Disadvantages of the B5244S engine
The Magneti Marelli model with a buggy electric choke received the majority of complaints.
Phase regulator oil leakage is another well-known engine issue.
Although the timing belt is intended to last 120,000 kilometers, it may burst sooner and cause the valves to bend.
Lubricant consumption frequently occurs when the crankcase ventilation system becomes clogged.
This engine’s supports, thermostat, pump, and fuel pump are also weak points.
