the oil filler tube connection under the firewall through the trunk - DID another smoke test after reinstalling the oil dipstick tube ( may or may not have been the culprit after all ) .

Sounds like your starting to get things sorted out.
Vacuum leaks can be pain to track down on these cars.
Everything is under vacuum including the crankcase which is usually under slight pressure on most engines.
When you get the oil fill tube replaced let us know if that fixes the problems.

Since you will be replacing the oil filler tube, I would suggest to replace the accordion hose that goes from the bottom of the AOS to the top of the engine (driver side) as these plastic hoses are 20+ years old and get very brittle with age and heat.
To replace this hose you don't have to remove the intake plenum, as you can get to it from the engine cover behind the driver seat.
