Complaints from car owners with this engine are most often related to oil consumption. The culprit is not only excessive oil consumption, but also constant leaks from gaskets and seals. If a significant drop in lubrication level is ignored, it can cause damage to the bearings. In second place are problems with overheating due to a weak cooling system. Over time, overheating leads to engine block damage and the appearance of the signature knocking in the 4th cylinder.
