Students have asked these similar questions
A vehicle has had several radiator
replacements, and each time there has been
pinhole leaks in the aluminum. Technician A
states that the engine coolant may need to be
exchanged more often. Technician B states
that the engine grounds should be inspected
closely since this could be the cause. Who is
correct?
Select one:
a. Technician A only
b. Technician B only
c. Both Technicians A and B
d. Neither Technician A nor B
A cylinder leakage (leak-down) test indicates 30% leakage, and air is heard coming out of the air inlet. Technician A says that this is a normal reading for a slightly worn engine. Technician B says that one or more intake valves are defective.
A reddish-colored oil is discovered to be leaking during an engine oil change and inspection: Technician A says it may be from a leak in the cooling system. Technician B says it may be leaking transmission fluid. Who is correct?

- While looking at the results of an oil pressure test: Technician A says that higher than normal readings can be caused by using oil that is too thin. Technician B says that higher than normal readings can be expected on a cold engine. Who is correct? Technician A Technician 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_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_forward
- While discussing the causes of extreme engine bearing damage Technician A says that contaminated and old engine oil could be the cause. Technician B says that a leaking radiator could be the cause. 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_forwardTrue or False? An oil with the classification of 5W-30 has the viscosity of both a 5- and 30-weight oil. The 5W means the oil has a viscosity of 5 when warm and a 30 rating when it is cold.arrow_forward
- 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 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_forwardWhile diagnosing the cause for an engine having good results from a compression test and cylinder leakage test but poor results from a cylinder power balance test: Technician A says that incorrect valve timing is the most likely cause. Technician B says that a severely worn cam lobe is a likely cause. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- Which of the following is not an effective way to determine if an engine has an internal coolant leak? Performing a pressure test on the system Visually inspecting the exhaust, coolant, and engine oil Using a dye penetrant and black light Using a combustion leak testerarrow_forwardTrue or False? A compression gauge will show the amount of air leaking through a cylinder as a percentage.arrow_forwardTechnician A says that oil pan gaskets are often made of cork due to its ability to conform to small imperfections in the oil pan. Technician B says oil pan and valve cover gaskets are often MLS gaskets to account for the different expansion rates between components. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
