A six-cylinder engine has a 1 5 3 6 2 4 firing order. Technician A says that after cylinder number 1 begins its intake stroke, the crankshaft will have to travel 240° before cylinder number 3 begins its intake stoke. Technician B says that when cylinder number 3 and 4 are at TDC, cylinders number 5 and 2 are at BDC.
Who is correct and explain why?
Technician A
Technician B
Both A and B
Neither A nor B

- 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_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_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
- While 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_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_forwardTrue False? Camshaft straightness is checked using V-blocks and a feeler gauge?arrow_forward
- True or False? The camshaft is always located in the engine block.arrow_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_forwardWhile discussing the common causes for cracks developing in a cylinder block or head: Technician A says that the chilling of a hot engine by a sudden rush of cold water or air over the surf ace may cause cracking. Technician B says that excessive overheating is a common cause. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- Technician 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_forwardTrue or False? Some crankshaft and camshaft timing sensors have a specified gap that must be set during installation.arrow_forwardWhich of the following statements is incorrect? Cylinder head bolts must be tightened to the proper amount of torque. Most cylinder head bolts are tightened in a sequence that starts on one end. On some engines, the head bolts are retorqued after the engine has been run and is hot. Many engines use head bolts of different lengths.arrow_forward
