Nissan Sentra B17

Der 1.8-Liter MRA8DE ist ein wartungsarmer Saugmotor mit robuster Kette und unauffälliger Ventilsteuerung — keine Hydrostössel, aber das Ventilspiel muss selten geprüft werden. Typische Altersleiden sind Katalysator-Zerfall bei Einstiegsvarianten und Ölverbrauch nach 150.000 km. Solider Brot-und-Butter-Motor ohne Überraschungen, solange Ölwechsel strikt nach Intervall erfolgen.
