Do you want a normal engine or turbo? When going to buy, let him start to see. Look at the smoke in the exhaust pipe if there is white smoke or not. Is the status easy to install? If it's easy, no smoke, it's perfect.
The engine is probably loose. The solution is to replace the piston ring with a new one. But before changing, try stroking the cylinder, whether it is worn or not
Ok sir, thanks so much. Please i also would like to ask what type of engine oil is best use for this type of truck. And also how can i stroke the cylinder sir. Thanks.
