Any resolution to this? I'm about to pull my motor out after a rebuild to fix oil leaks aswell.

Well motor has been out 3 times now to try and fix the oil leaks. I'm about to give up.
Has anyone got any ideas?
It's leaking out of the rear main, have tried two 2 piece seals and one regular seal and they all leaked. Crank doesn't seem to be scored or grooved.

Leaking under front cover somewhere aswell we suspect it's the cam seal or gasket between block and aluminium housing.


Any help would be great.
