The T4 turbo is High Pressure with a larger turbine than say a Low pressure T3 therefore resulting in a greater back pressure on the exhaust side.
Could that excess force some oil back into the cylinders? I recall once reading somewhere that T4 turbos were normally 0.9 bar? 1.6 bar seems very high. We need an experts advise here. |
