13. Technician A says an engines
main bearing insert has a hole that
must align with the matching bores oil
supply hole. Technician B says that
crankshaft bore alignment can be
checked with a feeler gauge and a
straightedge. Who is correct?

outside micrometer to measure the
diameter of a camshaft journal.
Technician B says a camshaft spins
twice for every revolution of the
crankshaft. Who is correct?

15. Two technicians are discussing
hydraulic lifter preload. Technician A
says excessive preload will cause
high manifold vacuum. Technician B
says insufficient preload will cause
excessive valve train noise. Who is
correct?

16. Technician A says the valves in an
interference engine open further into
the combustion chamber that than
those of a non- interference engine.
Technician B says if the timing belt
were to break in an interference
engine due to a seized bearing or
water pump, damage to the valves or
pistons may occur.

18. Two technicians are discussing
the ECT (Engine Coolant
Temperature) sensor. Technician A
says the performance of this sensor
has no effect on engine timing.
Technician B says this sensor will
effect the engines fuel mixture.

scoring on the surface of a flywheel
can be removed during resurfacing.
Technician B says if the ring gear on
a Flywheel shows excessive wear it
may be removed and replaced.
