installing

Notes:

If large quantities of metal particles or other
deposits (caused, for example, by partial
seizure of the crankshaft or connecting rod
bearings) are found in the engine oil when
performing repairs, clean the oil passages
thoroughly and replace the oil cooler in order to
prevent further damage from occurring later.
Always replace O-rings, gaskets and oil seals
when performing repairs.
The oil level must not be above the max. mark -
otherwise this can cause damage to the
catalytic converter. Markings Page 17
