What to Do When the Engine Seizes?
2 Answers
Engine seizure is characterized by the generator stopping rotation. This fault generally requires an overhaul, including replacement of the crankshaft, main bearing shells, and connecting rod bearing shells. In severe cases, the cylinder block may need to be replaced. Below are the reasons for engine seizure: 1. Poor quality of the crankshaft and bearing shells: The smoothness of the journal and bearing surface is inadequate, making it difficult to form an oil film due to insufficient contact area. Additionally, gaps behind the bearing shells cause the alloy and shells to not fully adhere tightly, leading to loosening and blockage of oil holes, which interrupts oil supply and results in dry friction. 2. Incorrect installation of bearing shells: Improper adjustment of clearance, whether the contact area is too large or too small, can make it difficult to form an oil film on the contact surface between the shaft and shells.
Hey buddy, if the engine seizes up, pull over and shut it down immediately—this is no joke! Last week I saw my neighbor Old Zhang's car break down just like that—he drove too hard and forgot to change the oil, and the crankcase got all gummed up. First, turn on the hazard lights and set up the warning triangle, and whatever you do, don’t try to force a restart, or you’ll risk piston rings scoring the cylinder walls and making things even worse. Call for roadside assistance right away to get a tow truck. At the repair shop, they’ll need to open up the engine to check whether it was due to insufficient lubrication or overheating and bearing failure. The mechanic told me prevention is actually super simple: change the full-synthetic oil on time, keep an eye on the coolant temperature gauge, and check the oil level before long trips. A tow might cost a few hundred bucks at most, but engine repairs? You’re looking at at least five grand!
