What is a difference between a VR6 and a V6 cylinder configuration?
The V6 uses two cylinder heads, while the VR6 uses only one.
The VR6 is not a reciprocating engine, but the V6 is.
The VR6 uses two cylinder heads, while the V6 uses only one.
The V6 is not a reciprocating engine, but the VR6 is.
What is a "W" cylinder configuration?
A reverse W shaped rotary engine.
Two separate banks of VR configurations.
A slightly wider V configuration.
A "Wankel" design.
Select all that apply. Which are tasks of the piston rings?
Preventing blow-by.
Providing an additional path for factory smoke.
Keeping oil in the crankcase from being sucked into the cylinder.
Transferring heat from the piston to the cylinder walls.
How long have threaded fasteners been around for?
Since 1622
Since at least 300 A.D.

What is the benefit of using "torque-to-yield" fasteners?
They are additional parts to sell.
They prove if a technician is reading the repair manual.
What is a stretch bolt?
Almost the same exact clamping force is applied through each fastener.
What does the term "conrod" mean?
It's a combination of the words "connecting" and "rod".
It's not a term that is used anymore.
It's a type of piston design.
It's a type of rod journal design.
What will happen if you install a machine-cut connecting rod cap backward?
The two misaligned half-circles can damage the bearing, rod, or crankshaft.
Nothing. They are perfect circles, so there is no "backwards".
Oil will not be able to fill the oil gallery inside the rod due to misalignment.
They "wear into place" without causing damage to any components.
