Diagnosing a slow oil leak

Hi all!

I'm new to the forum and very grateful for the community.

I have an A4 in my 1972 Morgan 30' that I have owned for two years. Recently I have found small amounts of oil in my bilge and I believe it is coming from somewhere on the port side of the engine.

I have identified two places that I suspect. One area is a bolt (one of two) that holds a flat panel that is inboard of the throttle lever (picture provided). It looks like oil has been coming out past that bolt and dripping down the side.

The other place is, when I place my finger below the throttle lever (forward of the electronic fuel pump), there is a long skinny tube running from top to bottom that seems to have oil running down it.

Two seasons ago I had to pull the engine and replace the oil seal at the thrust bearing. I have since checked below that bearing and do not feel or see any oil escaping there. So I think that is ruled out.

I would appreciate any tips you may have!
