Does Engine Seizure Require an Overhaul?
1 Answers
Yes, engine seizure necessitates disassembling the engine for repair. Below are relevant explanations regarding engine seizure: 1. Crankshaft Bearing Seizure: Caused by insufficient lubrication leading to crankshaft bearing burning, overheating, and seizing with the crankshaft journal. This condition requires replacement of both the crankshaft and its bearings. 2. Piston Ring Seizure: Similarly due to oil shortage, piston rings and cylinder liners overheat and melt, seizing together. This necessitates replacement of the cylinder liner and piston rings among other components. 3. Valve Drop: Mechanical failure causes valve damage or detachment into the cylinder block, resulting in the piston jamming against the valve and combustion chamber, also requiring engine disassembly for repair.
