Case of the oil filter

2 — a cover bolt
9 — sealing laying of the case of the filter
10 — a fastening bolt

11 — the case of the oil filter
12 — the sensor switch of the relay of pressure of oil

If at the working engine and the correct level of oil the signaling device of level of oil does not die away, it is necessary to stop immediately the engine and not to start it before malfunction elimination. If pressure of oil deviates demanded value, address to the Section Diagnostics of malfunctions.


 CHECK

HUNDRED instead of a cover of the oil filter at petrol engines establish the special BMW tool with accession for a manometer. As in most cases such tool available is not present, check is carried out with use of the dismantled sensor of the relay of pressure of oil.

1 Check oil level, if necessary add.
2 Start the engine and warm up it. The temperature of oil should be near +80°С.
3 Sensor of the relay of pressure of oil-12-is on the case of the oil filter-11-. Unscrew a bolt-2-and uncover the oil filter that oil from the filter merged in the engine. There is other execution of the oil filter with a screw cover. Unscrew a cover of the filter and remove it, address to the Section Replacement of impellent oil and the oil filter.

8 Increase engine turns. Check pressure of oil upon 5000 rpm.
9 Unscrew a cover of the filter and remove it that oil flew down in the engine.
10 Insert the sensor of pressure of oil with a sealing ring and fix the moment of 20 N • m. Join the socket and fix it.
11 Replace sealing rings on a cover of the oil filter and the central pipeline. Fix a cover on the case of the oil filter the moment of 25 N • m, address to the Section Replacement of impellent oil and the oil filter.
