. Technician A says to use a depth micrometer to measure the piston height. Technician B says in most cases, the piston should be at least 0.030" above the cylinder block deck. Who is correct?

Which of the following is used to check bearing clearance with the crankshaft installed in the block?

When discussing cylinder head removal and installation, Technician A says torque-to-yield (TTY) bolts are used to attach cylinder heads in all automotive engines. Technician B says TTY bolts must always be replaced, never reused when reassembling. Who is correct?

The intake manifold bolts usually have a tightening sequence and specified torque like the cylinder heads, but the sequence usually starts with the middle bolts near the

Once the valve springs are removed and the valve stem seal can be replaced, a special sleeve must be used that fits over the ________ grooves and protects the seal as it is installed.

To pressurize the cylinder when replacing valve stem seals, the engine should be rotated such that the cylinder is ________.

Technician A says that the camshaft position sensor is located in the cylinder head of the engine. Technician B says that the camshaft position sensor is located in the crankcase of the engine. Who is correct?

The _______ is a device that allows the engine to 'breathe' by letting air in and out of the cylinders.

What is the primary function of the piston rings in an engine?

What is the purpose of the camshaft in an internal combustion engine?

Technician A says that the camshaft is driven by the crankshaft through a timing chain or belt. Technician B says that the camshaft operates the intake and exhaust valves. Who is correct?
