2. Oil pressure - Wikipedia

   en.wikipedia.org/wiki/Oil_pressure

   Murphy oil pressure gauges with switches that activate on low pressure. Oil pressure is an important factor in the longevity of most internal combustion engines. [1] With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big end bearings ...

3. Variable Cylinder Management - Wikipedia

   en.wikipedia.org/wiki/Variable_Cylinder_Management

   The VCM hydraulic circuit control is defaulted open, meaning that the engine has to build up enough oil pressure on initial startup to disable the rear bank of cylinders. A single solenoid on the rear camshaft is activated to close oil pressure to unlock the cam followers, thereby closing the valves.

4. Oil pump (internal combustion engine) - Wikipedia

   en.wikipedia.org/wiki/Oil_pump_(internal...

   The oil pump is an internal combustion engine part that circulates engine oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine. This lubricates the bearings, allows the use of higher-capacity fluid bearings and also assists in cooling the engine.

5. Variator (variable valve timing) - Wikipedia

   en.wikipedia.org/wiki/Variator_(variable_valve...

   Alfa Romeo's variator is a cylindrical chamber that contains a pressure chamber and piston along with helical splines. Engine oil pressure, moves the internal piston which rotates slightly due to the helical splines and advances the inlet valve timing by 25 degrees. Oil flow to the variator is controlled by a solenoid valve.

6. Crankcase ventilation system - Wikipedia

   en.wikipedia.org/wiki/Crankcase_ventilation_system

   These blow-by gases, if not ventilated, inevitably condense and combine with the oil vapor present in the crankcase, forming oil sludge. Excessive crankcase pressure can furthermore lead to engine oil leaks past the crankshaft seals and other engine seals and gaskets. Therefore, it becomes imperative that a crankcase ventilation system be used.

   Jordan James capped off a 12-play drive that took 6:49 with a three-yard TD run to extend the lead back to two scores with 7:28 to go. Penn State cut Oregon’s lead to a score with 3:41 to go but ...

8. Dry sump - Wikipedia

   en.wikipedia.org/wiki/Dry_sump

   The dry-sump system uses two or more oil pumps and a separate oil reservoir, as opposed to a conventional wet-sump system, which uses only the main sump (U.S.: oil pan) below the engine and a single pump. A dry-sump engine requires a pressure relief valve to regulate negative pressure inside the engine, so internal seals are not inverted.

   Sometimes the old "turn it off and on again" actually works. In this case, try completely signing out of your account then sign back in. Many times, this will help, especially in cases of bad passwords or some simple browser issues.
