The causes of excessively high temperatures

The causes of excessively high temperatures
Excessive exhaust gas and turbo temperatures have a number of different causes, including:
1.Poor quality oil – that does not divert heat away from the turbo effectively enough, or carbonises because it cannot withstand the high temperatures generated by a turbocharged engine
2.Excessive oil temperatures – as a result of any number of mechanical/cooling system faults
3.Improper performance remapping – that over delivers fuel beyond the acceptable tolerances of the engine
4.Improper or poorly completed engine modifications – that over deliver fuel, or push the engine beyond its capabilities
5.Poor maintenance/lack of servicing – and the knock on effects of improper oil management
6.Driving style – working the engine too hard before it has had time to warm up, and turning the engine off without letting the turbo slow down and cool off after extended journeys
