A turbocharger improves engine power, reduces exhaust smoke density, enhances fuel economy, decreases engine noise, and mitigates the effects of lower-density air at higher altitudes and it achieves this by using an exhaust gas-driven turbine to pressurize the air entering the combustion chambers. Turbocharged models have an intercooler that lowers the temperature of the compressed air intake charge, resulting in increased combustion efficiency, power, and reduced emissions. It is crucial to check for leaks in the oil supply line and tighten any fittings if necessary. If the supply line itself is leaking, it should be replaced. The oil return line should also be inspected for obstructions, as a blocked return line can cause oil loss through the turbocharger seals. Burned oil on the turbine housing is a sign of a blocked return line.
