Bernica,
Yes I have a windage tray installed, it cam with the Avaid
oil pan.
Tortuga,
I have calibrated the dipstick according to Avaid's procedure - put 9 qrts in from empty - mark dipstick 'Full' - start engine and run until primed, then stop & allow
oil in pan to settle - Mark dipstick 'Low' - top up with
oil to the full mark. It might be worth reducing oil volume to 8 qrts and see if the leak diminishes?
General question for everyone: Do you run 8 or 9 qrts with an FE Avaid pan?
