2-19. As a precaution against error, it is a good practice for two persons to  take  the  liner  measurement  and then  compare  and  check  any discrepancy  between  the  two  sets of readings. 1. True 2. False 2-20. Which  of  the  following  conditions is NOT a cause of abnormal liner wear? 1. Insufficient   lubrication 2. Dirt in the lube oil 3. Improper  starting  procedure 4. High  cooling  water  temperature 2-21. Under  which  of  the  following conditions  are  corrosive  vapors most likely to condense on the cylinder  liner  walls  of  an  engine? 1. While operating at temperatures  exceeding  normal 2. While  operating  with  the  lube oil  pressure  below  normal 3. While warming up after it is first  started 4. While operating in such a way that  normal  lube  oil  pressure is  exceeded 2-22. You are removing a cylinder liner from an engine. When fastening the special liner puller to the liner  studs,  why  must  you  tighten the cap nuts by hand instead of by wrench? 1. Because  the  nuts  cannot  be reached  with  a  wrench 2. Because the cylinder liner could  be  scratched  with  a wrench 3. Because  threads  on  both  nuts and studs could be damaged by a  wrench 4. Because there is some danger that a wrench could be left in the  cylinder  liner 2-23. You  are  inspecting  a  cylinder  head for  cracks. Which of the following is NOT a correct procedure  to  use? 1. Perform  a  compression  test 2. After  bringing  the  piston  of each cylinder to top dead center.  apply  compressed  air 3. Examine by sight or with magnetic  powder 4. Perform  the  hydrostatic  test that is used on a water-jacketed cylinder 2-24. The  gaskets,  which  are  used between  the  mating  surfaces  of  the head and the block of an engine, give this joint which of the following   characteristics? 1. Acid  resistance 2. Protection  against  leakage 3. Rigidity 4. Correct  shape 2-25. What should you do if you discover a  warped  or  distorted  cylinder head  during  an  inspection? 1. Machine  the  head  to  correct tolerance 2. Replace the head as soon as possible 3. Overtorque  the  head  to compensate  for  the  warpage 4. Reduce the load on the engine 2-26. Which  of  the  following  symptoms does NOT indicate fouling in the combustion  chambers? 1. Excessive  oil  pumping 2. Smoky  exhaust 3. Loss of power 4. Low  compression 2-27. Which  of  the  following  valve problems will cause a valve to hang  open? 1. Burned  valve 2. Floating  valve 3. Sticking  valve 4. Bent  valve 11
