Question 1

A faulty ____ often points to a need for head surfacing, cooling system service, or repair to the engine's fuel or ignition system.

Accepted Answer

A faulty head gasket can cause overheating, loss of coolant, and poor engine performance, which might necessitate head surfacing, cooling system service, or repairs to the engine's fuel or ignition system.

Question 2

If the oil pan is to be removed with the car on a lift, the tool that is MOST-Likely used to raise the car is a(n):

Accepted Answer

A

Question 3

Do not open the radiator cap unless the hose collapses when squeezed.

Accepted Answer

True

Question 4

When it is not possible to prime the system by removing the distributor, either use a(n) ____________________ or remove all spark plugs and crank the engine.

Accepted Answer

The answer of When it is not possible to prime...

Question 5

Late-model cars have ____________________ sensors that will react to the frequency of the vibration of spark knock, retarding spark timing.

Accepted Answer

The answer of Late-model cars have ____________________ sensors that will...

Question 6

Which of the following statements is LEAST-Likely true?

Accepted Answer

Warming up the engine before removing the head is generally not recommended because it can lead to issues such as burns, difficulty handling parts, and potential warping of components due to thermal expansion. The other options are standard practices for ensuring a safe and effective head removal and installation process.

Question 7

While having a discussion, Technician A says that to avoid vapor lock, be sure that all fuel lines are positioned at least 1/2" from any heat source. Technician B says that fuel filters should be positioned where they can be cooled by air. Who is correct?

Accepted Answer

Both technicians are correct. Technician A is correct in stating that fuel lines should be kept away from heat sources to avoid vapor lock, a condition where fuel vaporizes within the fuel line before reaching the engine, causing the engine to stall or run poorly. Technician B is correct in advising that fuel filters should be positioned where they can be cooled by air, as this helps in maintaining the fuel at a lower temperature, reducing the risk of vapor lock and ensuring the fuel system operates efficiently.

Question 8

All of the following statements are true EXCEPT:

Accepted Answer

Acceptable leakage from bearings would not be as high as 300 to 600 drops in a minute; this amount of leakage would indicate a problem rather than an acceptable condition.

Question 9

____________________ can be made by cutting the heads off some bolts and using a hacksaw to cut a screwdriver slot in them.

Accepted Answer

The answer of ____________________ can be made by cutting the...

Question 10

Which of the following statements is LEAST-Likely true?

Accepted Answer

Heavy engine loads during the break-in period of an engine are generally not encouraged because they can cause excessive wear and damage. The break-in period is crucial for ensuring that the engine parts wear in evenly and establish proper seating and operation. The other statements (A, B, D) are generally considered true regarding engine operation and maintenance.

Question 11

Without dowels, damage, especially to an automatic transmission flexplate, can occur in a short period of time.

Accepted Answer

Dowels are crucial for aligning and securing the transmission to the engine, ensuring proper engagement of the flexplate to the torque converter. Without them, misalignment can cause uneven stress and premature wear or damage to the flexplate.

Question 12

Older engines with carburetors were susceptible to ____________________ that occurs when fuel vaporizes in a line and a bubble blocks fuel flow.

Accepted Answer

The answer of Older engines with carburetors were susceptible to...

Question 13

While having a discussion, Technician A says that if the timing is retarded, engine idle will be too high. Technician B says that if the timing is advanced, the idle will be too low. Who is correct?

Accepted Answer

Retarding the timing typically results in a lower idle speed because the spark occurs later, making the engine less efficient at low speeds. Advancing the timing can cause the engine to idle higher, as the spark occurs earlier, making the engine more efficient at low speeds. Therefore, both technicians' statements are incorrect.

Question 14

An engine that has enough piston-to-valve clearance to prevent contact is MOST-Likely known as a(n):

Accepted Answer

A freewheeling engine is designed with enough piston-to-valve clearance to prevent contact between the pistons and valves, even if the timing belt or chain fails. This design helps avoid significant engine damage in such events.

Question 15

Some ____________________ sensors can be triggered by a rattle from a loose valve adjustment or a muffler vibrating against the frame.

Accepted Answer

The answer of Some ____________________ sensors can be triggered by...

Question 16

All of the following statements are true EXCEPT:

Accepted Answer

Oil itself is not flammable at room temperature; it is the vapors from the oil that are flammable. The other statements regarding engine adjustments and characteristics are accurate.

Question 17

Oil consumption might not stabilize until all parts have seated to one another. The customer should not be concerned until the vehicle has been driven at least ____ miles.

Accepted Answer

The answer of Oil consumption might not stabilize until all...

Question 18

When an engine has a distributor ignition system, the lubrication system can usually be primed before installing the distributor.

Accepted Answer

Priming the lubrication system before installing the distributor is a common practice to ensure that oil reaches all critical engine components, reducing the risk of dry starts and wear. The distributor's installation does not directly affect the ability to prime the lubrication system.

Question 19

Engine-to-transmission housing screws provide alignment.

Accepted Answer

Engine-to-transmission housing screws are designed to secure the engine to the transmission, not to provide alignment. Alignment is typically achieved through dowel pins or other alignment features.

Question 20

Engine mount bolts should be used to pull a V-type engine into place.

Accepted Answer

Engine mount bolts should not be used to force or pull an engine into place as this can damage the engine, mounts, or bolts. The engine should be aligned properly before the bolts are installed and tightened.

Quiz 56: Engine Installation, Break In, and In-Chassis Repairs

A faulty ____ often points to a need for head surfacing, cooling system service, or repair to the engine's fuel or ignition system.
