Also: When I took it in to the mechanic, he mentioned that he saw loose oil around the oilpan, not sure if it had leaked from there or came out from where it’s leaking above. If the former is true, I would find it odd for multiple seals to go without some external force (i.e. excess pressure)”
Marking the position of the distributor will help to keep the timing right, however (there’s always one of these), pull the distributor straight out, note the position of the plate, rotor and offset drive cog. Draw a diagram or, in these technological days of digital cameras, take a photograph so you can reinstall everything correctly and not 180 degrees out of alignment. The distributor may be tough to remove as the body is aluminium and may be stuck in place. It will come out, usually in a rush and with battered knuckles on your hand.
When replacing the O rings use a little Vaseline to help get them on. Put antiseize on the bolts and a film of antiseize on the distributor body to make it easier to remove if you need to do this again in the distant future.”
