After re-routing the crankcase breather from my i30crdi diesell Auto 1.6 d4fb out below the engine ie Atmosphere; took a look past the throttle body into the intake manifold.It had approximately 1mm of black oily sludge coating the whole inside.Upon further inspection I also noticed a little bit of oil from the top of the outlet pipe of the intercooler.When i have time I will pull the entire inlet system pipes and all and clean the whole lot.I can only assume that the oily sludge is either coming from the crankcase breather hence the reason why it was re routed or the turbo centre bearing is leaking oil .
Since owning the car since New 2012. The economy was brilliant 5.2L/100km but as time progressed it gradually went to 7.0L/100km.
The car was always serviced by the local Hyundai dealer and they said they said it was the way we (wife) drives.I even tried turning ac off and no improvement.
So I am looking for my own fix.
Oh by the way cars only done 40000km
