Oil circuit — pressure check (Nissan Sunny B13)

Attention! Diesel engines are additionally equipped with oil nozzles that spray oil flow onto the piston bottoms for the purpose of cooling them.

Checking oil pressure

Attention! The given oil pressure values apply to SAE 20W-20 engine oil at a temperature of +80°. At a different temperature or viscosity, the test results may differ slightly from the required values. In case of a very large deviation, the tightness of the oil lines and the oil pump should be checked.
