Dave,
We have experienced the same problem. Have been resisting pulling the head
but I think that there is an oil port on the front corner, manifold side of
the block / head. At this time we are guessing that for some reason the head
and block are not perfectly parallel at this corner and under load oil leaks
out between the head, gasket and block. Once it is warmed up it is fine
except on occasion when pushed hard. When cold we let ours idle about five
minutes letting it come to operation temperature for several minutes before
driving off. Then we try and avoid routes, freeways and steep hills, that
would load the engine for anther five minutes or so.
This is not much help in solving the problem. We will keep listening and if I
break down and pull the head will post what we find.
