Disadvantages of the Saab B284L engine
This engine’s most well-known issue is its limited timing chain resources;
The ECU and the oil pressure sensor frequently malfunction, which causes the electrician a lot of problems;
Gasket failure brought on by a jammed thermostat frequently results in overheating;
The turbine operates normally; frequently, only the bypass or bypass damper malfunctions;
The gasoline pump and ignition coils are the power unit’s weak points.
