When searching for a used car, potential buyers are increasingly faced with models that may have engine problems. Experts from the automotive publication share valuable tips on how to determine whether the engine of a used car you are purchasing has problems after a major overhaul, writes Pravda.Ru.
Experts note that an engine overhaul may include either a partial replacement of parts, such as the cylinder head gasket, piston rings, oil seals and crankshaft liners, or a complete replacement of the piston group. However, it is important to understand that even after repair, trouble-free operation of the engine cannot be guaranteed in the long term.
One of the most obvious signs of a major overhaul is a completely clean engine compartment. In addition, it is worth paying attention to the condition of the sealant at the junction of the cylinder head with the block itself – when the engine is assembled at the factory, the sealant is applied evenly and without excess.
Another reliable sign of a major overhaul can be damage to the bolts securing the cylinder head. Scratches on the bolts caused by tools indicate engine disassembly.
You can also assess the condition of the engine by looking under the oil filler plug – the appearance of a white emulsion under the plug may indicate periodic overheating of the engine or penetration of antifreeze into the engine oil.
Other signs of engine problems include exhaust that has a gray or bluish tinge and the presence of white smoke, which may indicate head gasket problems and coolant getting into the cylinders. Careful inspection and thorough inspection can help avoid any unpleasant surprises when purchasing a used car.
