Question 7

10)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?

C) Both A and B
D) Neither A nor B

Question 8

6)All of the following statements are true EXCEPT:

A) acceptable leakage from bearings can be from 300 to 600 drops in a minute.
B) the supply of oil in the primer tank should be enough to fill the new oil filter as well as the oil lines in the block.
C) when oil is apparent at some of the rocker arms, the lubrication system is primed and the valve covers can be installed.
D) some pumps (the internal/external in particular) are not self-priming and must be filled with assembly lube before installation.

Question 9

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

Question 10

8)Which of the following statements is LEAST-Likely true?

A) The first few minutes of an engine's operation are critical to its long life.
B) A new part might look quite smooth to the naked eye. Compared to a used, worn-in part, however, it is quite rough.
C) Heavy engine loads should be encouraged during break-in.
D) Moving parts are continuously separated by a film of oil; only the peaks on rough surfaces touch.

Question 11

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

Question 12

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

Question 13

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?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 14

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

B) freewheeling engine
C) standard engine

9)All of the following statements are true EXCEPT:

A) oil is flammable at room temperature.
B) very few newer engines have mechanical valve clearance adjustment; most are hydraulically compensated.
C) attempting an overhead cam (OHC) adjustment with the engine running results in oil being thrown from the timing chain and cam, making a big mess.
D) hydraulic lifter lash on pushrod engines is best done during engine assembly.
