M20 Annoying Oil leak

[lammy]

My 1990 320i cab has an annoying oil leak from the front rhs of the head between the block and head just behind the distributor. It drips down the block and onto the under guard tray or my drive! Can anyone suggest what could cure it. It does not lose coolant or overheat. there is no mayonaise on the filler cap. Could it be head gasket or cam shaft oil seal? It is a 2 owner car 78k miles,with full service history. It has had two head gaskets in its life and one skim of the head. It has also had new cam, followers & rockers at around 60k miles. what could I try to solve the probelm? before biting the bullet and stripping the head off and repalcing the gasket. Where could these leaks come from? Could I try tweaking the head bolts down again? any suggestions. Cheers.

Rocker cover gasket possibly???

I would take a look at the above first, Rocker gasket.
Mine used to leak in exactly the same place, new gasket, and all was sorted.

Mine leaked here, turned out the front, right rocker cover bolt was loose and oil was weeping past.

Cheers all for the suggestions . I'll give them a look and see if that cures it.

Cheers all. A bit late but thought I would post I cured the oil leak! It was the cam shaft oil seal cover plate. The O ring seal was trapped when it was put together last and caused the slow leak.
Hope this helps someone in future.
