12.32.14(b) . high oil pressure; 

Monitor oil temperature and CHT
land as some as possible.

12.32.14(a) . low/zero oil pressure; 

– monitor oil and CHT.
– land as soon as safely possible

12.32.14. State the actions (if any) that the pilot can take to rectify:

12.32.12(e) . high oil temperature. 

high oil temperature can be an indication of:
– insufficient oil
– oil cooler bypass valve stuck open
– inappropriate operation (eg high power low airspeed)
– faulty gauge

12.32.12(d) . low oil temperature; 

low oil temperature is most likely an indication the the oil cooler bypass valve is not working.
Also possibly cowl flaps open at high speed and low power.

12.32.12(c) . fluctuating oil pressure; 

fluctuating oil pressure is probably caused by a sticking pressure relief valve, or a problem with the pump.

12.32.12(b) . high oil pressure; 

High oilressure is probably an indication of a sssstuck pressure relief valve.

12.32.12(a) . low/zero oil pressure; 

A low oil pressure indication can be caused by a number of things:
– low oil quantity
– excessive wear in parts of the engine eg bearings
– a leak in an oil line or tank
– oil pump problems
– pressure relief valve sticking open.
– faulty gauge
among other things.

12.32.12. Identify the possible oil system malfunctions indicated by:

Indications
Abnormal Oil Pressure

Fluctuating oil pressure
– quantity of oil available is low / failure of scavenge pump
Low oil pressure
– low oil quantity (lack of replenishment / leaking tank / broken supply line)
– loss of oil pressure (failure of pressure pump/ pressure line/ failing bearings)
– faulty oil pressure gauge – pressure indication falls but not accompanies by rise in oil temp

High oil pressure
– likely faulty pressure relief valve

Abnormal Oil Temperature
High oil temperature – (general overheating of the engine / probs with lubrication system)

Oil pressure and temperature together
– if low or fluctuating oil pressure occurs in flight with a rise in oil temperature => indicates a serious problem with the lubrication system
Land as soon as possible / Forced landing without power if engine seizes

Actions
– with any problem concerning oil plan to land sooner rather than later

12.32.10(b) . checking the correct oil quantity before flight. 

Oil Quantity
– check oil level during each pre-flight inspection
– the oil level on the dipstick should be between the maximum and minimum levels
– if below the minimum the engine will overheat due to less oil circulating in the engine
– if overfull – the excess oil may be forced out through various parts of the engine
