Engine Overview and Common Failures
The weight of the F16D3 engine according to the catalog is 127 kg. The engine number F16D3 is located at the junction of the block and the gearbox. Valve sticking is a common issue in engines of this series because the manufacturer has incorrectly matched the clearances between the valve guide and valve stem, resulting in rapid deposits formation and incomplete valve closure. Over time, carbon deposits reach the valve stems and cause them to stick.
The replacement of the timing belt according to the official regulations should be done every 60,000 km, but there are many cases described on forums when it breaks even at 30,000 km, resulting in bent valves and expensive engine repairs.
A major concern for owners of vehicles with engines from this series is the rapid clogging of the intake manifold, which often leads to the failure of the variable geometry system. If there is no desire to clean the manifold every 10,000 km, the EGR valve can be blocked.
Other drawbacks include leaks caused by a clogged PCV system, oil contamination in spark plug wells, short lifespan of high-voltage wires, and regular failure of lambda sensors. In addition, weak points include the thermostat and oil pump, which constantly leak due to gasket issues.
