Default 400 oil leak

Thanks for all your input / suggestions. The crossover pipes / tubes are
nice and dry as mentioned in my first post. Probably the driest part of
the head. I had checked them years ago and fixed a couple that were
leaking slightly. I sealed them from inside the rocker boxes.
I have lived with this seepage for years, but it may be getting worse, or in
my old age I forget what it was like and beleive it is worse lol!
I think I will work around the Distributor area and see about some leaks
there. Then see about a resealing when I need to take the head off. When I
take the head off I will probably want to take the pan off so as to remove
the pistons for new rings as we do smoke a little. And then I will see
something else......and and....
Perhaps some of you can explain this sealing issue. I understand the sealing
and vacuum process with Loctite or other solutions. What I don't follow is
that there is no water leaking and that is part of the head and even under
some slight pressure.
The oil is only in the rocker boxes and it is draining back in to the sump
and so not in the spark plug area. What is seeping at the spark plug area?
We are over the combustion chamber and beside the head studs......not an
oily area......I could understand water perhaps but not oil.
What am I missing ?
Thanks
