Thrown rods or piston rod breaks happen due to oil problems, over-revving the engine, faulty piston bearings or normal wear and tear. A thrown rod leads to an engine stopped cold in its tracks.Continue Reading
A thrown rod pierces the engine block or causes the piston valve and cylinder unit to jam. In either instance, the event is a costly engine rebuild or replacement.
Proper oil level or lubrication prevents friction and engine overheating. Overheating leads to rod failure due to metal on metal friction, warped valves or warped pistons. Carbon buildup also leads to rod failure due to overheating. This problem shows as dark or black-colored oil. Maintaining the proper oil level and using the proper grade of motor oil minimizes these types of rod breaks.
Over-revving the engine can lead to rod breaks. The revving causes rod failure due to a valve's spring failing or being sucked into the engine.
Faulty bearings cause too much play in a crankshaft and stresses the rod. Continued stress causes metal fatigue and eventual rod failure. Engine knock is the usual symptom. Knocking may also mean worn pistons or worn piston valves. In these instances, auto repair sites recommend replacing the piston valve, rod and crankshaft as a unit.
Good auto maintenance extends an auto's life. However, a vehicle's age or high mileage may lead to a rod failure.Learn more about Engine
To replace a car engine piston, start by removing the connecting rod cap and push the piston upwards and out of the cylinder block using the connecting rod. To install a piston, install the rod bearings, position the rings gaps, set the ring compressor, align the piston, and hammer it into position.Full Answer >
Engine lifter noise may be caused by a faulty lifter, deposits of dirty oil or a bent push rod. The sound is an often irritating ticking that originates under the hood of a car.Full Answer >
The components needed for an engine replacement include the bearings, camshaft, lifters, pistons and piston rings. Other necessary components for engine replacement are cam drives, engine valves, timing belts and chains. Replacement parts must suit the user's make and model car.Full Answer >
As the piston in an engine moves down, a mixture of fuel and air gets drawn into the cylinder, which causes compression. This compression is ignited by the spark plugs, causing the exhaust valve to open to allow the burned fuel mixture to be sent to the exhaust system. An internal combustion engine needs a gasoline-to-air mixture of around 14.7 parts air to one part gasoline (by weight) in order to run efficiently.Full Answer >
