So, gas mileage is much much better now and the car is less shaky when idling in drive. I'm happy with the results.

one final question for the master. I had to cut a new hose from the oil separator to the dip stuck return. I am concerned that the hose I cut, was a little longer than maybe the OEM part. I wonder if my hose, bends up a little before it bends down, will that impact the flow of the oil. basically not allow it to flow properly to the dip stick??
