Find the Error
With the helpful support of brian (Rarly8) i check all possible source.
- oil line check ball is in place at the sending unit
- measure the flow of the oil to the turbo and the scavange flow back to the pump
First i check the check ball:
all right!
Second measure the flow: (the difference of cold and warm oil is huge)
The problem ist just with warm oil (more flow)
