Might it be your oil pump gasket?
Mine is doing pretty much the same thing but it has a 1.6 transplant in the near future so
I am not too worried about the leak now.

OH, and by the way.................
NEVER trust a chiltons manual. Get the FSM Bible. Cost's a pretty penny but is well worth the cost. Probably one of the best buys I have paid for on the Zuki. The chiltons rags are shade tree at best.
