Removing and installing parts of the lubrication system
  Note
t  If engine damage occurs and it is suspected that the cause of this is oil/fuel mixing (olfactory test of the engine oil), the tandem pump must absolutely be checked for internal tightness → Chapter.
t  If considerable quantities of metal swarf as well as abrasion is found in the engine oil when carrying out engine repairs, carefully clean the oil galleries in order to avoid consequential damage and additionally replace the engine oil cooler as well as the oil filter element.
t  The oil level must not be above the MAX. marking on the oil dipstick - risk of damage to catalytic converter!
