Nissan Murano Z52

Reason: spontaneous unwinding of the bolts of attachment of plates of oil channels in the front cover of the engine. Factory moment of puffing weakens, bolts unscrew, oil pressure in the lubrication system drops.

Falling oil pressure, risk of oil starvation

Reason: spontaneous unwinding of bolts fastening plates of oil channels in the front cover of the engine. The factory moment of tightening weakens, the bolts unscrew, the pressure of the oil in the lubrication system drops. The problem is typical for earlier versions of the engine without revision. It manifests itself at higher runs than its predecessors, but is not completely eliminated. Possible after 150-200 thousand. km. Preventive elimination is recommended for any intervention in the HRM (removal of the front cover, application of the thread fixer and reinstallation on the sealant). Cost of elimination: 40-150 thousand ruble.
