- While determining the most likely problem of an engine with poor compression test results but acceptable cylinder leakage readings: Technician A says that the problem may be incorrect valve timing. Technician B says that the problem is worn valve seats. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhile discussing camshafts Technician A says valve lift is based only on the height of the cam lobe. Technician B says valve duration is based on the height of the lobe. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forwardWhile determining the cause for air leaking out of the oil throttle body during a cylinder leakage test: Technician A says that a burnt intake valve is indicated. Technician B says that a warped cylinder head or bad head gasket is indicated. Who is correct? Technician A Technician B Both A and B d. Neither A nor Barrow_forward
- True False? Camshaft straightness is checked using V-blocks and a feeler gauge?arrow_forwardTechnician A says that if an engine had good results from a compression test, it will have good results from a cylinder leakage test Technician B says that if an engine had good results from a cylinder leakage test, it will have good results from a running compression test Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardTechnician A says an engine may use one or more valve springs per valve. Technician B says additional valve springs are used to control vibration and increase total pressure. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forward
- Technician A says that delayed shifting can be caused by worn planetary gearset members. Technician B says that delayed shifts or slippage may be caused by leaking hydraulic circuits or sticking spool valves in the valve body. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardWhile discussing the results of an oil pressure test: Technician A says that when the fluid pressures are high, internal leaks, a clogged filter, low oil pump out put, or a faulty pressure regulator valve are indicated. Technician B says that if the fluid pressure increased at the wrong time, an internal leak at the servo or clutch seal is indicated. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardTrue or False? The camshaft is always located in the engine block.arrow_forward
- True or False? Some crankshaft and camshaft timing sensors have a specified gap that must be set during installation.arrow_forwardTechnician A says off-square springs may cause increased stem-to-guide wear. Technician B says excessive spring tension may cause premature camshaft wear. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardTechnician A says that crankshaft counterweights offset the weight of the connecting rods and pistons. Technician B says that crankshaft counterweights are used to dampen crankshaft torsional vibrations. Who is correct? Technician A Technician B Both A and B d. Neither A nor Barrow_forward
