How Long Does a Car Engine Last After an Overhaul?
1 Answers
An overhauled car engine can last between 5 to 10 years. Engine overhaul refers to the process of disassembling and dismantling the engine, cleaning and inspecting all components, and replacing or repairing necessary parts as needed to restore the engine's performance. After an overhaul, the engine's performance can be restored to over 90% of its original state. An engine should be considered for overhaul when the cylinder's out-of-roundness reaches 0.125mm wear per 100mm of cylinder diameter or when the cylinder's taper wear reaches 0.40mm per 100mm of cylinder diameter. Additionally, certain vehicle symptoms should be taken into account, such as significant loss of power, increased fuel consumption, engine oil burning, blue smoke emission, severe piston slap noise, or abnormal engine sounds.
