Question 1

Which of the following statements is LEAST-Likely true?

Accepted Answer

Heavy engine loads should not be encouraged during break-in as it can cause excessive wear and damage to the engine components. It is typically recommended to avoid heavy loads or high RPMs during break-in and instead operate the engine at moderate speeds and loads.

Question 2

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

Accepted Answer

knock

Question 3

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

Accepted Answer

Engine mount bolts should be used to secure the engine in place, not to pull it into place. Pulling the engine can cause damage to the mounts and other components. Proper alignment should be achieved before tightening the bolts.

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

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 would indicate excessive leakage and a potential problem, not an acceptable condition.

Question 6

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

Accepted Answer

Opening the radiator cap when the hose collapses when squeezed can result in hot coolant spraying out, causing burns.

Question 7

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

Both technicians are incorrect. If the timing is retarded, engine idle will be too low, while if the timing is advanced, the idle will be too high.

Question 8

Which of the following statements is LEAST-Likely true?

Accepted Answer

Warming up the engine before removing the head is not typically recommended because working on a warm or hot engine can pose safety risks and may not be necessary for head removal. The other options are standard practices for ensuring a proper and safe removal and installation of the engine head.

Question 9

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

Accepted Answer

The distributor ignition system has a separate oil pump that is driven by the camshaft. Therefore, the oil galleries can be filled with oil before installing the distributor. This ensures proper lubrication before starting the engine.

Question 10

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

The answer of If the oil pan is to be...

Question 11

Engine-to-transmission housing screws provide alignment.

Accepted Answer

Engine-to-transmission housing screws are primarily designed for securing the engine to the transmission, not for alignment. Alignment is typically managed by dowel pins or other alignment features.

Question 12

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 often leads to issues with the engine's performance, as it can cause a loss of compression, oil leaks, or coolant leaks. In turn, this can lead to problems with the head surface, cooling system, or fuel/ignition system. The other options listed are not directly related to these issues.

Question 13

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 A and B are correct. Fuel lines positioned at least 1/2" from any heat source can help prevent vapor lock, and fuel filters should be positioned where they can be cooled by air to prevent overheating.

Question 14

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 15

All of the following statements are true EXCEPT:

Accepted Answer

Oil is not flammable at room temperature.

Question 16

____________________ 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 17

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 18

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 19

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 such that even if the engine timing belt or chain fails, the pistons will not come in contact with the valves due to adequate clearance. This is a safety measure that prevents significant engine damage. The other options do not necessarily guarantee adequate piston-to-valve clearance.

Question 20

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

Accepted Answer

Dowels are important in ensuring proper alignment and support in various parts of a vehicle. Without dowels, the transmission flexplate can become misaligned and cause damage in a short amount of time.
