Engine Lubrication Components
Removes contaminates from the engine oil
What is a Oil Filter?
Disperses/removes heat from the coolant system
What is the radiator
System that allows the engine to stay at operating temperature at all speeds
What is the cooling system
A technician finds oil around the top of the cylinder head
What is a Valve Cover Gasket leak?
Type of bolt where the shank is designed to stretch and spring back up to its yield point when tightened
Torque to yield bolt
Pressurizes oil through the lubrication system
What is a Oil Pump?
Regulates the coolant flow to the radiator
What is a thermostat
Regular oil system most vehicles have
What is Wet Sump Lubrication System/Wet Sump?
A technician finds the oil filter to be ballooned and the oil pressure is below normal at high rpm.
What is a faulty Oil Filter/Bypass Valve/ Oil Filter Bypass Valve?
Gasket that seals combustion pressure, situated between the cylinder head and the block
Passages where oil travels inside the engine and head assembly
What is oil gallery/oil galleries
Circulates coolant throughout the cooling system
What is the water pump
Oil system that has a separate reservoir
What is Dry Sump Lubrication System/Dry Sump?
An engine is overheating and has white smoke coming out of the tailpipe.
What is a failed Head Gasket
The measurement of how fast a liquid flows. Also known as the thickness of fluids
What is viscosity
Opens when the filter gets plugged and allows unfiltered oil to reach engine components
What is an oil bypass valve/bypass valve?
Controls the coolant pressure in the cooling system
What is the radiator pressure cap/coolant pressure cap
Sensor with an internal diaphragm that responds to pressure, which is connected to a variable resistor
What is an oil pressure sensor
An engine is burning oil and emits blue smoke
What is faulty Piston Rings/Valve Seals/PCV Valve?
Silicone sealing product that is aerobic
What is room temperature volcanizing (RTV) sealant
Screen that keeps large debris from damaging the oil pump
What is the oil strainer
Current running through an electrolyte, measured with a voltmeter
What is electrolysis
System that provides a continuous flow of fresh air through the crankcase to relieve the pressure
What is the positive crankcase ventilation (PCV) system
An engine overheats only while the vehicle is not moving.
What is a faulty Engine Cooling Fan/Cooling Fan?
The thin layer of an antifriction coating on a multilayer steel gasket
What is Teflon, nitrile rubber, or Viton
