What causes the head gaskets on an engine to fail?
If the engine overheats, it’s common for head gaskets to fail which introduces coolant inside the engine block within oil galleys. This dilutes the engine oil and causes a lack of lubrication, or excessive heat. Knowing what caused the engine to fail is the first step in determining whether or not an engine rebuild or replacement is needed.
What causes an engine to fail in a car?
In most cases, engine failures are caused by one root source: heat. Whether it’s a failure of the cooling system to keep the engine at an optimal operating temperature, or a lack of oil pressure or clean oil to lubricate moving parts which creates excess friction, most major engine failures can be traced back to these events.
What happens when a car engine overheats?
When any of these occur, different parts of the engine will become damaged. If the engine overheats, it’s common for head gaskets to fail which introduces coolant inside the engine block within oil galleys. This dilutes the engine oil and causes a lack of lubrication, or excessive heat.
What happens if there is no gasoline in the carburetor?

What does it mean when a car engine hesitates?
This is what it means when the car engine hesitates. It is usually the result of a problem with the air and fuel mixture within the combustion chamber. However, there is a long list of other reasons which could be the cause of this hesitation problem too.
When does the car hesitate after filling the gas tank?
The hesitation lasts for probably only a half second, happening a couple of times with a few seconds between. So… pulling out of a gas station onto the highway, 10 seconds later the engine hesitates/sputters for .5 seconds, and then recovers. Then a couple of seconds later another half second hesitation happens.
What causes engine hesitation when fuel meter is set?
The (MAF) sensor monitors the amount of air entering the engine. It then sends that information the engines computer, so it can set fuel metering accordingly. A stuck or failed (MAF) sensor will throw these readings off, and may result in stumbling and hesitation.
What should I do if my car hesitates when I press the gas?
Here’s what you might discover—and what you can do to fix the problem: Dirty air filter. The Fix: Replace the air filter. The spark plugs may be dirty or worn. The Fix: Replace spark plugs. The ignition wires may be bad. The Fix: Inspect and replace ignition wires. Ignition system problems. The Fix: Check distributor cap or rotor.
