I have a 1.6td seaping oil out between the cly head and exh manifold #4 only

  You have baiscally three possibilities.  In order of most likely...
  1) leaking valve cover gasket.  This could be an old cracked gasket,
bent valve cover, burr or dent on the sealing surface on the head, old
gasket stuck on the valve cover, excess blowby pressure and so on.
  2)  Leaking oil pressure sending unit.  It's in that vicinity and the oil
tends to wander back and/or down if the sending unit is leaking.
  3) a crack in the head, into an oil passage.  This is pretty rare as
there aren't many oil passages in the head.
