|---|---|
1. A vacuum gauge is connected to the intake manifold of an engine. The needle fluctuates between (15 and 20 in Hg) at idle. This reading indicates: A A Normal Condition. B Late Ignition or Valve Timing. C A Stuck Valve or Misfire. D A Clogged Exhaust. |
6. Technician A says valve spring installed height is measured from the base of the valve spring retainer to the pocket in the cylinder head. Technician B says the valves margin will not effect its operating temperature. Who is correct? A Technician A B Technician B C Both A and B D Neither Technician A or B |
2. A cast iron engine block is cracked. Technician A says welding is an accepted method of repairing this engine block. Technician B says metal pinning is an accepted method of cracked engine block repair. A Technician A B Technician B C Both A and B D Neither Technician A or B |
7. A technician installs a radiator pressure tester on the radiator of a cold engine. After starting the engine the pressure quickly rises to 18 psi. Technician A says this is a normal condition. Technician B says the engine may have a leaking cylinder head gasket. Who is correct? A Technician A B Technician B C Both A and B D Neither Technician A or B |
3. The least likely to cause low oil pressure in an engine is: A Oil Pressure Valve. B Crankshaft Bearings. C Camshaft Bearings. D Worn Valve Guides. |
8. Two Technicians are discussing the PCV system on an engine. Technician A says a stuck closed PCV valve could cause engine oil seals to leak. Technician B says that the PCV system allows the blow-by gases from the crankcase to flow into the intake manifold for re-combustion. Who is correct? A Technician A B Technician B C Both A and B D Neither Technician A or B |
4. Technician A says that torque to yield bolts can not be used twice. Technician B says that torque to yield bolts can be reused as long as they are cleaned and re-torqued. Who is correct? A Technician A B Technician B C Both A and B D Neither Technician A or B |
9. Technician A says that magnetic particle detection is an acceptable method to detect cracks in aluminum castings. Technician B says a special dye is used to detect cracks in aluminum castings. A Technician A B Technician B C Both A and B D Neither Technician A or B |
5. The best tool for checking crankshaft end-play is a: A Bore gauge B Digital micrometer C Dial indicator D None of the above |
10. A vehicle has white smoke coming from its tailpipe. The cause of this problem is most likely: A Worn Piston Rings. B Blown Head Gasket C Worn Valve Seals D Leaking Fuel Injector |
