Head gasket failure Quiz

What is the most over stressed gasket in an engine?

• Oil pan gasket

• Head gasket

• Intake manifold gasket

What does an oil leak to the outside of the engine indicate?

• The head gasket has blown between an oil gallery and the intake manifold

• The head gasket has blown between an oil gallery and the outside of the engine

• The engine is overheating due to low coolant

What might a coolant leak to the outside of the engine suggest?

• The head gasket has blown between a coolant passage and the outside of the engine

• The head gasket is blown between the crankcase and coolant passage

• The head gasket has blown between the cylinder and an oil gallery

What could be a consequence of a compression leak to the crankcase?

• Overheating

• Decreased fuel efficiency

• Compromised crankshaft main bearings and seals

What might you expect to see if your head gasket has blown between an oil gallery and coolant passage?

• A milky, frothy sludge that looks like a "milk shake" in your engine oil

• Clear coolant in the reservoir

• Unchanged coolant levels

Why is routine coolant testing and oil testing important?

• To check the color of the fluids

• To ensure proper fluid levels

• To detect potential head gasket failures

What can a compression leak between cylinders cause?

• Overheating

• Compression leaks from one cylinder to the next and exhaust gases to flow back into the intake

• Increased fuel consumption

What is a possible sign of a compression leak to coolant?

• High engine coolant levels

• Sweet-smelling white smoke coming out of your exhaust

• Increased engine temperature without any leaks

What can cause the engine to overheat due to a compression leak to coolant?

• Increased air flow in the engine

• A drop in coolant levels and exhaust gases pressurizing the cooling system

• A more efficient cooling system

What is a symptom of a compression leak to outside?

• A ticking/popping noise

• Overheating

• Excessive smoke
