repair, it is better to look for another option. In general, there is one rule here: the sooner black smoke falls in this case, the worse. Ideally, there should be no smoke after a few seconds of operation at more than 4000 rpm.
Blue smoke is known to be a sign of burning oil, and the set of problems is somewhat different. Most likely, the turbine is faulty, but it may well be that the motor has already lost compression. In any case, blue smoke is worse than black, and the repairs are usually more expensive. If the car is also difficult to start with a cold engine, then the compression is more likely to be defective. It is also a sign to check the mileage.
