Visual check of the engine

 PERFORMANCE ORDER

  1. Examine the engine from above and from below.
  2. The places which are poorly soiled by oil is not a reason for concern, all engines "sweat" a small amount of lubricant means from time to time.
  3. However you have to find out the cause of oil spots under the parked car and considerable oil dirt on the engine case.
  4. To clear the engine means for cleaning of the engine or the steam-ejecting device.
  5. After a trial trip (it is enough) to check several kilometers from where oil acts.

Possible places of leak

We made the short list of places in which at the Audi engine oil can act:

  • Sealing laying of a bent shaft, camshaft(s) and intermediate shaft (4-cylinder engine). These places are closed by a casing of a gear belt
  • Sealing laying of a cover of a head of the block of cylinders.
  • Sealing laying of a head of the block of cylinders.
  • Sealing laying of the distributor of ignition (model with 4-and 5-cylinder engines).
  • Switches with a hydraulic actuator.
  • Sealing laying of an oil filter.
  • Sealing laying of fastening of an oil filter (model with 4-cylinder engines).
  • Sealing laying of the oil pallet.
  • Sealing laying of a bent shaft behind (oil acts on a dividing arch the transmission engine/case).

 Hint: it is possible to carry out a wash of the engine in so-called harvest parks in which it is possible to use the steam-ejecting device for self-service. At strong pollution it is recommended to sprinkle a little before a sink on the engine means for cleaning and to leave it to work during some time. Surely take with yourself working clothes.
