When I was cleaning out the EGR valve (removing all carbon etc) I noticed quite a bit of oil on the inside of the inlet pipe.
This made the carbon soft and sticky.....
I assume this oil originates from possibly the turbo seals?
Currently not putting an excessive amount of oil in.
Performance & economy have improved since cleaning.
Question is: Has anyone else noticed this when cleaning out the EGR valve?
Should I be concerned that it is burning a bit of oil his way?
