A thrown rod is usually the result of metal fatigue, insufficient lubrication or over-revving of an engine. When gasoline combusts in a cylinder, it drives the piston head downward, pushing the connecting rod and turning the crankshaft. If the metal is weakened, the connecting rod between the head and crankshaft may break. Poor lubrication can cause friction, and over-revving may produce more force than the connecting rod can handle.Know More
Throwing a rod is usually a catastrophic engine failure. In many cases, it occurs while the piston is on the downstroke and can force the broken end of the rod into vital engine components. If it occurs while the piston is moving upward, it can force the piston head into the top of the cylinder with enough force to fuse the two pieces together. In either case, the engine must usually be replaced.
Keeping an engine properly lubricated is one way to help prevent this kind of damage. Low oil pressure can result in not enough oil inside the piston to keep the bearings of the piston head lubricated. Coupled with the metal fatigue present in a high-mileage engine, a lack of oil can be the final trigger that causes an engine to suffer a thrown rod.Learn more about Engine
Unintended acceleration may mean that a car's throttle is stuck in an open position or that there is a problem with the gas pedal. Mistakes also lead drivers to believe their cars are accelerating on their own.Full Answer >
To find out a particular car's engine type, the driver should know the vehicle identification number, or VIN. The VIN contains 17 characters, and the characters in positions four through nine are the vehicle descriptors, which give information like the car model, body type and engine code. By entering the VIN into an online VIN decoder search tool, a car owner can find the engine type.Full Answer >
Complete engine failure, unusual noises, low oil pressure, loss of power, misfiring, hard starting and overheating are all common signs of a seized engine. Acting on these signs by taking the vehicle to a mechanic or automotive professional is crucial to avoid potential long-term problems.Full Answer >
An engine overhaul is a comprehensive engine tune-up that involves removing and disassembling a vehicle's engine, testing all the components, cleaning and replacing parts as needed and then reassembling the engine. This is done to improve vehicle performance and prolong the life of the engine.Full Answer >
