(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

Measures how much pressure leaks from a cylinder.
leak-down test
Area where fuel and air are burned to create power.
combustion chamber
Terms describing assembled engine sections (short block = lower end; long block = includes heads and valvetrain).
short block / long block
Reference points used to align the camshaft and crankshaft.
timing marks
Opens and closes the engine’s valves at the right time.
camshaft
The main structure of the engine that holds the cylinders and supports other parts.
cylinder block
Circulates engine oil to reduce friction.
oil pump
Circulates coolant through the engine and radiator.
water pump
Control the flow of air/fuel mixture in and exhaust gases out.
valves (Intake/Exhaust)
System that monitors and reports engine faults.
OBD-II (on-board diagnostics)
Connects the piston to the crankshaft.
connecting rod
The top part of the engine that closes the cylinders and contains valves and spark plugs.
cylinder head
The small gap between the valve stem and rocker arm.
valve clearance (lash)
Electronic device used to read trouble codes and data.
scan tool
Tool used to tighten bolts to a specific tightness.
torque wrench
A measure of oil’s thickness or resistance to flow.
viscosity
Measures engine vacuum to diagnose internal problems.
vacuum gauge
Converts the up-and-down motion of pistons into rotary motion.
crankshaft
Regulates engine temperature by controlling coolant flow.
thermostat
Uncontrolled explosion of fuel causing pinging or damage.
knock (detonation)
Checks the engine’s ability to compress air/fuel.
compression test
Holds the engine oil at the bottom of the engine.
oil pan
A code identifying a specific problem.
DTC (diagnostic trouble code)
Moves up and down inside the cylinder to create compression and power.
piston
Connects the crankshaft and camshaft so valves open at the correct time.
timing belt / chain
The proportion of air to fuel in the mixture.
air-fuel ratio
System that removes gases from the crankcase.
PCV (positive crankcase ventilation)
Ratio between cylinder volume at bottom and top of piston travel.
compression ratio
Fluid that removes heat from the engine.
coolant / antifreeze
Seals the surfaces between parts to prevent leaks.
gasket
Delivers fuel from the tank to the injectors.
fuel pump
Creates a spark to ignite the air/fuel mixture.
spark plug
Helps keep the engine spinning smoothly and connects to the transmission.
flywheel
Point where the piston is at the top of its stroke.
TDC (top dead center)
Prevents oil or coolant from leaking out of rotating parts.
seal
Sprays fuel into the engine for combustion.
fuel injector
Reduces friction between moving engine parts (e.g., crank bearings).
bearing
Removes contaminants from engine oil.
oil filter
Cools the engine coolant by air flow.
radiator
System that recirculates exhaust gas to reduce emissions.
EGR (exhaust gas recirculation)
