How Many Labor Hours for an Engine Overhaul?
1 Answers
Engine overhaul is an extremely technically challenging project, typically requiring about a week of repair time. Engine Overhaul: An engine overhaul involves completely disassembling the engine and related components, dismantling the entire engine structure, replacing damaged parts, and then reassembling the engine. The entire process is quite complex. Generally, overhauls are necessary due to wear or failure of internal engine components, requiring the engine to be fully disassembled to inspect which parts need replacement, such as piston rings, pistons, bearing shells, crankshaft, connecting rods, etc. At the same time, all related components need to be disassembled and thoroughly cleaned, including the engine block, attached radiator, oil circulation components, and more. Engine Maintenance Cycle: The maintenance cycle varies depending on the type of engine oil used. If mineral oil or semi-synthetic oil is used, under normal operating conditions, the maintenance cycle is about 6 months or 5,000 kilometers; if entry-level full synthetic oil is used, under normal operating conditions, the maintenance cycle is about 8-10 months or 7,500 kilometers; if full synthetic oil is used, under normal operating conditions, the maintenance cycle is about one year or 10,000 kilometers.
