- While 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 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_forwardWhich 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_forward
- Which 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_forwardWhich of the following statements about an oils viscosity is not true? The ability of oil to resist flow is its viscosity. Viscosity is affected by temperature; hot oil flows faster than cold oiL Oil flow is important to the life of an engine. In the API system of oil viscosity classification, the lighter oils receive a higher number. Heavyweight oils are best suited for use in high- temperature regions. Low-weight oils work best in low temperature operations.arrow_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 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_forwardTrue or False? Make sure you locate and adhere to the wet torque specs when tightening a bolt that has been lubricated with oil or any other liquid.arrow_forwardWhile 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_forward
- Technician 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_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
